The Coronation Day on Saturday was an appalling day with persistent rain for 11 hours amounting to 13.2mm as a depression, with associated weather fronts, travelled along the English Channel and Southern England. That took the monthly total to 23.1mm, after just six days, when the average is 60.5mm. Not only that, the thick, low cloud and lack of sunshine meant a very cool day with the thermometer not rising above 13.9C, which was 3.2C below the average. The UV level of 2.1 was in the ‘Low’ category and the lowest since 29th March.
The overnight minimum was 10.5C at 01.10 early Sunday. This was 4.7C above average thanks to the blanket of cloud retaining any warmth from the previous day.
Sunday dawned dull and gloomy with fog limiting visibility to 400m at 07.00, easing considerably by 08.00, but mist still draping the tops of the Marlborough Downs and the trees in Savernake Forest. Not surprisingly, the humidity was 99% at 08.00, the most humid start to a day since 29th March.
