At the start of September, north-westerly winds brought cool and showery weather to the UK. After this, the weather was dominated by high pressure from the 5th until the 11th and again from the 25th onwards, which mostly brought dry weather with plenty of sunshine, especially near the end of the month. However, the weather was rather changeable from the 12th to the 24th, and despite the two fine spells, it was a generally cool month. The fine spell during the last few days brought warm days but also some notably cool nights.
The provisional UK mean temperature was 11.9 °C, which is 0.8 °C below the 1981-2010 long-term average. It was coldest relative to average across East Anglia and south-east England, but parts of north and north-west Scotland were slightly warmer than average. It was a very dry month in western Scotland and north-west England, with less than a third of the normal rainfall in many locations, but rainfall was near or slightly above average in parts of south-east England. September was a sunny month over most of the UK, especially so in western Scotland, but sunshine totals were below average for Orkney and Shetland.
The UK monthly extremes were as follows: A maximum temperature of 24.0 °C was recorded at Braemar (Aberdeenshire) on the 30th, and a minimum temperature of -1.3 °C was recorded at Braemar (Aberdeenshire), also on the 30th. In the 24 hours ending at 0900 GMT on the 15th, 53.6 mm of rain fell at Milford Haven, Pembrokeshire. A wind gust of 78 mph was recorded at Needles Old Battery (Isle of Wight) on the 15th.
