As noted earlier, November has been an unusually mild one in the UK. The Met Office summarise:
November was a generally mild month with an often humid south-westerly flow bringing cloudy conditions. It was dry and exceptionally warm during the first few days, with record-breaking temperatures locally, but the rest of the month was unsettled and often windy, and the autumn storms ‘Abigail’, ‘Barney’ and ‘Clodagh’ all caused some disruption. There was a notable absence of frost apart from during a brief cold snap from the 21st to 23rd which brought some snow to northern and eastern Britain, especially on high ground, and there was also some snow in Scotland near the end of the month.
Given the meteorological set up for nearly the while of the month. there should be no surprise that it has also been a wet month, particularly given the various “storms” that have passed our way.
However, as the England & Wales Precipitation Series shows, November was by no means an exceptional month. In the Series which goes back to 1766, last month ranked only 51st wettest with 126.2mm, against the long term mean of 94mm.
The wettest November on record was in 1852 with 202.5mm, while the driest was in 1945, when just 17mm fell.
In terms of the year as a whole, it looks like this year will end up slightly wetter than average, ranking around 100th wettest.
This chart shows as well as any just how variable the weather can be in the UK. If there are any long term trends in November rainfall, whatever the cause, they are so small as to be totally swamped by natural variability.
