Since the Met Office introduced its system of naming storms at the beginning of the autumn season in 2015 the effects felt in the capital have been fairly limited.
Introduced partly in response to the devastation caused by the St Jude Storm in October 2013 every wind storm since has failed to live up to the hype, at least at a local scale.
Of course many storms have caused major disruption elsewhere, not least Storm Desmond, floods from which devastated Glenridding in the Lake District.
But closer to home many of these storms have been marked simply by a higher than average ‘wind run’, the number of revolutions of this weather station’s anemometer.
The windiest days in this locality coincided with Storms Gertrude, Fionn and Erik but these were minnows compared with St Jude and the most recent devastating storm in living memory, the Great Storm of 1987.
The graphs below also highlight the ongoing problem of naming storms in that some of the windiest days in this area occurred when there was no named storm.
The windiest day in the dataset was June 6th 2017 when a low pressure system saw Force 9 winds recorded in the Channel. Locally the day was very blustery and trees that were in full leaf were blown down.
Earlier this winter there were many reports on how good snowfall had been in Austria. But on closer inspection it was clear that the weather pattern at that time only favoured certain resorts.
In contrast with last year the totals I’ve used in my cross section of the range don’t look that exciting; Bourg-St-Maurice, the jumping off point for Savoie resorts including Les Arcs and Val d’Isere, has recorded 96mm of precipitation this season, in stark contrast to the 433mm it recorded last season between Christmas Day and February 5th.
In Switzerland Arosa, a resort well placed to pick up snow from any direction, has recorded the same this season as last. Totals in Davos are well down on last season. Similarly San Bernardino has recorded about half the amount of precipitation than it did last season. Its location toward the southern side of the range has been sheltered from the prevailing winds this year. That said it did enjoy a big dump last week.
Going further south and east St Vallentin in Italy has recorded about a third what it did at this stage last season.
Mean temperatures overall are about 2C to 3C lower than they were last season.
It is 21 years ago this month that London and most of the southern half of the UK experienced a remarkably warm spell of weather during what had been a mild winter.
The spell, which saw the record warmest February day on the 13th (19.7C), satisfies the Met Office’s old criteria of a heatwave whereby the maximum temperature is 5C or more above average for five consecutive days.
While these spells are fairly common in summer they are very rare during a meteorological winter. During the last 60 years the only other periods to have experienced a heatwave in winter are December 1966 and 2015.
Weather charts for this week look remarkably similar though, according to the latest forecasts, values will be nothing like they were in 1998.
During a miserably cold and wet stroll around the golf course in Wanstead Park I happened upon the remains of Wanstead House – basically a deep excavation where the basement and kitchens once were.
As a freezing cold mixture of rain, sleet and snow fell, gradually thawing the remnants of last night’s snow, I wondered what the weather was like when this magnificent building last stood. Luke Howard’s entry in The Climate of London revealed that the weather on this day 200 years ago was remarkably similar.

As I stood and tried to imagine what the house must have looked like it occurred to me that 200 years is a mere blip in time in the history of the Earth. People come and go, buildings rise and fall but the weather goes on and on.
* There’s a fascinating extract on Wanstead from James Dugdale’s The New
British Traveller (1819) that you can find here.

My winter forecast went a bit awry in December – I predicted a mean of +0.8C, the outcome was +1.7C. January has been much better, I predicted -1.2C, the outcome is -1.1C! Also… “And another cold spell end of January into the first week of February?”
For February I predicted a mean of -1.7C. The current pattern to continue and signs on the EC of a more robust cold spell with air supplied by a Scandinavian high?
