Weather review of November 2020
A mild but otherwise average November
It turned out to be a fairly ordinary November, mostly around average for the time of year. The generally warmer than average trend of the year as a whole continued, however, with the third warmest average daily maximum temperature over the 36 years of records, the third warmest mean temperature, and the 6th warmest average daily minimum. Top temperature of the month was 16.7°C on the 1st, our sixth warmest maximum, and the lowest of the month was 0.2°C on the 27th. This was the twelfth time out of our 36 years that November temperatures did not fall to freezing or below, so the month passed with a couple of grass frosts but no air frost.
Rainfall at 60.8mm was almost spot on the long term average for November, and the highest recorded wind gust was 25mph on the 2nd, or force 6 on the Beaufort scale, fairly modest for November. No major storms this month!
Past barometric pressure records are less comprehensive: we have daily readings taken at 0900 each morning for the period 2003-2013. Now we record air pressure every five minutes and so know the maximum and minimum values reached each day. On that basis, the maximum of 1041.2mb on 5th is the highest recorded to date for November, and the average pressure for the month was the second highest recorded.
