Today's island-by-island readings are not in this page right now — the forecast feed did not answer when the page was last rebuilt, and the dashboard above fetches them live in your browser instead. The seasonal picture below — water temperature by month, sunrise and sunset, and the Virgin Islands climate questions — does not depend on that feed. See the live radar ↓

December through April is peak season in the Virgin Islands — the dry season with low humidity, warm temperatures (78–84°F), and the calmest seas. February and March offer the most consistently ideal weather. This is also the busiest and most expensive period for travel.
The US and British Virgin Islands have a tropical climate with warm temperatures year-round. Daytime highs average 82–88°F in winter and 88–92°F in summer. Northeast trade winds keep conditions comfortable, especially on windward (eastern) coasts. Annual rainfall averages 40–60 inches, mostly from brief afternoon showers.
Hurricane season in the Virgin Islands runs June 1 through November 30, with peak activity in August and September. Major storms are possible but not guaranteed each year. September 2017's Hurricane Irma and Hurricane Maria caused severe damage. Travel insurance is strongly recommended for trips during this period.
Rain showers in the Virgin Islands are usually brief and pass quickly. Mornings are typically clear, with short showers more common in the afternoon. The wettest months are September through November. Even during the wet season, most days have several hours of sunshine.
Daytime highs in the USVI average 82–84°F (28–29°C) in winter and 88–92°F (31–33°C) in summer. Trade winds keep the heat manageable on most days. Heat index (real-feel temperature) can be several degrees higher in calm conditions.
Sea surface temperatures in the Virgin Islands run from about 79°F (26°C) at their coolest in February to about 86°F (30°C) in September and October — the 2021–2024 average across St. Thomas, St. John, St. Croix, Tortola, Virgin Gorda, Jost Van Dyke and Anegada. The water is warm enough for comfortable swimming and snorkeling year-round without a wetsuit.
The Virgin Islands lie in the trade wind belt and experience steady northeast winds of 10–20 knots for most of the year. Winds are lighter in summer (July–September). The consistent breezes make the USVI and BVI one of the world's premier sailing destinations.
Pack light clothing (shorts, t-shirts, sundresses), swimwear, sunscreen (reef-safe where required), sunglasses, and a light rain jacket for occasional showers. Bring reef-safe sunscreen — some beaches and marine parks require it. A light layer is useful for air-conditioned restaurants and cars.
