Virgin Islands Weather: Forecasts, Climate, and Current Conditions
Virgin Islands has a stable tropical maritime climate, tempered year-round by trade winds blowing east to west across the Atlantic. Warm all year (between 77 and 90°F) and never freezing, the park has two distinct seasons: a dry season from December through April, with steady winds and little rain, and a wet season from June through November, marked by afternoon thunderstorms and hurricane monitoring. The good news is that even in the middle of August, a tropical shower rarely lasts more than 30 minutes.

Virgin Islands Climate Month by Month
The averages below are for the island of St. John. Temperatures vary little from year to year. Rainfall is what really marks the boundary between the seasons.
| Month | Low (°F) | High (°F) | Rainfall (in.) | What to expect |
|---|---|---|---|---|
| January | 73 | 82 | 2.6 | Dry, strong trade winds, rough seas to the north |
| February | 73 | 82 | 2.2 | Driest month of the year |
| March | 73 | 84 | 2.2 | Dry, gradually warming |
| April | 75 | 86 | 2.6 | Transition month, first occasional showers |
| May | 77 | 88 | 3.1 | Trade winds weaken, humidity rises |
| June | 79 | 88 | 3.5 | Official start of hurricane season |
| July | 79 | 90 | 4.3 | Afternoon thunderstorms almost daily |
| August | 81 | 90 | 4.7 | Peak heat and hurricane risk |
| September | 81 | 90 | 5.5 | Wettest month, highest level of caution |
| October | 79 | 88 | 5.3 | Still wet, often rough seas |
| November | 77 | 86 | 4.3 | Trade winds gradually return |
| December | 75 | 84 | 3.1 | Dry season settles in |
Water temperatures range from 81 to 84°F depending on the season, making conditions ideal for snorkeling and scuba diving year-round.
Climate Season by Season
Winter (December to February): The Dry Season in Full Swing
Trade winds blow at their strongest, averaging around 12 to 19 mph. As a result, days around 82°F can feel almost cool in the wind. Rain is rare and skies are clear. North-facing beaches such as Cinnamon Bay and Francis Bay can have rough seas that are not ideal for swimming. Sheltered coves to the south, including Salt Pond Bay, stay calm. This is peak tourist season, so accommodations and ferries fill up weeks in advance.
Spring (March to May): The Overlooked Window
Trade winds gradually weaken starting in April, temperatures climb toward 86 to 88°F, and the first brief showers return in May. Seas on the north side calm down, creating ideal conditions for kayaking and diving. Crowds thin out after the American spring breaks in March, and the Reef Bay Trail and Bordeaux Mountain Trail are nearly empty. This is probably the best balance of comfort and peace and quiet all year.
Summer (June to August): Hot, Humid, and Stormy Late in the Day
Temperatures reach 90°F, with high humidity. Afternoon thunderstorms are almost guaranteed from July through August. Plan your hikes in the morning, before 10 a.m., to avoid the combination of heat and humidity on exposed trails. Underwater visibility is excellent between rainy spells, and the water reaches its warmest point at 84°F. Hurricane season begins June 1, so check weather bulletins every morning.
Fall (September to November): Peak Hurricane Season, Then a Slowdown
September is statistically the most active month for hurricanes in the eastern Caribbean. Planning a trip without solid trip-cancellation insurance would be unwise. October remains wet, but the risk decreases. In November, the trade winds return and rainfall drops noticeably. The last few weeks often feel like peak season, but with far fewer visitors.
Does It Get Cold in Virgin Islands? Records and Extremes
No, it never really gets cold on St. John. The coldest January nights rarely dip below 68°F. Bring a light jacket for ferry rides or overly air-conditioned restaurants, not to protect yourself from the outdoor cold. At the other extreme, August and September days can top 91°F with high humidity. Heat exhaustion is still possible if you string together hikes in full sun without drinking regularly.
It never snows in the U.S. Virgin Islands. The confusion sometimes comes from a name mix-up: Virginia is a mainland U.S. state with pronounced winters, while Virgin Islands National Park lies on the tropical island of St. John in the Caribbean.
What to Wear by Season
The basics stay the same year-round: lightweight, breathable clothing (linen, technical cotton, or quick-drying synthetics), at least SPF 50 sunscreen, and a wide-brimmed hat. UV levels are high in the tropics, even under cloudy skies.
Dry season (December to April): Pack a light windbreaker for ferry crossings and ridge hikes exposed to the trade winds. Evenings can feel cool after a day on the water, so a light layer is worth bringing.
Wet season (June to November): A compact rain jacket or poncho is enough for tropical showers. Waterproof hiking shoes are useful on trails that are soaked after rain. Bring water shoes or sandals with good traction for rocky approaches to the beaches.
Alerts and Conditions to Watch
Hurricane season (June 1 to November 30): Check National Hurricane Center bulletins and alerts posted on the NPS website every day. A hurricane can suspend ferries between St. Thomas and St. John with very little notice, and there may be no alternative.
Winter swell: From December through March, swells generated by offshore storms can make north- and east-facing beaches dangerous for swimming, with waves reaching 5 to 7 feet at Hawksnest Bay and Francis Bay. Sheltered coves to the south remain usable.
Trails after heavy rain: Some trails close temporarily after intense rainfall. Check conditions before every outing with rangers or at nps.gov/viis.
Boating and water activities: Boaters and kayakers should check wind and swell forecasts. St. John's north coast can be rough all winter, while the south coast is generally protected.
Frequently Asked Questions
Does it ever get cold in the U.S. Virgin Islands?
It rarely gets cold in the U.S. Virgin Islands. Nighttime temperatures seldom fall below 68°F, even in January, the coolest month. A light jacket is enough for ferries and windy evenings.
Does it snow in Virgin Islands?
It never snows in Virgin Islands. The national park lies on the tropical island of St. John in the Caribbean, where temperatures never drop low enough for snow. Do not confuse it with Virginia, a mainland state that experiences real winters.
What is the best month to visit the U.S. Virgin Islands?
The best month depends on your priorities: December through February for the driest, most reliable weather; March through April to avoid peak season while keeping pleasant conditions; or November for almost-summer weather without the crowds. Our When to Visit Virgin Islands page compares every season in detail.
Which U.S. Virgin Islands island is safest to visit?
St. John, home to the national park, is known for its peaceful character. Two-thirds of the island is protected by the National Park Service, which sharply limits development and crowds. Safety concerns are more relevant in the urban areas of St. Thomas and St. Croix, outside the park boundaries.
