The Virgin Islands' climate is subtropical, with temperatures ranging from 26°C to 31°C (79-89°F) in summer to 22°C to 28°C (72-82°C) in winter. Easterly trade winds keep the humidity low, with May and June the stickiest months. Heavy rain is rare except during hurricane season (June-Nov) when most of the annual rainfall of 100mm arrives, though most of it is in the form of brief showers. The last major hurricanes to hit the Virgins, Hurricane Luis and Hurricane Marilyn, occurred within two weeks of each other in September 1995 and caused several billion dollars of damage. Unsurprisingly, there are good deals to be had in hurricane season - November is the best because off-season prices are still in effect, yet the weather is often just as good as in December.
