British Virgin Islands climate overview

The Dutch and Spanish had previously settled this collection of volcanic islands in the Caribbean, before it became a British Territory in the late seventeenth century.

Today the British Virgin Islands, which lie about 80 kilometres (50 miles) to the east of Puerto Rico, govern their own internal affairs while remaining a British dependency. The economy relies mainly on the financial services industry, and on tourism.

The main island of Tortola is home to 75% of the population while the majority of the other 55 islands and cays are largely uninhabited. The islands have seemingly unlimited brochure-perfect beaches with white sands. The government keeps a close check on the tourist industry to ensure that no area becomes overdeveloped and crowded. As a result there is an abundance of idyllic deserted coastline.

The islands are characterised by secluded bays and coves, making them popular with boating enthusiasts who can hop from one deserted coral cay to the next. The islands' interiors are largely unspoilt with much of the indigenous dense sub-tropical vegetation remaining intact. On the whole the landscape consists of undulating hills, but some areas and a few islands, notably Anegada, are flat.

The British Virgin Islands have a tropical climate with warm to hot daytime temperatures throughout the year that vary by only a few degrees from month to month.

Rainfall is mainly concentrated in the months from the end of June to the end of November with a very short 'winter' dry season that runs from February to April. This is also the sunniest time of the year, broken only by a few afternoon clouds and occasional showers. However even during the peak rainy season, from September to November, when rain falls most afternoons, there is still plenty of sunshine.

Like most of the islands in the Northern Caribbean, The British Virgin Islands lie directly in the track of Atlantic hurricanes travelling from the centre of the Atlantic towards Florida and the Gulf of Mexico. The risk of a hurricane striking is greatest from July to October.
