| Month | Avg °F | Sun | Rain | Season | What it's like |
|---|---|---|---|---|---|
| January | 70–82°F | 8h | Moderate (68mm) | Peak | Peak dry-season sun settles in over St. Thomas and St. John—crisp mornings, warm turquoise water and the year's calmest seas. |
| February | 70–82°F | 8h | Moderate (54mm) | Peak | Bone-dry and breezy with the season's best snorkeling visibility; hotel rates stay at their winter high. |
| March | 70–82°F | 9h | Moderate (57mm) | Peak | Still firmly in dry season—clear skies over Magens Bay and Trunk Bay with light, comfortable humidity. |
| April | 72–84°F | 9h | Moderate (88mm) | Peak | Warm and mostly dry as winter crowds thin slightly; a great shoulder-of-peak window for value without sacrificing weather. |
| May | 73–84°F | 8h | High (129mm) | Shoulder | Humidity starts to build and afternoon showers become more frequent, but mornings are still reliably sunny. |
| June | 75–86°F | 8h | Moderate (73mm) | Shoulder | Hot, increasingly humid, and the start of hurricane season—short tropical showers roll through most afternoons. |
| July | 75–86°F | 9h | Moderate (85mm) | Shoulder | Consistently hot with brief, heavy downpours; underwater visibility stays excellent between showers. |
| August | 75–88°F | 9h | High (124mm) | Off-Peak | The wettest stretch of summer arrives with high heat and the occasional tropical system to track. |
| September | 75–88°F | 8h | High (143mm) | Off-Peak | Peak hurricane season—the quietest, cheapest month to visit, with dramatic afternoon storms and thinned-out beaches. |
| October | 75–86°F | 8h | High (161mm) | Off-Peak | Still deep in hurricane season with the year's heaviest rainfall, though many days open with clear skies before storms build. |
| November | 73–84°F | 7h | High (161mm) | Shoulder | Rain begins to ease as the dry season approaches, with warm, humid air and improving conditions late in the month. |
| December | 72–82°F | 7h | High (119mm) | Peak | Dry season returns in style—sunny, breezy days and the build-up to the islands' festive Crucian Christmas season. |
