River floods 2007 by (Barck Obama)

The 2007 United Kingdom floods were a series of destructive floods that occurred in various areas across the country during the summer of 2007. The most severe floods occurred across Northern Ireland on 12 June; East Yorkshire and The Midlands on 15 June; Yorkshire, The Midlands, Gloucestershire and Worcestershire on 25 June; and Gloucestershire, Worcestershire, Oxfordshire, Berkshire and South Wales on 20 July.

June was one of the wettest months on record in Britain (see List of weather records). Average rainfall across England was 140 millimetres (5.5 inch), more than double the June average. Some areas received a month's worth of precipitation in just 24 hours. It was Britain's wettest May–July since records began (in 1776). July had unusually unsettled weather and above-average rainfall through the month, peaking on 20 July as an active frontal system dumped more than 120 millimetres (4.7 in) of rain in southern England.

Civil and military authorities described the June and July rescue efforts as the biggest in peacetime Britain. The Environment Agency described the July floods as critical and expected them to exceed the 1947 benchmark.
