UK last month

September 2026

September was an unsettled month for the UK with periods of wet and windy weather. However, temperatures were consistently above average, resulting in the joint fourth warmest September on record for the UK. The UK was in a generally westerly flow for most of the month, with low pressure exerting its influence and sending frontal systems with wet and windy weather across the country. The north was particularly wet, with Scotland and Northern Ireland seeing heavy downpours and ending the month with overall rainfall amounts a third above the average. Southern areas were also impacted by rain from frontal systems, but the weather was in general more settled than in northern areas, and England ended the month with below average rainfall again.

It was a mild month for the UK, with the mean temperature 1.6°C above the 1991-2020 long-term average. As well as the UK’s joint fourth warmest September on record, it was England’s third warmest, Northern Ireland’s fourth warmest, and Wales’s joint sixth warmest. Scotland experienced above average temperatures but was just outside its top 10 warmest Septembers. Minimum temperatures were particularly high, with Northern Ireland recording its joint highest September minimum temperatures and the UK its joint fourth highest. Rainfall for the UK was around average (104% of the long-term average), but as often happens there was strong regional variation. Scotland and Northern Ireland both saw a third more rainfall than typical (137% and 135% of average, respectively), while England saw barely two thirds of the average rainfall (65%). Southern England was particularly dry, although no records were broken. Sunshine hours were also around average for September for the UK (98% of average), although Northern Ireland was a bit duller (81%).

The UK provisional monthly extremes were as follows: A maximum temperature of 28.9°C was recorded at Felsham (Suffolk) on the 6^th. A minimum temperature of -1.1°C was recorded at Braemar No 2 (Aberdeenshire) on the 29^th. In the 24 hours ending at 0900 UTC on the 13^th, 60.6mm of rain fell at Dinas Resr (Dyfed). A wind gust of 60 knots (69 mph) was recorded at South Uist Range (Western Isles) on the 29^th.
