It’s that time of year again! With the midnight run of this model bringing the start of the 25th into range the prognosis for the big day is a rare white one – with snow likely almost anywhere.
But 15 days is an eternity in modelling so we can take this with a council depot load of salt.
It’s often not until 10 days out that models will start to get a firm grip on what the weather will be like on Christmas day.
My guess at this range is a quiet one with fog and frost and a high of 6C in London.
Friday, December 10th
24hrs on and, interestingly, the pattern hasn’t completely flipped to something opposite to above…
Saturday, December 11th
The high is more centrally located over the UK with proper cold air from eastern Switzerland eastwards. Cold, calm with frost and fog in London.
Sunday 12th December
Little change though any colder air is even further east. A Eurotrash high with declining air quality.
Monday 13th December
The models are in a state of flux, more so than usual by the looks of it. No change on my thoughts though.
Tuesday 14th December
Another slack flow with any true, cold air well to the east. My guess remains a dull and cold Christmas day after a slight morning frost.
Wednesday 15th December
Within the much more reliable 10-day range now and the GFS is throwing out quite an odd looking chart. It shows a mass of cold air just to our east, the start of a cold spell that takes us up to New Year’s Eve.
Thursday 16th December
My thoughts on Christmas day still remain the same as they were days ago. Cold, calm with a high of 5C. Beyond that GFS is hinting the Atlantic floodgates will open. I suspect it is jumping the gun by a couple of days and we’ll see a couple of cold days, the 27th being notably cold?
Friday 17th December
The GFS having another hiccup overnight. The situation at 0z hours probably 5C and cloudy in London. But it’s a deteriorating situation with 850mb temps plunging from the north – the conditions that could bring being consistent with the title of this blog. But I’d pay little notice to output like this until it is 48-72 hours away.
Saturday 18th December
A classic battleground scenario on the midnight operational. An even spread on ensembles, too. My hunch is that the high pressure will survive long enough for a quiet Christmas day. After that?
Sunday 19th December
GFS wants to bring 11C, outbreaks of rain this morning…
This winter is most likely to be on the colder side of average with near normal rainfall.
While the modelled prognosis for the first half of December looks unsettled with an Atlantic influence evolving from the current chilly NW’ly to a mild SW’ly, local analogues of the climate of London suggest the season could be a bit of a rollercoaster with spells of wet, windy and mild weather alternating with dry, calm and cold.
A large factor to consider this winter is the presence of a slight La Nina that is forecast to evolve cooler. Â
Given the uncertainties involved with the influence of ENSO I’ve decided to stick with analogues found in local data that stretches back to 1797.
Overall then the probabilities for the next 90 days are.
Mean
Probability
Rainfall
Probability
Mild (>5.9C)
14%
Wet (>178mm)
19%
Average (5.1C – 5.9C)
38%
Average (107-177mm)
62%
Cold (<5.1C)
48%
Dry (>107mm)
19%
The above table doesn’t reveal a great deal in that extremes can be hidden in a month or season that finishes broadly average. So I decided to look closer at the winters that were revealed in the analogues.
December
The first month, as already mentioned, looks like it will be on the mild side with possibly a notable storm off the Atlantic before things calm down over Christmas – the period between Boxing Day and New Year’s Eve possibly presenting the best chance of any lying snow in this region.
The below graphs are a smoothed representation of the years revealed in the analogues most similar to this autumn.
What is probably most interesting is that the analogues that shared a similar ENSO / La Nina index to this autumn tended to ‘turbo charge’ any yo-yoing in the weather type, be that super-mild or abnormal cold.
December probabilties for maxima: Mild: 48% Average: 19% Cold: 33%
And precipitation. Wet: 33% Average: 29% Dry: 38%
So, the month overall will be mild and slightly dry
January
The first month of 2022 probably represents this region’s best chance of lying snow this winter. A mild start perhaps with a falling off of temperatures in the final third of the month and a cold spell of a week or so. As with December the influence of La Nina could tend to boost the swings in the pattern.
January probabilties for maxima: Mild: 33% Average: 10% Cold: 57%
And precipitation. Wet: 19% Average: 43% Dry: 38%
Greatest chances for January, then, are cold with average precipitation.
February
The second month may see a slight return of the cold spell in January before temperatures recover for a mild and wet spell in the second half.
February probabilities for maxima. Mild: 33% Average: 15% Cold: 52%
And precipitation. Wet: 38% Average: 38% Dry: 24%
The stats suggest on the cold side overall with average to above average rainfall. Perhaps the depth of the cold skewing any very mild second half of the month?
The extremes that no-one can forecast
As well as the very mild winter of 1989/90 the analogues also revealed the very cold winter of 1978/79. There were others but their occurence makes the probability of a repeat at either extreme at less than 10 per cent.
Luke Howard‘s Climate of London volumes provide a plethora of interesting facts and figures about the atmosphere during a time when few reliable records of London weather were made.
Over a period of just over 20 years he mentions the aurora borealis being sighted somewhere in Britain 15 times.
The first, on March 3rd 1807, describes the phenomenon.
The whole hemisphere very red for some time after sunset which we ascribed to the reflection of light from elevated cirri. Our Manchester correspondent, however, states the same phenomenon at the same time as an Aurora Borealis. Additional communications decisive of this point will be acceptable. The phenomenon was repeated on the 21st which with the preceding and following night was windy.
Seven years later, on April 14th 1814, proceedings were described thus.
Aurora Borealis of late years a very unfrequent visitant in these parts appeared last night with no great degree of splendour but with the usual characteristic marks of this phenomenon. About 11pm when my attention was first called to it there was a body of white light in part intercepted by clouds extending at a moderate elevation from the N to the NW with a short broad streamer rising from each extremity. After this it became an arch composed of similar vertical masses of fibrous light which moved along in succession preserving their polarity and curved arrangement. One large streamer in particular went rapidly through nearly the whole length of the arch from W to E. Some of these masses were rather brilliant and one exhibited colours. After some cessation and a repetition of this appearance carried more towards E and W the light settled in the N and grew fainter in which situation at midnight I ceased to observe itÂ
Further mention is made on 8th February 1817 and later that year, on 26th October, another account.
A little before 8pm I observed from the neighbourhood of Lowestoft, Suffolk, a distinct commencement of Aurora Borealis in the north in white streamers ascending to a considerable elevation which after a minute or two became converted into a still light the latter remaining for an hour or two after was at length obscured by clouds.
And the same year, as shown in the book.
More sightings were recorded on 12th and 17th October 1819 and 14th December of the same year. Also 31st July 1821.
Six years later, on 18th january 1827, an account of the Northern Lights in Epping Forest was noted.
The final case of the aurora of London was made on 25th September 1827.
Further records were noted on 15th September 1828 in Glasgow and 11th December 1830 at Ackworth, Yorkshire
Lots of hype regarding winter at the moment with contradictory model output being released almost daily.
My early take on this is based on the current state of the El Nino Southern Oscillation (ENSO) index which is currently -0.6 and trending more negative (La Nina).
Using analogues from previous events would suggest that the coming winter in the south-east of England will be broadly average in terms of mean temperature and wetter than average.
Looking more closely at each year suggests the following.
Further scrutiny of the local statistics suggest that the mean temperature for November could be lower than average, some 1.7C below average with rainfall around 20 per cent below average.
I should be noted, however, that in the years that were most similar to this September and October (1958, 1961, 1967, 2001, 2005, 2019) the ENSO index was much closer to neutral than it is now. In other words what happens next month could be vastly different to what happened in those years.
Years prior to those mentioned above add intrigue as ENSO statistics are not available.
1802 (cold January 1803), 1849 (severe January 1850 with ice in the Thames) 1862, 1865 (heavy snow southern England 10/11 January) 1874 (notable December storm)
Obviously a lot can change atmospherically in the next few weeks; this is an early take on my usual winter forecast which will be released on December 1st.
I hadn’t heard of Brettenham before this Suffolk village recorded over 100mm of rain from the convergence line event on the afternoon of Sunday, July 26th.
A former Environment Agency observer recorded 181.3mm in 1hr 40mins (1640-1820).
Notable on its own but even more so given that Wattisham, an official station 7.3km to the south-east, recorded just 2.4mm at the same time.
Whilst intensely isolated events happen, and often go unnoticed if they occur in uninhabited areas, this one seems more severe than what has previously been recorded.
The greatest 24hr rainfall recorded, according to Robin Stirling’s Weather of Britain, was 279mm on July 18th 1955 in Dorset. The rainfall far more widespread than the event on Sunday.
The event in Suffolk was covered by the East Anglian Daily Times. A report that mentions ‘rain falling in sheets and roads turned into rivers’ can be found here.
What’s the most ridiculous omen for an England win in the European Championship final against Italy on Sunday? After hearing this on the radio this week I decided to try to find one.
Readers of this blog will know my theories of how the weather and big events seem to be tied together. So it is no surprise that I’ve indeed found one.
Last month, I wrote about summer washouts. The one last month that began on the 17th saw 28mm fall, possibly contributing to what was a dull spectacle; England’s 0-0 draw with Scotland at a rain-soaked Wembley.
While putting together the July list of washouts one of only six events since 1959 began on July 19th 1966. Over 20mm of rain fell, coinciding with England’s group game with France. The Three Lions won the tie thanks to a brace from Liverpool’s Roger Hunt. Days earlier they had been panned after a dull 0-0 draw with Uruguay. No-one, apart from Alf Ramsey, fancied our chances. Yet by the end of the month they were world champions.
So, in terms of football singularities, England’s is one title every 55 years? We’ll know by 11pm on Sunday.
The weather of late has been in stark contrast to the mostly dry, sunny (if a bit chilly) spring many enjoyed. Indeed the first half of June saw more of the same and, locally, was the warmest start to the first meteorological summer month since at least 1959.
My memory of summers years ago was that it was often hot and sunny but I also remember countless days of staring out the window for hours waiting for relentless rain to let up.
Looking back at sunshine stats to 1959 there has been over 4,400 days where no sun was recorded, roughly a one in five chance of a totally cloudy day.
Considering the months where the absence of sun is most noticed, May to October inclusive, the probability decreases to just under one in ten.
To decant these to ‘washout days’ I’ve only included those sunless days that were also ‘wet days’ where 1mm or more of rain was recorded. The probability further decreases to just under one in twenty.
All very interesting but were there more washout days decades ago or is the memory playing tricks?
Looking overall shows an increase since 2013. Out of all the months the most notable change has been August.
Spring in this neck of the woods was really mixed.
A chilly start to March became fairly benign before ending with the warmest March day locally since at least 1959.
April then turned much colder and drier; just 2.4mm of rain fell during the month – the driest April since 2007 and fourth driest in a local rainfall series back to 1797! Sunshine was abundant with over 200 hours. But clear skies at that time of year, with a polar continental airmass, often means air frost. And the ten recorded overnight was far higher than normal.
May saw things warm up slightly but the month still finished a degree colder than average. Some 80mm of rain fell which is over one and a half times what we’d normally expect. The wettest May since 2007 – the month playing catch up on the total absence of April showers that bring the spring flowers! It was a dull month with only 126 hours of sunshine, 69 per cent of average – the dullest since 1990 was third dullest back to 1881.
In terms of flora and fauna the colder weather played havoc with the trees, bud burst coming much later than recent years. As I write this on June 6th some of the later budders like false acacia have only just come into full leaf. The birds, as they normally do, just seem to get on with it raising their young. I’m not sure what the food supply has been like but judging by the amount of healthy juvenile fledglings I’ve seen I would guess that it has been a good season so far?
Here’s the stats. March 8C (+0.3) 30.9mm (76%) 90.9 hours (84%)24.1C on 30th (a record that had stood since 1965) April 7.2C (-2.6) 2.4mm (5.5%) 202.6 hours (127%) 10 air frosts in April, much higher than normal May 12.1 (-1) 80mm (156%) 125.6hours (69%) Spring 2021: Mean : 9.1C (1.1C below average, coldest since 2013, 111th coldest) Rain : 113mm (84% of average, wettest since 2018, 150th wettest ) Sun : 425.4 hrs (94% of average, dullest for three years. 51st dullest) The average masked extremes.
The Scottish Haute Route with lead in and out from Aberdeen to Mallaig
At the end of April I cycled and skied my way across Scotland, from Aberdeen to Mallaig, incorporating the ‘Scottish Haute Route’ across the Grampian Mountains.
The route of some 225 miles has a total ascent of 34,000ft, covering some of the highest peaks in the UK including Ben Nevis. Paths that crossed deep into the Cairngorm national park made it necessary to use a mix of wild camping and b&b accommodation that was open after the lockdown.
Probably against my better judgement I also strapped my skis to the bike to traverse any snow on offer.
I accessed the route by taking the train from Kings Cross to Aberdeen; leaving at 2pm the direct LNER East Coast journey is a real treat, speeding its way through the English and Scottish countryside to arrive just after dark.
The journey started with a cycle into Kings Cross for the 2pm train to Aberdeen
Aberdeen is a bit of a strange city. All that oil money but there seemed to be more than the usual share of depravation. The main drag was like a ghost-town after 10pm – perhaps it was lockdown. I quickly fled back to my hotel.
Day 1: Aberdeen to Ballater 47 miles, 2,500ft (7hrs) Weather: Max 6.9 Min 2.1 Rain 4mm Wind NE 9mph Fisheries, old railway lines, River Dee
The leg from Aberdeen to Ballater generally follows the River Dee
A bit of an inauspicious start in Aberdeen – a glitchy phone led me a merry dance around the town including a tour of the various fisheries by the harbour. I rode back to the city beach to perform the customary wheel dip in the North Sea; a cold day with a freezing onshore breeze and intermittent light rain.
I was soon on my way inland via the A93 and Deeside Cycle Way formed from the Old Deeside Railway Line. A real cycling delight; miles and miles of smooth Tarmac path often very close to the River Dee with its delightful wildlife. Finches of all descriptions seemed to lead the way and far outnumbered people – I probably saw about a dozen others all day.

Day 2: Ballater to Braemar 31 miles, 4,000ft (7hrs) Weather: Max 8.9 Min 0.5 Rain 1.2mm Wind NNW 7.7mph Royal castles, abandoned bothies and steep paths
After staying at the excellent Netherley Guest House I was soon on my way to Crathie where I would ‘turn right’ to finally get off the beaten track for the remoter legs of my trip.
Crathie was far smaller than I imagined – the car park for Balmoral was empty, no doubt a result of it being early season and lockdown having only just been lifted. The B976 was soon heading relentlessly uphill, the first test of my endurance pedalling something like 20kg and the bike. I was soon pushing on the steepest section, a local on a racing bike told me where to leave the road.
The gravel / sand track at the start of the section was excellent and progress quick – I was surprised just how good it was. Another cyclist heading toward me remarked that he hadn’t seen so much on a bike since his cycle trek in Tibet 20 years previously.
On reaching Corndavon Lodge I was faced with my first ford to cross, a relatively simple task were it not for the fact that I’d have to get myself and the machine across. The lodge, the first bothy on the Scottish Ski Club’s 1978 traverse, was boarded up.
I pressed on, soon reaching Loch Builg and on to the ruin of Lochbuilg Lodge. It was at this point that I was faced with a steep, single-track, path up to Carn Drochaid and upward to Ben Avon. It was also at this point that I realised that the weight on my bike was going to make it impossible to adhere to my intention of following all the ridges.
After 15 minutes sat among the ruins I changed my plan and retreated back to the River Gairn. I planned to follow the track to Braemar while keeping one eye on other paths westward – none of which appeared to offer any bike friendly options without double backing to Braemar.
As I ascended the path up the shoulder of the 900m Culardoch it was obvious that I’d made the right choice. Despite good weather it was a real struggle at times. I was also a bit deflated as I looked across the valley at the large cornices on Ben Avon in the distance.
From the plateau of Tom na h-Eilrig it was a general downhill descent into Braemar. Time was getting on and I knew I had to arrange a b&b before the dusk chill turned into night.

Braemar weather station, the coldest place in the UK. -27.2C was recorded here on January 10, 1982
Day 3: Braemar to Glen Feshie 40 miles, 2,159ft (10.5 hrs) Weather: Max 7.7 Min 1.2 Rain 2.4mm Wind NNE 8.2mph Smooth bridleways, rocky paths, rickety old bridges, knee deep fords, bogs
After resolving overnight that I wasn’t going to be able to follow my original planned route across the Cairngorms I’d decided a loose plan to make a decision once I’d reached Linn of Dee, effectively the end of the road – you either retreat or continue on
One idea was to continue on a path to Derry Lodge, an option that would have allowed me to complete a circuit of the Cairngorm 4000s. But the weather was less than ideal – frequent snow and hail showers would have hampered visability high up and on hearing thunder I decided on a plan B and take the low road, a 27-mile wilderness path to Glen Feshie.
The track starts off well and I noticed a few other walkers plus a game keeper on the opposite path. After White Bridge the terrain turns into proper moor – you get the feeling you are a long way from civilisation as you glance up at distant, snow-capped fells.
I was soon faced with a junction at a ford, a walker was changing into ‘sand shoes’ before he headed on his way to Blair Atholl. The path from here soon deteriorated – I made the mistake of fording Geldie Burn on my way to the ruin of Geldie Lodge. These old buildings seem to have a magnetism that draws you in for a closer look. As I stood among the ruins I realised that I’d made yet another wrong turn – the path onward seemed to peter out so I had to re-ford the burn onto the path that deteriorated further – many sections were little more than boggy streams. Progress was slow with the heavy bike – the front wheel kept sinking and at one point I bent the outer chain ring catching a rock. I managed a repair but effectively lost a third of my gears.
You hear the River Eidart before you see it – a waterfall flows through the deep cut in the landscape, progress from here is over a rickety bridge. A couple of the wooden slats were rotten; I decided to carry the panniers across rather than chance the weight of the whole bike.
The bridge more or less marks the high point of the ride after which progress is more or less all downhill. The change in the landscape is quite marked; the valley becoming much steeper and more wooded, it reminded me a lot of Valsesia in Piemonte.
Serious erosion on the path of the eastern bank of the River Feshie made it necessary to ford the river three times. With the light starting to fade I began looking for a suitable camping spot. Ruigh Aiteachain, my scheduled overnight stop was now on the wrong side of the river and Glenfeshie Lodge was still not open after the lockdown. Because it was a good road I decided to keep going and after passing through a hamlet I found a spot on the river bank as light really was fast fading. Conscious that cows were in the vicinity I crossed over to a dried overflow bed and pitched the tent. This was the first time I’d had the tent out of its bag and though easy to pitch I was cursing that I hadn’t had a least one practice in the garden in the months since I’d bought it.
Forty miles and nearly 11 hours in the saddle it had been the hardest day’s biking ever. After brushing my teeth I crawled into my sleeping bag and sleep quickly followed.

Day 4: Feshiebridge to Loch Doire nan Sgiath 38 miles 3,431ft ascent 11 hours (2 hours in Kingussie) Weather: Max 7.6 Min 0.4 Rain 2mm Wind NNE 4.4mph Castles, lochs, distilleries and dozens of deer
The dawn chorus awoke me just before 6am along with the reassuring sound of raindrops – not to mention the comforting hum of the fast-flowing River Feshie. It was time to break camp.
Packing everything up seemed to take an age, it wasn’t much before I was pedalling again back to the road at Feshiebridge. With a dead phone I made a beeline for Kingcraig but soon found myself pedalling on to Kingussie where I found a cafe to recharge my electronics and myself.
Although polite I found the locals to be a bit standoffish after exchanging the usual initial pleasantries. I resolved to listen to the conversations of others as they came and went; the hot topic seemed to be the coming election and more than one person exclaimed that they had ‘no interest whatsoever in who bought Boris’s curtains’.
At Newtonmore I swapped the old A86 for the B9150 and another cycle path that more or less trekked all the way to Dalwhinnie. From here it was another delightful lochside path along Loch Ericht.

Day 5: Loch Doire nan Sgiath to Fort William 32 miles, 1287ft (4.5 hrs) Weather: Max 8.1 Min 2.8 Rain 1mm Wind NE 4.3mph Glass-smooth lochs, giant pines, empty castles
After a much better overnight camping stop I rode on to Fort William. The path down to Loch Laggan, a gravel track suddenly turns into the smoothest Tarmac road before you reach ‘Kings Grave’, a Scottish castle that looks like something out of a Hammer studios production. There wasn’t a soul around – I was half expecting Klove to suddenly appear at the door.
The path along the southern shore of Loch Laggan offered superb views of snow-capped Creag Meagaidh – clouds of vapour could be seen as the strong spring sunshine evaporated the wintry precipitation that had fallen overnight.
The original plan to proceed to Corrour shooting lodge was abandoned as steep paths beyond effectively blocked my way west. From here it was a straightforward, mostly downhill, onward path into Fort William.
Day 6: Fort William – Observatory Gully, Ben Nevis 30 miles, 5,194ft (11.5 hrs) Weather: Max 8.6 Min -2.1 Rain tr Wind WSW 7.5mph A little skiing at last
After abandoning efforts to go up Aonach Mor – impossible even with half the panniers / weight left in the b&b – the day’s climbing didn’t really start until 3pm from the North Face car park.Lots of ‘you’re mad’ odd looks though with words of encouragement from walkers and climbers on the way up to the CIC hut at 2,231ft.Knackered but with the sight of the snowline just a few hundred feet higher I transferred the skis to the pack, locked the bike and continued on to the snowline, around 2,700ft up Observatory Gully. Ski boots and crampons on at 6pm I went higher to the small buttress at 3,900ft. With one eye on the clock the skis went on and a slide back down lumpy snow. I’d travelled 210 miles and climbed 18,571ft for a ski descent of 1,246ft. Is this the longest ‘walk in’ to a ‘ski tour’ ever?I made it back to Fort William as the last light of the day faded at 9.30pm
Day 7: Fort William – Mallaig: 43 miles, 3,031ft (5 hrs ish) Weather: Max 6.3 Min 2.3 Rain 4mm Wind NE 16.3mph Stormy lochs, rusting boats, Harry Potter steam trains, railway viaducts, Bonnie Prince Charlie and the best wee dram I’ve ever tasted.
I totally underestimated this leg, thinking it would be a plod to the coast. The last fifth turned me directly into the stormy winds – even on declines I seemed to be buffeted back uphill, I had to resort to walking on large sections.
What I thought was the last hill turned out to be the last but three. I cursed my lot out loud and, approaching delirium, convinced myself that Scottish miles must be longer than English miles.
No matter, I arrived in Mallaig and dipped the wheel in the harbour before finding a pub for the best pint and wee dram I’ve ever tasted.
I’d been lucky with the weather though days like this would have made the tour impossible in this timescale.

After a fairly benign week weatherwise I had to cycle into the full fury of this beast
Though the challenge is complete I’m still raising funds for Young Minds, a brilliant charity for our youth who have suffered greatly being cooped up over the past year.
Air pressure is probably the least celebrated meteorological statistic, most probably because unless you’re staring at a barometer all day you can’t ‘see’ it.
High pressure brings mostly fine weather while low pressure usually brings wind and rain – though it is the gradient of the isobars that can measure the impact each system can bring.
Steep falls and rises in pressure bring the most memorable events, in my case the October 1987 storm.
During the next week there will be a notable fall in pressure – but how will it compare with the past recent years? Looking at my own stats, a relatively small but complete set of 9am barometer readings back to May 2013, it does look like it will be notable.
The table below shows the numbers to beat.
As with many of these events the most impactful weather was found in the north of Scotland. The first period coincides with Storm Caroline. The Met Office blog says Caroline brought a max gust of 93mph at Fair Isle and transport disruption and closed schools across the Western Isles.
