The high season in the BVI is traditionally winter—from December 15 to the week after the St. Thomas carnival, usually the last week in April—when northern weather is at its worst. During this season, you’re guaranteed the most entertainment at resorts and the most people with whom to enjoy it. It’s also the most fashionable, the most expensive, and the most popular time to visit—and most hotels are heavily booked. Saving money isn’t the only reason to visit the BVI in the off-season. Summer is usually one of the prettiest times of the year; the sea is even calmer, and things move at a slower pace (except for the first two weeks of August on when the BVI celebrates the carnival).

The water is clearer for snorkeling and smoother for sailing in the Virgin Islands in May, June, and July.

Climate

Weather in the BVI is a year-round wonder. The average daily temperature is about 80° F, and there isn’t much variation from the coolest to the warmest months. Rainfall averages 40 to 44 inches per year. But in the tropics, rainstorms tend to be sudden and brief, often erupting early in the morning and at dusk.

In May and June what’s known as the Sahara Dust sometimes moves through, making for hazy spring days and spectacular sunsets.

Toward the end of summer, of course, hurricane season begins in earnest, with the first tropical wave passing by in June. Islanders pay close attention to the tropical waves as they form and travel across the Atlantic from Africa. In an old paradox, tropical storms passing by leave behind the sunniest and clearest days you’ll ever see. (And that’s saying something in the land of zero pollution.)

The following are average daily maximum and minimum temperatures for the Virgin Islands.
