Climate of The United States Virgin Islands
Country climate guideThe United States Virgin Islands are a group of about 50 islands and cays in the northern Caribbean, sitting east of Puerto Rico and to the south of the usual track of North Atlantic storms. Because they are low, warm and surrounded by water, the climate is tropical and maritime with almost no seasonal variation in temperature. What changes through the year is the rain and the wind: a long dry season under the trade winds, a wetter season in late summer, and the possibility of hurricanes in autumn.
Main climate types
The islands carry a tropical savanna climate with a distinct dry season in the cooler months, bordering on the arid grade on the driest, most exposed low ground such as the eastern tip of Saint John and the western end of Saint Thomas. There is no mountain strong enough to make a permanent rainforest, but the eastern hills of Saint John, which catch the trade winds, are markedly wetter and greener than the leeward south shores of Saint Thomas.
Temperatures
Temperatures are warm in every month. Saint Thomas averages about 25 °C in January and about 27 °C in July, with daytime highs typically near 29 °C to 30 °C. Nights stay mild, around 22 °C, and the constant onshore breeze makes the heat feel less than it is. Water temperatures remain comfortable for swimming throughout the year, and the same applies to the smaller settlements of Saint John and the coral beaches of Saint Croix.
Rainfall
Annual rainfall is roughly 1,000 mm to 1,200 mm in most settled places, rising to over 1,500 mm on the eastern hills of Saint John. The dry season runs from about December to May and is the sunniest time, while the wet season from June to November brings most of the rain, usually as short afternoon showers rather than all-day rain. Humidity stays high throughout, and squalls can arrive very suddenly, especially in late summer.
When to go
The dry season, from January to April, is the most reliable for beach weather and for the ferry links between the islands. Hurricane and tropical storm activity runs from June to November, with the greatest risk in September, and this is the main thing to watch when planning.
