Wednesday produced the coolest day this month when the thermometer struggled to reach 11.8C during daylight hours, almost 3C below the average. During the evening this lifted to 12.4C, still 2.2C down on the average.
It was a gloomy day with heavy cloud shrouding the tops of the Marlborough Downs producing thick mist with visibility falling in the afternoon as this thickened with visibility dropping to 400m as ‘hill fog’.
The wind was very light all day with the strongest gust registering just 11mph. Not surprisingly, the UV level at 0.6 was the lowest since 15th February.
Overnight, the thermometer stayed at 12.8C, the wind dropped out completely and the fog thickened with visibility falling to 200m.
However, just before 08.00 this morning the ‘hill fog’ began to move with visibility varying from 400m to 1100m.
There was just 1.1mm of precipitation in the past twenty-four hours, bringing the total for October to 12.2mm, being just 14% of the 33-year average for October.
