At the start of September the weather was changeable with high pressure to the south and a west to south-westerly airflow over the UK. The unsettled regime continued for the first five days, but southerly incursions brought hot and humid weather, especially to the south-east, on the 7th and 13th-15th, separated by a wet spell on the 8th-10th. The 13th saw the highest September temperatures since 1911, but at the same time there were widespread thunderstorms in the west. The second half was changeable with frequent frontal systems interspersed with brief fine interludes, but temperatures generally remained above the seasonal average.
The provisional UK mean temperature was 14.6 °C, which is 2.0 °C above the 1981-2010 long-term average, making it the equal second warmest September in a series from 1910. The positive temperature anomaly was generally higher by night than by day, especially in the west. Rainfall was 103% of average, and it was a dry month in most counties bordering the North Sea, but a wet month in many western counties. Sunshine was 95% of average, and was mostly near or rather below average except in East Anglia, north-east England and Aberdeenshire.
The UK monthly extremes were as follows: A maximum temperature of 34.4 °C was recorded at Gravesend (Kent) on the 13th. A minimum temperature of 0.1 °C was recorded at Katesbridge (County Down) on the 22nd, and at Aboyne (Aberdeenshire) on the 26th. In the 24 hours ending at 0900 GMT on the 12th, 92.4 mm of rain fell at Skye Alltdearg House (Inverness-shire). A wind gust of 62 knots (71 mph) was recorded at Loch Glascarnoch (Ross & Cromarty) on the 27th.
