The climate of theShetland Islands (Scotland)
The Shetland Islands are an archipelago off the Scottish north east coast. Its capital is Lerwick. On this archipelago approximately 22.000 people live of which 18.000 live in the capital on South Mainland. The archipelago consists of approximately 100 islands of which 15 are inhabited. The Shetland Islands can either be reached by ferry or by airplane. Tingwall Airport has several daily flights across the UK. Several ferries sail between the islands. The landscape is very rugged and characterized by the absence of trees. Several bird colonies live on the uninhabited islands together with seals and other sea mammals.
The Shetland Islands have a maritime sub arctic climate with long mild winters and short cold summers. The climate is moderate because of the influence of the warm sea water. During the winter months temperatures will be 5 degrees on average. During the months of March and April temperatures may rise over 10 degrees Celsius. Summers are relatively cold with temperatures around 20 degrees on average. The warmest month on record had an average temperature of 27.2 degrees Celsius. With about 200 rainy days per year precipitation figures are rather high. At any given time during the year snow may fall. November and December are the wettest months. During the summer fog is not uncommon. This is caused by the cooling influence of the sea over southern currents. The Shetland Islands get about 1065 hours of sunshine on a yearly basis. Cloudy days are not uncommon. Sunny days are scarce.

More climate information
Climate figures are very useful but donít present a general impression of the climate and the eventual weather circumstances within a certain period. The figures donít always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
