The climate of the Isles of Scilly (England)
The Scilly Isles are situated south of the tip of Cornwall; about 45 kilometers off the coast. The archipelago consists of 140 uninhabited and 5 inhabited islands: St. Mary’s, Tresco, St. Martin’s, St. Agnes, Gugh and Bryher. There are no high-rise buildings, noisy big bill boards or attraction parks to be found here. The islands are an oasis of peace and quiet. The scenery is splendid here and one of the main attractions. The islands are ideal for long walks and for enjoying the beaches and picture postcard towns. Don’t forget to hire a boat that takes you along the many beautiful islands.
Despite the fact that the archipelago isn’t that big there are large differences in climate. The islands are situated in the warm Gulf Stream. Average temperatures are much higher than on the main land. The Atlantic wind is responsible for strong winds on the islands. It is also responsible for the differences in climate. In the north there are heather moorlands because of the strong winds. This is very different from the south, which is situated on the lee side. Walking through the Abbey Gardens you get the feeling you are in a tropical paradise.

More climate information
Climate figures are very useful but don’t present a general impression of the climate and the eventual weather circumstances within a certain period. The figures don’t 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:

	chance of (very) hot weather	chance of (very) cool weather	chance of long-term precipitation	chance of hurricanes (cyclones)	chance of sunny days	UV-index
