Sunshine Information for the UK
The sunniest parts of the United Kingdom are along the south coast of England. This is largely because the formation of convective (cumulus) cloud takes place over land and skies over the sea remain cloud-free. 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.

Mean daily sunshine figures reach a maximum in May or June, and are at their lowest in December. The key factor is, of course, the variation in the length of the day through the year, but wind and cloud play their part as well.

Facts and figures
Maximum duration in a month: 383.9 hours at Eastbourne (East Sussex) in July 1911.

Minimum duration in a month: 0.0 hours at Westminster (Greater London) in December 1890.


Rainfall Information for the UK
Rainfall in England varies widely. The Lake District is the wettest part, with average annual totals exceeding 2,000 mm (this is comparable with that in the western Highlands of Scotland). The Pennines and the moors of south-west England are almost as wet. 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.

Typically, it rains on about one day in three in England, perhaps somewhat more often in winter, though long, dry spells occur in most years.

Near the south coast there is an appreciable summer minimum and winter maximum of rainfall, with totals in July barely half those in January; western, northern and eastern coasts are more likely to see the driest month in spring and the wettest in late autumn. Inland, parts of the Midlands experience a summer rainfall maximum, which is a reflection of the higher frequency of thunderstorms in the more central and south-eastern parts of England. For example, at London and Birmingham, thunder occurs on an average of 15 days a year, but in the west and north-west the frequency declines to around eight days per year.

Facts and figures
Maximum in a day (09-09 UTC): 279 mm at Martinstown (Dorset) on 18 July 1955.

Temperature Information for the UK
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. The mean annual temperature decreases by approximately 0.5 °C for each 100 m increase in height so that, for example, Great Dun Fell in Cumbria (at 857 m) has an annual mean temperature of about 4 °C.

To a very large extent, winter temperature in the British Isles in influenced by the surface temperatures of the surrounding sea, which reach their lowest values in late February or early March. Around the coasts February is thus normally the coldest month, but inland there is little to choose between January and February as the coldest month.

The coldest nights are those on which there is little wind, skies are clear, and there is a covering of snow on the ground; the lowest temperatures occur away from the moderating influence of the sea, on the floors of inland valleys into which the cold air drains. It was under such conditions that the temperature fell to -26.1 °C, the lowest ever recorded in England, at Newport in Shropshire on 10 January 1982. Coastal areas do not experience such cold nights; as an example the lowest temperature ever recorded at Plymouth in Devon is -8.8 °C on 2 January 1979. At the opposite extreme, the highest winter temperatures are apt to occur in the lee of high ground. These high winter temperatures (up to 16 °C on rare occasions) occur when a moist south to south-westerly airflow warms up downwind after crossing mountains, an effect knows as the föhn after its more dramatic manifestations in the Alps.

July is normally the warmest month in England, and the highest temperatures of all have occurred in central districts furthest away from the cooling influence of the Atlantic. The highest temperature ever recorded in England is 38.5 °C at Brogdale, near Faversham in Kent on 10 August 2003, which is also the highest temperature ever recorded anywhere in the United Kingdom.

Facts and figures
Air temperature (measured under standard conditions at 1.25 m above the ground).

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.
