The countries of the United Kingdom

The total area of the United Kingdom is approximately 245,000 square kilometres (94,600 sq mi) comprising of the island of Great Britain, the northeastern one-sixth of the island of Ireland (Northern Ireland) and smaller islands.^[9] It lies between the North Atlantic Ocean and the North Sea, coming within 35 kilometres (22 mi) of the northwest coast of France, from which it is separated by the English Channel.^[9] Great Britain lies between latitudes 49° and 59° N (the Shetland Islands reach to nearly 61° N), and longitudes 8° W to 2° E. The Royal Greenwich Observatory, near London, is the defining point of the Prime Meridian. When measured directly north-south, Great Britain is a little over 1,100 kilometres (700 mi) in length and is a fraction under 500 kilometres (300 mi) at its widest, but the greatest distance between two points is 1,350 kilometres (840 mi) between Land's End in Cornwall (near Penzance) and John o' Groats in Caithness (near Thurso). Northern Ireland shares a 360-kilometre (224 mi) land boundary with the Republic of Ireland.^[9]

The United Kingdom has a temperate climate, with plentiful rainfall all year round.^[9] The temperature varies with the seasons but seldom drops below −10 °C (14.0 °F) or rises above 35 °C (95 °F). The prevailing wind is from the southwest, bearing frequent spells of mild and wet weather from the Atlantic Ocean.^[9] Eastern parts are most sheltered from this wind and are therefore the driest. Atlantic currents, warmed by the Gulf Stream, bring mild winters, especially in the west, where winters are wet, especially over high ground. Summers are warmest in the south east of England, being closest to the European mainland, and coolest in the north. Snowfall can occur in winter and early spring, though it rarely settles to great depth away from high ground.
