The climate of the Orkney Islands (Scotland)
The Orkney Islands are also known as the Orcades. This is a large archipelago off the Scottish north coast. This archipelago consists of approximately 200 islands of which 10% is inhabited. The total population in this archipelago is about 20.000. Most of the inhabitants live in Kirkwall which is the capital of Mainland. The Orkney Islands can either be reached by ferry or by plane. Kirkwall airport has flights to several destinations in the UK. The rest of the inhabited islands can be reached by ferry. On the island of North Ronaldsay there is a type of sheep that is named after this island and only feeds on seaweed.
The Orkney archipelago has a cool moderate sea climate. This climate is remarkably mild and stable for this northerly degree of latitude. This is caused by the influence of the Gulf Stream. The average temperature over a year is 8 degrees Celsius. Between 850 to 940 millimeters of precipitation falls on average per year. This climate is characterized by wind that blows virtually constantly during the summer. During the winter strong winds are not uncommon. On the longest day sun rises at 03:00h and sets at 21:29h; it will not become completely dark during this day. On the Northern Islands this dusk is known as dim suddern. Winter nights are very long. On the shortest day sun rises at 09:05h and sets at 15:16h. At this time of year the aurora borealis can be seen at the northern horizon.

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:
