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.

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.
