The averaging period used for the following assessment was 1981-2010.
The image below is from the NERC Satellite Receiving Station, Dundee University. This shows a deep area of low pressure in mid-Atlantic on 14 October 2014, leading to a mild south-westerly flow across the UK (at top right of image) around mid-month.
The analysis chart on 14 October 2014 also shows this deep area of low pressure in mid-Atlantic.
October came as quite a contrast to the previous month, as the weather became unsettled and wet by the 3rd and remained so through the majority of the month, interspersed with only short periods of drier weather. With winds frequently from the south, this October was another month with well above average temperatures, and notably warm on the 31st.
The UK mean temperature was 11.1 °C, which is 1.6 °C above the 1981-2010 long-term average. This made it the equal- tenth warmest October for the UK in a series since 1910, and only marginally cooler than the Octobers of 2011 and 2013. Rainfall was above average in some areas, particularly across much of Scotland and Cumbria, with double the long-term average around the Solway Firth and the Isle of Man. The overall UK rainfall was 125% of average. Sunshine was rather below normal overall, with a UK figure of 90%, and the sunniest areas relative to average were Northern Ireland, the Western Isles of Scotland and the east coast of England.
A maximum temperature of 23.6 °C was recorded at Gravesend (Kent) and at Kew Gardens (Greater London) on the 31st. A minimum temperature of -3.7 °C was recorded at Altnaharra (Sutherland) on the 13th. In the 24 hours ending at 0900 GMT on the 4th, 126.6 mm of rain fell at Honister Pass (Cumbria). A wind gust of 84 mph was recorded at South Uist (Western Isles) on the 6th.
The month was generally unsettled, with various events causing impacts in certain areas. One particularly active weather system crossed the UK during the night of 5th/6th, with strong winds and large amounts of rainfall.
Persistent rain moved north into southern England and the Midlands on the evening of Sunday 12th and into Monday 13th, with some heavy showery bursts, enough to cause localised flooding.
The remnants of Hurricane Gonzalo blew into the UK on the night of the 20th/21st, with warnings of disruption due to strong winds as well as localised heavy rainfall, most especially over the northern half of the UK. With trees still in leaf some disruption and damage was caused by falling trees and a woman was killed by a falling tree in Knightsbridge (London).
Beginning on the 25th, there was heavy frontal rainfall over much of western Scotland, giving some unusually high totals over a three-day period with 200 mm in some places during this time. There were consequent concerns over flooding leading to an Amber warning for the 25th, and some disruption caused by landslides.
England diary of highlights
The month was predominantly unsettled, with strong winds and rain a recurring feature, but these winds were generally from a southerly direction so it was mild, especially in the second half.

Sunshine amounts were below average for central and western areas, with an overall figure of 90% of average.
