May 2017 & Spring

Weather Report – May and Spring 2017

In Plymtree the predominately dry weather during April, apart from the last day, continued for the first 10 days of May. Then for the next 10 days it turned generally unsettled with rain or showers on most days. The remainder of the month was then mostly dry and it became very warm. During the early hours of the 27th there was an amazing lighting display but very little thunder and only a few spots of rain. The “sheet” lighting (cloud to cloud rather than cloud to ground) was almost continuous and I certainly don’t recall seeing so many lighting flashes in just a short space of time. The total rainfall I measured for the month was 43.9mm. The average (1981-2010) at Dunkeswell Airfield is 72.3mm. This means that we received 61% of the Dunkeswell average. The total spring (Mar, Apr and May) rainfall I recorded was 165.8mm which compares to an average of 227.2mm at Dunkeswell or 73% of average. The wettest day of May was the 16th with 11.5mm. There were only 9 rain days (rainfall ≥ 1mm), which compares to an average of 11.3 days for Dunkeswell. The highest temperature I recorded during May was 26.4°C on the 24th. The lowest temperature, 0.1°C was recorded on the 10th. The strongest wind occurred during the evening of the 13th when a gust of 24.4mph was recorded by Pete Draper at Normans Green.
