When to go
Best time to visit United States Virgin Islands
USVI water is warm year-round, but weather and exposure matter more than calendar averages.
Best overall window
December - April
Relatively drier conditions with strong winter trade winds and occasional north swell; St. Croix and St. John can differ by exposure.
Outside that window
Hotter, wetter conditions and elevated tropical-storm interruption risk, especially late summer and early autumn.
