In the summer, it can be as hot as 32°C (90°F) but mostly the temperature only reaches 26°C. The average high in London from June through August is around 21°C (70°F) and the average low is around 12°C (51°F)

England

Over England the mean annual temperature at low altitudes varies from about 8.5 °C to 11 °C, with the highest values occurring around or near to the coasts of Cornwall (in the south west).

Winter temperatures average 4.4 °C (40 °F )

Summer temperatures average about 15.6 °C (60 °F ()

The sunniest parts of the United Kingdom are along the south coast of England. Many places along this south coast achieve annual average figures of around 1,750 hours of sunshine. The dullest parts of England are the mountainous areas, with annual average totals of less than 1,000 hours.

Rainfall in England varies widely. The Lake District is the wettest part, with average annual totals exceeding 2,000 mm. However, all of East Anglia, much of the Midlands, eastern and north-eastern England, and parts of the south-east receive less than 700 mm a year.

Facts and Figures:

Highest recorded 38.5 °C at Brogdale, near Faversham in Kent on 10 August 2003.

Lowest recorded -26.1 °C at Newport (Shropshire) on 10 January 1982.

Scotland

Generally, Scotland is more cloudy than England, due mainly to the hilly nature of the terrain and the proximity of low-pressure systems from the Atlantic.

There is a general misconception that the whole of Scotland experiences high rainfall. In fact, rainfall in Scotland varies widely, with a distribution closely related to the topography, ranging from over 3,000 mm per year in the western Highlands to under 800 mm per year near the east coast .

Over Scotland the mean annual air temperature at low altitude ranges from about 7 °C on Shetland, in the far north, to 9 °C on the coasts of Ayrshire and Dumfries and Galloway in the south-west.

Facts and Figures:

Highest recorded 32.9 °C at Greycrook (Scottish Borders) on 9 August 2003.

Lowest recorded -27.2 °C at Braemar (Aberdeenshire) on 11 February 1895 and 10 January 1982. -27 °C was also recorded at Altnaharra (Highland) on 30 December 1995.

Wales

On the whole, Wales is cloudier than England, because of the hilly nature of the terrain and the proximity to the Atlantic.

Rainfall in Wales varies widely, with the highest average annual totals being recorded in the mountainous areas of Snowdonia and the Brecon Beacons, where the yearly fall is comparable with that in the English Lake District or the western Highlands of Scotland. In the east, close to the border with England, annual totals are similar to those over much of the English Midlands. Snowdonia is the wettest part of Wales with average annual totals exceeding 3,000 mm, but coastal areas and the east receive less than 1,000 mm a year.

Over Wales the mean annual temperature at low altitudes varies from about 9.5 °C to 10.5 °C, with the higher values occurring around or near to the coasts.

Facts and Figures:

Highest recorded 35.2°C at Hawarden Bridge (Clwyd) on 2 August 1990.

Lowest recorded -23.3°C at Rhayader (Powys) on 21 January 1940.
