Comments on November 2008
Although November ended on a very cold note after some very mild days in the middle of the month, the mean air temperature of 6.5°C was still the 121st highest in 159 years. Nevertheless, the 12-month running mean temperature fell to 9.28°C, the lowest since December 2001. The end of the month saw great contrasts in weather: there was a maximum temperature of 15.6°C on the 27th but a maximum of only 1.5°C on the 30th.  The minimum air temperature of 8.2°C on the 27th was followed only two nights later by a minimum of -5°C! Rainfall was below average for the month, but the 6- and 12-month totals remained well above average. It was the 13th sunniest November since 1882 but the November total (81.1 hours) was exceeded as recently as 2005. 1947 was the sunniest November at Durham with 120 hours.
