Between December and February is the best time to go to St. Thomas. Temperatures are pleasant, averaging 79? (26?). December can see some rain, mainly in the form of short, sharp late afternoon showers as humidity builds up, but this decreases through January and February.

The best time to visit St. Thomas in the U.S. Virgin Islands is from December to March. During these months, the island enjoys its "peak" weather, characterized by sunny skies, pleasant temperatures ranging from 75°F to 85°F, and remarkably low humidity. This period also avoids the Atlantic hurricane season, which runs from June to November. For those looking to experience local culture, April is also a top contender as it hosts the vibrant St. Thomas Carnival, featuring parades and food fairs. If you are looking for a balance between good weather and lower prices, the "shoulder" months of May and June are ideal; the weather remains warm and relatively dry, but the crowds from the winter cruise season have thinned out, making it easier to find a quiet spot on iconic beaches like Magens Bay. Conversely, late August and September are the months to avoid if possible, as they represent the height of storm activity in the Caribbean.
