Climate of the Falkland Islands

The climate of the Falkland Islands is cool and temperate, regulated by the large oceans which surround it. The Falkland Islands are located over 480 kilometres (298 mi) from South America, to the north of the Antarctic convergence, where cooler waters from the south mix with warmer waters from the north.

Winds mostly come from the west, creating a difference between the relative levels of precipitation between the eastern islands and the western islands. The total annual rainfall is only about 573.6 mm (23 in). Although snow falls, it does not settle due to the strength of the winds.

The temperature of the islands fluctuates within a narrow band, not reaching higher than 24 °C (75 °F) or lower than −5 °C (23 °F). There are long hours of daylight in the summer, although the actual number of hours of sunlight is limited by cloud cover.

The Falkland Islands have a maritime climate in the transition region between the temperate and subarctic zones (Köppen classifications Cfb and Cfc respectively). The climate is very much influenced by the cool South Atlantic ocean and its northerly Patagonian current. The oceanic climatic type is characterised by both low seasonal and diurnal temperature ranges and no marked wet and dry season while in the sub-arctic zone the average monthly maximum temperature exceeds 10 °C (50 °F) for no more than four months of the year and the average monthly minimum does not drop below −3 °C (27 °F).

In addition to parts of the Falklands, a maritime subarctic climatic zone is found in parts of coastal Iceland, Faroe Islands, northwestern coastal Norway, southern islands of Alaska and parts of the Alaskan Panhandle, the southern tip of South America and mountainous areas of Europe including the Scottish Highlands and southwestern Norway.
