Weather Report – December 2016 and Review 2016
In Plymtree December was a complete contrast to the wet November. The dry weather which began in the last week of November continued to dominate for much of the month and even when rainfall did occur amounts were generally small. There were no days when totals exceeded 10mm.The total rainfall I measured for the month was only 19.8mm. The average (1981-2010) at Dunkeswell Airfield is 121.2mm. This means that we received only 16% of the Dunkeswell average. The wettest day of December was the 12th with only5.5mm. There were only 8 rain days (rainfall ≥ 1mm), which compares to an average of 14.9 days for Dunkeswell. Fog was persistent and freezing at the start and end of the month. The highest temperature I recorded during December was 14.3°C on the 8th. The lowest temperature, -6.7°C was recorded on the 1st. It was interesting to note that the maximum temperature (8.6°C) attributed to the 20th actually occurred in the early hours of the 21st (0400) and the minimum temperature (1.7°C) attributed to the 21st actually occurred late afternoon on the 20th (1700). As mentioned before, 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 World Meteorological Organisation (WMO) practice.
My total rainfall for 2016 was 806.2mm, which compares to an average of 1065.3mm for Dunkeswell or 76%. January, February, March, June and November were the only months that had rainfall totals above the Dunkeswell average. The drier than average 2016 followed on from the drier than average 2015 when I recorded a total of 862.4mm or 81% of the Dunkeswell average. The highest daily rainfall total was recorded on the 19th November when 46.0mm fell. The highest temperature of 2016 was 30.8°C recorded on the 19th July and the lowest -7.2°C recorded on 16th February. The strongest wind recorded by Pete Draper during 2016 was overnight on the 20th November when a gust of 38.7mph was recorded during the passage of storm Angus. My maximum wind speed was 39.8mph on 9th March.
[The difference arises because my wind speed is measured at a height of about 6' in the shelter of my back garden and Pete’s on the roof of his house and exposed to the elements].
