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.
Compiling a list of sunless, rainy days revealed some interesting spells of wet weather – the most miserable runs of June days in the capital since 1959.
First up was a three-day spell starting on June 25, 1974. Some 34.3mm of rain was recorded.
Next was a three-day spell starting on June 23, 1991. Some 26.3mm of rain was recorded.
Another three-day spell started on June 25, 1997. Some 36.2mm of rain was recorded.
Finally, and most recently, a two-day spell this month that began on June 17th. Some 28mm of rain was recorded.
The above spells all happened around the date of the ‘June monsoon’ singularity which has a probability of 77 per cent. Though the fact that these occurred 47 years, 30 years and 24 years ago shows that these extreme cases happen a lot less than three years in every four the singularity would suggest.
Comparing the current Northern Hemisphere pattern with 1974 suggests that while there’s just as much heat around at 850mb as there was 47 years ago, including an extreme heatwave over some Nordic countries, the air above Greenland appears colder.
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.
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.
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
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.
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.
Old castle-like lodges
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.
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.
Of course what goes down also comes up and pressure rises can be even more notable. In February 2016 the pressure rose 50mb in just three days, a week or so after Storm Imogen.
According to the Met Office FAX charts the 9am pressure in London on March 11th will be around 988mb, which would represent a fall of 48.6mb from 9am on March 6th.
Attention on the bright meteor seen over the UK earlier this week got me thinking about the meteors frequently mentioned in Luke Howard’s Climate of London volumes.
Howard had a keen interest in all things atmospheric, not least this celestial phenomena. Many of his personal accounts are mentioned over a period of a decade or so including accounts of meteors overseas.
The last three months in east London, considering sunshine, have been the dullest for 10 years. Despite the sunny end to February just 123 hours of sun have been recorded, just under 74 per cent of the seasonal average.
With little sun, rainfall well above average, temperatures best described as average and the endless lockdown it is no wonder things felt so grim.
A couple of years ago, inspired by the blogger XMetman, I devised my own ‘grim index’ to try to rank how each winter ‘felt’.
Using the same criteria, and assuming that most people welcome sunshine, it can be seen that since the least grim winter of 2007-08, the season, after a blip in 2018-19, has been growing steadily worse.
The grimmest winter, considering statistics back to 1881, was, ironically, the 1978-79 ‘Winter of Discontent’ when, again ironically, ‘Sunny Jim’ Callaghan was in Downing Street as widespread strikes coincided with the coldest winter for 16 years.
On looking at the Top 20 of grim winters it is striking how most coincide with depressing world events, the Great War, World War 2 and the Spanish Flu pandemic.
