St. Thomas weather in March is sunny, warm and mildly breezy, usually an ideal combination for a perfect vacation.

St. Thomas is a major hotel and especially a major cruise destination in the U.S. Virgin Islands. It is known for its widespread entertainment, duty free shopping and beautiful beaches.

March falls in the middle of the island’s dry season, which runs from December to May. During this time, there is little rain and no chance of hurricanes. March is one of the best times to visit the island.

The only downside to visiting St. Thomas during this season is a major increase in tourists. March tourism in the Caribbean is often higher than normal because of children and college students on spring break.

Average Rainfall in March

It rains very little during the month. St. Thomas receives on average 1.5 inches of rainfall during March, according to the U.S. National Weather Service.

Most of this rainfall comes in the form of light sporadic showers that pass quickly, lasting only minutes and sometimes seconds.

Because of the rain, the island sometimes has a high amount of cloud cover. The clouds move quickly, and a day that is overcast in the morning will often be clear by midday.

On average, the Virgin Islands receive 40 inches of rainfall per year. Most of this rainfall occurs during the wet season, also known as hurricane season, which runs from June to November.

During these months, the average monthly rainfall rises to more than five inches. So March looks good by comparison.
