US Virgin Islands weather by month

US Virgin Islands weather hardly moves in temperature; rain and storms decide the trip. For the driest sky, the best time to visit the US Virgin Islands is February and March, at the high-season rate. For the price, May and June: the low rate, and no storm on either island's record. Below, how St. John and St. Thomas differ.

How the weather works across the territory

One number decides the year here, and it is not the temperature. The afternoon high at Cyril E. King airport, the station with temperature normals on St. Thomas or St. John, moves six degrees across the year on NOAA's 1991 to 2020 record, 84 in January and 90 in July. Rain moves threefold, 1.9 inches in February and 6.1 in November. Storms cluster harder still: August, September and October account for 16 of the 19 systems our count puts within 100 km of St. John from 1991 to 2024.

St. Croix has its own airport station and its own record, and this page leaves it out; the villas listed here are on St. John and St. Thomas.

The price runs on a simpler calendar. On the villas listed here, the low season runs from mid-April to mid-December at one rate as of October 2026, and the winter months above it are the dear ones. So the dry weather costs most, and from mid-April a week in May costs what a week in September does.

St. John or St. Thomas: one sky, two records

The two islands share a thermometer. St. John has no temperature station, so both weather pages print the airport's highs and lows, and the sea off Cruz Bay and off Charlotte Amalie reads within a degree in every month. Which island is warmer is a question the record cannot answer.

Rain is where they differ, and the gauges say by how much. The Coral Bay gauge on St. John's east end records 45.9 inches a year on the same normals, the East End gauge on St. Thomas 40.9, and the airport between them 41.5. The gap opens late in the year: 7.2 inches at Coral Bay in November against 6.1 on the East End, 6.3 against 4.9 in October. In March the East End reads 1.3 inches, the driest number either island has.

The storm counts differ too, by less than they look. St. John's circle holds 19 systems and 10 hurricanes in 34 seasons, St. Thomas's 17 and 7. The three hurricanes in one circle and not the other, Lenny in 1999, Omar in 2008 and Earl in 2010, all passed more than 90 km from Cruz Bay, at the edge of a circle drawn from Cruz Bay rather than Charlotte Amalie. The difference is where we put the compass. Marilyn, Georges, Irma, Maria and Dorian are on both lists.

The dry season, the shoulder and the storm months

December to April is the dry season and the high season at once. February and March are the floor of the rain column at 1.9 inches, on five wet days or fewer, and no tropical system has come within 100 km of either island in those months in 34 seasons.

Late April to July is the shoulder. The villas listed here move to the low rate in mid-April, as of October 2026; the airport reads 87 in May and 89 in June, with 3.0 and 2.4 inches of rain; and across the four months the storm record on both islands holds a single hurricane, Bertha in July 1996.

August to October is where the risk lives: 16 of St. John's 19 systems and 15 of St. Thomas's 17, at the same low rate as May, with the National Hurricane Center's peak on September 10. November is the wettest month at the airport, 6.1 inches on ten wet days, with one late hurricane on St. John's record and none on St. Thomas's.

What the rain is like on both islands

A wet day on NOAA's count is a tenth of an inch or more, and the airport records 82 of them a year, which leaves 283 dry ones. What the wet season adds is a shower on a few more afternoons and a heavier one when it comes; a day lost from breakfast to dinner is what a tropical system brings, not what November brings.

Where the house sits moves the number as much as the month does. Coral Bay's gauge reads an inch or more above the airport's from October to December, and the East End of St. Thomas is drier than the airport in February and March.

When to go: dry sky, low rate or empty beaches

For the surest sky, February or March on either island, booked months ahead at the high-season rate. For the low rate without the storm record, May and June, and accept 87 to 89 degree afternoons for it. For the emptiest beaches, September, at the same rate as May and with the season's real risk attached: insurance bought at the deposit and dates that can move.

For the drier island from September to December, St. Thomas's East End over St. John's; in the dry months the gauges agree and the choice is the ferry, not the weather. If the dates cannot move, book outside August to October.
