The averaging period used for the following assessment was 1971-2000.
The first few days were unsettled over most of the UK with copious amounts of rainfall, but pressure then built from the east to give more settled weather and some warm days. For about 10 days from mid-month it was then colder with northerly winds and some very low overnight temperatures. In the last week, frontal systems from the west resumed their influence bringing much milder air and rain at times. Overall, temperatures were close to normal. Rainfall was also close to normal in many areas, but it was drier than average in the west. It was a sunny month, especially in the west. It was the equal-sunniest October on record in Wales (shared with October 1994).
A maximum temperature of 23.1 °C was recorded at Chivenor (Devon) on 8th. Levens Hall (Cumbria) and Sennybridge (Powys) both had minimum temperatures of -6.6 °C early on 25th. Alltdearg House (near Sligachan, Isle of Skye) recorded 105.0 mm of rainfall in the 24 hours ending 0900 on 29th. A wind gust of 72 mph was measured at Capel Curig (Conwy) on 29th.
