Weather

The Tradewinds (the Easterlies) dominate the weather in the Virgin Islands, blowing east to west across the tropical Atlantic. The winter tends to bring stronger winds and less rain, and the summer tends to bring more rain and lighter winds.

In winter, cold fronts moving off the continent sometimes bring the Christmas winds down from the north. The fronts do not bring cold air as far south as the Virgin Islands, but they can create large waves breaking on the north shore beaches. Use extreme caution entering the water during such conditions, and heed posted warnings and advice from park staff.

In summer, tropical storms or hurricanes occasionally approach from the east and south. More commonly, tropical waves bring clouds of African dust across the Virgin Islands.
