The autumn 2011 United Kingdom heat wave was a period of unseasonably warm weather which arrived towards the end of September 2011 and continued into October.

Synopsis

Temperatures in most parts of the United Kingdom began to rise on 25 September, reaching 23 °C in some areas. [2] The warm weather stayed consistent over the next few days and reached 27 °C at Saint Helier in Jersey on 28 September. [3] Temperatures continued to rise and the temperatures recorded on 29 September exceeded those peaked in Costa del Sol, Turkey and Mexico that day at 29 °C in Lincolnshire. [4] This also broke the UK's record high for that day of the year, with 27 °C having been recorded in York on 29 September 1985. [5]

Jersey British Crown Dependency in the Channel Islands

Jersey, officially the Bailiwick of Jersey, is a Crown dependency located near the coast of Normandy, France.

Costa del Sol coastal area in Andalusia, Spain

The Costa del Sol is a region in the south of Spain, in the autonomous community of Andalusia, comprising the coastal towns and communities along the coastline of the Province of Málaga.

The month of October began with a southerly airstream resulting in some exceptionally high temperatures, reaching 25–28 °C throughout England and Wales. [6] The first of October brought the highest temperatures of the heat wave with 29.9 °C recorded in Gravesend, Kent, the highest ever recorded in the United Kingdom for October, beating the previous October record of 29.4 °C which was set in 1985 in March in Cambridgeshire. [1] The new record also made the first day of October the third-warmest of 2011, although in several places (such as Sennybridge in Powys), 1 October was the hottest day of the year. [7] The annual high temperature was broken in certain places in the west and north. Throughout the month, mild westerly and southerly airstreams brought rain to north-western UK, and further relatively warm and dry days in the south. [6] The Central England Temperature for October was 13.02 °C, almost 2 °C above the 1971–2000 average, and was the warmest October since 2006 and the eighth-warmest in 100 years. There was a marked contrast in rainfall, with amounts ranging from well below average over East Anglia and south-east England to well above in Northern Ireland and western Scotland. Subsequently, sunshine amounts also varied accordingly, from well below normal over Northern Ireland and western Scotland to well above in East Anglia. [6] However, a cold front from the remnants of Hurricane Ophelia brought much cooler air across the whole of the country. [8] [9]

Effects
