I didn't manage to log weather statistics this month, although I will say that it's quite interesting (although not that unusual) that Tulloch Bridge in the Scottish Highlands reached -4.2'C this early in the game.

A very average month, but still the coolest September since 2002. At 117% of normal rainfall, it was the first month to be wetter than average since February.

The first few days were dry and sunny with average temperatures by day but cooler nights. It then turned much wetter in the second week with rain falling on every day from the 6th-16th. It was much warmer however, with temperatures into the low 20s on the 9th, 10th and 11th. The warmest day was the 11th, when it reached 21.8C. Sunshine levels were at a premium though, due to the airmass being of a tropical maritime origin.

It then turned much cooler on the 17th, as flow turned to the north-west. Single-figure minima made a return and the 17th was a cool day, with a maximum of just 13.8°C. It became briefly warmer again on 21st and 22nd, reaching 21.1°C and 21.7°C before cooling down once again. At first the flow was northerly, giving cool days and further single figure minima but then the wind turned to the north-east, providing four days of overcast skies, persistent rain and temperatures between 10-14°C by day and night. The sunshine returned for the final two days of the month.

  • Temperatures into heatwave territory and no rain

    Some parts of the UK could qualify for heatwave conditions later this week and it's not the usual suspects. No rain as water levels decline and how are the evening skies for LanuchAmerica viewing? Watch the video here

    High pressure continues to dominate our weather until at least early next week, with most staying dry and fine. The warm conditions will spread north, and the highest temperatures will transfer to the west as the high moves east and eventually over Scandinavia. Read the full update here
