The effect of the change in wind direction to southwest brought a dramatic change to our weather on Monday. The very moist Atlantic air, having travelled over thousands of miles of sea, raised the humidity level and brought the first rain for a week. The very light drizzle occurred very briefly during mid-morning but set in for several intermittent hours mid-afternoon producing 1.8mm of precipitation. This brought the monthly rainfall to 18.0mm when the 38-year average is 66.9mm.
The persistent low cloud meant minimal brightness and a much cooler day with a maximum of 19.9C being 1.2C below the average. Conversely, the cloud meant a very mild night with the minimum not dropping below the temperature at 08.00 on Monday morning of 15.2C being 3.5C above the average. It was the coolest day since 2nd July (18.2C).
Tuesday arrived initially with total cloud cover but just before 08.00 breaks in the cloud allowed brief sunny intervals that raised the temperature to 17.8C at 08.00. The humidity at 08.00 read 91%.
