Comments on November 2022
Despite three cold days at the end of the month, this was still the 5th mildest November on record, a touch warmer than last year but just a bit cooler than November 2020.
The night of 11th November is the warmest on record for the month (14.4 °C), easily beating the previous record-holder, 11th November 2015 (13.7 °C); only three days were warmer this month! That night was followed by a maximum of 16.9 °C, the 9th warmest November day since 1843. There was the 3rd highest mean grass minimum for November since 1874, exceeded only in 2011 and 2021, with 7 fewer ground frosts than usual. It was a wet month and, whilst nowhere near as the record holder 1965 (186.1 mm), it was nevertheless the equal 19th wettest November since 1850. Not surprisingly, it was a dull month, the equal 19th dullest November since 1880.
For autumn as a whole, this was the fourth warmest on record (11.3 °C), beaten only in 2011, 2021 and 2006. The mean maximum temperature (14,5 °C) is the 5th highest on record whilst the mean minimum (8.1 °C) is 2nd equal highest. There were just 4 air frosts, 7 fewer than normal and just 5 ground frosts, 12 fewer than normal, the 2nd lowest autumn total on record. The minimum on the night of 11th November is the equal 4th highest for autumn, remarkable for so late in the year. It was a wet autumn (292.6 mm), 150% of the average, the 11th wettest autumn on record. There were 65 rain days, the 5th highest autumn total. The sunshine total (298.4 hours) was just 24 minutes below the average!
