November 2015

Weather Report – November 2015

In Plymtree November was just like the rest of the country, generally mild with an often humid south-westerly flow bringing cloudy conditions, unsettled and often windy. However, although there was rainfall on many days during the month amounts were not large. The total rainfall I measured for the month was 72.5mm. The average (1981-2010) at Dunkeswell Airfield is 115.9mm. This means that we received only 63% of the Dunkeswell average. Although South West England and South Wales as a whole received above average rainfall (122%), because the totals were greater over South Wales, together with Plymtree receiving protection from Dartmoor in a south-westerly flow, our total was below average. The total autumn (Sep, Oct and Nov) rainfall I recorded was 178.3mm which compares to an average of 315.1mm at Dunkeswell or 57% of average. The wettest day of November was the 6th with 9.5mm. There were 19 rain days (rainfall ≥ 1mm), which compares to an average of 14.8 days for Dunkeswell, and only 6 days with no measurable rainfall. The highest temperature I recorded during November was 17.0°C on the 6th. The lowest temperature, -3.9°C was recorded on the 23rd. There were only 4 air frosts during the month. It was interesting to note that the maximum temperature (9.4°C) attributed to the 23rd actually occurred at about 0700 on the 24th and the minimum temperature (-3.2°C) for the 24th occurred at 0900 on 23rd. This is because all daily measurements are made at 0900GMT each day and the figures attributed to the previous day apart from minimum temperatures which are recorded against the date they are read. This is standard Met Office practice.

The strongest wind during November occurred in the afternoon of 29th when a gust of 50.1mph was recorded by Pete Draper at Normans Green.
