The averaging period used for the following assessment was 1971-2000.
Mean temperatures were generally above the 1971-2000 normal for October, typically by between 1.0 and 1.5 °C. This was largely due to a very mild last 10 days. Rainfall was below average across most of the UK, with parts of England and Wales recording less than 75% of normal. In contrast it was wetter than average across north-east Scotland, with nearly 175% of normal in Aberdeenshire. Sunshine was generally close to, or somewhat below, normal.
A maximum temperature of 21.2 °C was recorded at Coningsby (Lincolnshire) on 6th. A minimum temperature of -4.0 °C was recorded at Tyndrum (Perthshire) on 17th.
