Natural Earth · locator mapGuernsey is a Channel Island with low northern ground and higher land toward the south. Its coast includes beaches, bays and steep cliffs. Small valleys and cultivated land occupy much of the interior.
The southern cliffs contrast with more sheltered northern and eastern shores. The wider Bailiwick includes other islands, each with its own coastal form and degree of isolation. Guernsey should therefore be distinguished from the whole island group it helps administer.
The sea moderates temperatures, bringing mild winters and relatively cool summers. Cloud, rain and changing Atlantic weather are common features.
The surrounding sea moderates temperatures but brings wind and changeable weather. Large tidal changes expose and cover extensive shore areas. Rocky intertidal habitats, coastal grassland and farmland support different communities of plants and animals.

English is the main language of administration and everyday life. Guernésiais, the island’s traditional Norman language, is an important part of its cultural heritage.
French also has historical and ceremonial roles. Guernésiais is closely related to other Norman varieties, rather than being a local accent of English.
Guernsey's connection with the English Crown survived the loss of mainland Normandy in 1204. The islands were occupied by German forces during the Second World War and liberated in 1945. The Bailiwick is a Crown Dependency with its own institutions, not part of the UK.
