South Georgia and South Sandwich Islands climate overview

South Georgia and the South Sandwich Islands lie isolated and exposed in the Southern Atlantic Ocean to the southeast of the Falkland Islands. After their discovery over 300 years ago, the British set up a now-abandoned whaling station on South Georgia. Today, the island's inhabitants consist of just a handful of scientists and massive colonies of penguins and seals, while thousands of albatross circle overhead. The South Sandwich Islands are uninhabited.

South Georgia is mountainous with two ranges, the Allardyce and Salvesen forming the backbone of the island. The northwest is low compared with the southeast where mountains plunge almost vertically into Drygalski Fjord creating spectacular sea cliffs. Over half the mountain peaks, many with jagged pinnacles, are permanently snow-covered, and there are numerous glaciers many of which calf directly into the sea. Vegetation is found only along the coasts where hardy tussock grass, lichen, and mosses cling to survival.

The South Sandwich Islands are a volcanic chain to the south-east of South Georgia. There are 11 main islands, some of which are still volcanically active. All are largely covered in permanent snow and ice with very little vegetation.

The climate is harsh with plenty of cloud and rain. Because of its relatively northerly position and being surrounded by a large ocean, South Georgia escapes the extremes that are experienced further south in Antarctica. The temperature is usually just above or just below freezing. Rain can fall throughout the year, turning to snow during the winter everywhere, and over higher ground during the summer.

The combination of strong westerly winds and cold temperatures makes for a high wind chill although occasional comfortable temperatures are possible during the long summer days. The sea sometimes freezes in sheltered bays in winter. Conditions in the South Sandwich Islands are similar but colder.
