SEPTEMBER 2020

The first three weeks of September were dominated by high pressure bringing stable conditions with sunny periods, occasionally beginning overcast but soon clearing. Apart from brief showers on 2nd & 5th (1.2mm & 1.7mm respectively) there was no rain. Winds were light, W-NW until 9th, then swinging round to E-NE.

The daytime temperature was mainly around 20°C but climbed to 23.7°C on 8th. A hotter spell occurred from 13th-16th reaching 24.1°C, 28.6°C, 25.7°C & 25.3°C respectively. The 14th registered the warmest day of the month. Night time temperatures only fell below 10°C on 1st & 2nd and ranged up to 16.5°C on 8th.

The barometer then began to fall sharply and the wind went round to SW on 22nd and increased. Heavy rain fell overnight of 22nd/23rd bringing 8.0mm and continued into 23rd with another 4.8mm. Maximum temperatures fell to between 13.7°C and 18.4°C and nights into single figures.

There was more rain on the nights of 28th & 30th (8.4mm & 12.0mm). This brought the total for September to 36.1mm, 70% of my 25-year average. The total for the year so far is 519.8mm, just 10% above average.

As a whole, September was a very pleasant, warm (1.2°C above average), dry month with plenty of sunshine and light winds.
