May in St. Thomas sits at the hinge between the winter high season and the official start of Atlantic hurricane season on June 1. The cruise ships that fill Charlotte Amalie's harbor from November through April thin out, and the island settles into a quieter pace. Daytime highs reach around 27°C (81°F) with lows near 26°C (78°F), and the easterly trade winds still blow steadily enough to take the edge off the humidity. You might catch a ship or two at Havensight on a given day, but the queues at Blackbeard's Castle and the shops along Dronningens Gade shrink considerably.
This is the month when mango season begins across St. Thomas. Trees in Red Hook and Frenchtown start dropping fruit, and the sweet, resinous smell of ripe mangoes drifts from vendor tables along Route 30. Afternoon showers become a regular feature, typically arriving between 2 and 4 PM, though they rarely last more than 20 minutes before the sun returns. The rain greens up Crown Mountain and the hillsides above Charlotte Amalie in a way that the dry winter months never quite manage.
For visitors willing to trade peak-season polish for lower rates, May tends to be an underrated window. Some restaurants along the Red Hook waterfront might scale back to 5-day weeks, and a few Havensight shops close early on weekdays. But Magens Bay still opens daily, Coki Beach keeps renting snorkel gear, and the Caribbean water stays warm. The island rates 8.2 out of 10 for family friendliness (see the TTDI Family-Friendliness Index), and the lighter crowds make beaches more relaxed for families with young children.
Why visit in May
- Accommodation and activity rates drop well below the December-to-April peak, making May one of the most affordable months on St. Thomas.
- Cruise ship visits fall to 1 or 2 per week from the 4-5 per week in winter, leaving Charlotte Amalie's streets, shops, and beaches far less congested.
- Water temperatures stay warm enough for comfortable snorkeling and swimming at Coki Beach, Sapphire Beach, and the reefs along the east end.
- Mango season opens, with local varieties like Julie and common mango appearing at roadside stands and on restaurant menus in Frenchtown and Red Hook.
Worth knowing
- Afternoon rain showers arrive regularly during May, sometimes heavy enough to send everyone at the beach scrambling for cover.
- Some restaurants, tour operators, and shops reduce hours or close midweek. The Havensight area is particularly quiet on days without a cruise ship in port.
- The approach of hurricane season on June 1 can make some travelers uneasy, even though May storms are statistically very rare in the Atlantic basin.

Think twice if
May sits between St. Thomas's drier winter months and the wetter summer that follows. Highs average 27.2°C (81°F) and lows hold near 25.6°C (78°F), a narrow band that keeps the island feeling warm from dawn through evening. Humidity runs at 78%, noticeable in sheltered valleys like Tutu but tempered by trade winds along the open coasts. The month's 78mm of rain falls across roughly 12 days, almost always as short, punchy afternoon downpours rather than all-day gray. Mornings tend to start clear and calm. For context, January and March average around 33mm of rain, while August through October can bring 133 to 145mm, placing May in a comfortable middle ground. Nights stay warm enough that a thin sheet is all the bedding you need.
Seasonal caution
- UV index regularly exceeds 10 in May, high enough to cause sunburn within 15-20 minutes of unprotected midday exposure. Reef-safe sunscreen is required by USVI territorial law.
- Atlantic hurricane season officially begins June 1. May tropical storms are very rare but not impossible. Monitor NOAA forecasts for any early development, especially during the final week of the month.

Best things to do in May
Snorkeling at Coki Beach
water sportsCoki Beach on the North Side sits over a shallow reef that starts within wading distance of shore. The reef hosts parrotfish, blue tang, and sergeant majors, and the water is typically clear enough to spot them from the surface without fins.
Water visibility tends to hold higher in May than in the heavier rain months from July onward, and the winter crowds of snorkelers thin to a fraction of their peak-season numbers.Booking tipNo booking needed. Gear rental is available on the beach.
Day trip to St. John via Red Hook ferry
day tripThe ferry from Red Hook reaches Cruz Bay, St. John in about 20 minutes. From there, the North Shore Road leads to Trunk Bay, Cinnamon Bay, and the waters of the Virgin Islands Coral Reef National Monument, established in 2001.
May crowds on St. John's beaches drop sharply from winter levels, and the ferry crossing tends to be calmer than in late-summer swells.Booking tipNo advance booking for the ferry. Check the current schedule at the Red Hook terminal, since operators occasionally reduce service frequency during low season.
Walking tour of Charlotte Amalie's historic district
sightseeingThe 99 Steps, a stone-and-brick staircase from the Danish colonial period, leads up toward Blackbeard's Castle, a watchtower that predates most of the town below. Nearby, Fort Christian, the oldest standing structure in the USVI, anchors the waterfront. The Cathedral Church of All Saints, built in 1848, and the Cathedral of Saints Peter and Paul, dating to 1806, stand within a 10-minute walk of each other.
With far fewer cruise ships docking each week, the narrow streets and historic staircases become walkable at a leisurely pace for the first time in months.Booking tipSelf-guided. Pick up a map at the Visitor Center near Emancipation Garden.
Sunset at Drake's Seat
scenicDrake's Seat is a viewpoint on the North Side with views over Magens Bay and, on clear days, the British Virgin Islands across the Sir Francis Drake Channel. The bench at the top catches the breeze coming off the water.
May sunsets fall around 6:45 PM, nearly an hour later than the 5:45 PM winter sunsets, giving more post-dinner daylight for the drive up the hill.Beach hopping on the North Side
beachThe string of beaches from Magens Bay west through Hull Bay to Brewers Bay offers distinct personalities. Magens has the widest sand and calmest water. Hull Bay draws surfers when the rare north swell produces chest-high sets. Brewers Bay, near the University of the Virgin Islands campus, is a no-fee local favorite with a gradual, sandy entry.
Midweek mornings in May, you might have long stretches of sand at Brewers Bay and Hull Bay entirely to yourself. Even Magens Bay runs at a fraction of its winter capacity.Kayaking at Cas Cay mangroves
water sportsGuided kayak tours launch from the east end of St. Thomas and paddle through the mangrove channels around Cas Cay, a small island surrounded by juvenile fish, sea turtles, and wading herons. The splash of small fish and the low calls of herons are louder here than anywhere else on the island.
Reduced boat traffic in low season means calmer, quieter water in the mangrove channels. The wildlife is more visible and audible when fewer engines are running nearby.Booking tipBook morning slots at least 2-3 days ahead. Most operators run only one or two departures per day in May.
Exploring Frenchtown
neighborhoodFrenchtown, a former French Huguenot fishing settlement west of Charlotte Amalie, keeps a low-key waterfront with restaurants, a small harbor where fishermen unload the day's catch in the salt-air afternoon light, and St. Anne Chapel, which dates to 1921.
The neighborhood's restaurants have open tables for walk-ins throughout May, and the fishing boats returning in the late afternoon make for unhurried waterfront evenings without tour-group competition.What to eat in May
In season: fruit
Mango
Mango season opens across St. Thomas in May. Local varieties like Julie and common mango appear at roadside stands and on menus island-wide. The Julie is smaller and more aromatic than the supermarket Tommy Atkins most visitors know from the mainland.
Soursop
The spiky green soursop reaches peak ripeness in the Virgin Islands in late spring. Its tart, custardy flesh shows up in fresh juices and smoothies at shops along the Charlotte Amalie waterfront.
On menus now
Callaloo
This thick, stew-like dish of leafy greens, okra, and often local fish or crab reaches its best form when May's early rains coax fresh dasheen leaves into abundance at hillside farms above Frenchtown.
Street food peaks
Conch fritters
Fresh, locally caught queen conch becomes harder to find as summer approaches, making May one of the last months when the golden, crispy fritters are likely made with conch from local waters rather than imported.
What to drink
Passionfruit punch
Passionfruit ripens across the Virgin Islands starting in May. The tart, floral juice is mixed with local rum or served straight over ice at rum bars on Back Street in Charlotte Amalie.
Regular events in May
Memorial DayFree
Federal public holiday observed across the U.S. Virgin Islands. Charlotte Amalie hosts a ceremony at the Veterans Drive memorial, and beaches across the island draw families and gatherings for the long weekend.
Last Monday of MayMother's DayFree
Observed on the second Sunday of May. Restaurants across St. Thomas run special brunch services, and Magens Bay and the North Side beaches see higher-than-usual family turnout for the weekend.
Second Sunday of MaySt. Thomas Carnival Village closing nights
The tail end of the USVI's largest annual celebration, with the main parades typically held in late April. In years when the schedule extends, the Carnival Village on the Charlotte Amalie waterfront keeps its food stalls and music stages open into the first days of May.
Early May (varies annually, check USVI Carnival schedule)Best places this May
Magens Bay Beach
beachThe wide, horseshoe-shaped beach on the North Side is St. Thomas's most recognized stretch of sand, sheltered enough that the water stays calm even when trade winds pick up offshore.
North SideBlackbeard's Castle
historic landmarkThis National Historic Landmark sits above the 99 Steps in Charlotte Amalie. The stone watchtower and surrounding gardens offer one of the best elevated views of the harbor and the town's red rooftops below.
Charlotte AmalieFort Christian
historic landmarkThe oldest standing structure in the USVI, this Danish-era fort on the Charlotte Amalie waterfront houses a small museum with artifacts from the colonial and pre-colonial periods. The thick coral-stone walls stay noticeably cool inside.
Charlotte AmalieSapphire Beach
beachAn east-end beach with good reef snorkeling directly offshore. The rocky points on either side of the sand concentrate fish and make for easy snorkel loops without needing a boat.
East EndBrewers Bay
beachA free-access beach near the University of the Virgin Islands campus on the west side. Quieter than the better-known beaches, with a gradual sandy entry and afternoon shade from the surrounding hillside.
West SideEmancipation Garden
parkA small public park in the center of Charlotte Amalie, surrounded by historic buildings including the Legislature of the Virgin Islands. The park commemorates the emancipation of enslaved people in the Danish West Indies in 1848.

Insider tips
The safari buses, open-air trucks with bench seating and the warm wind in your face, run set routes between Charlotte Amalie and Red Hook for a fraction of what a private taxi charges. You can flag one down anywhere along its route. Look for the open-back trucks with wooden or metal bench seats.
Brewers Bay, near the University of the Virgin Islands campus, has free parking and no entrance fee. On weekday mornings in May, you might be one of 5 or 6 people on the entire beach.
The shops on Dronningens Gade (Main Street) are duty-free. Mind you, with fewer cruise ship visitors in May, the pace is slower and shopkeepers tend to be more available for conversation than during the heavy-traffic days of winter.
If you rent a car, note that the USVI drives on the left side of the road using left-hand-drive American vehicles. The combination feels strange at first, especially on the steep, narrow roads around Crown Mountain. Gas stations near Tutu and the Red Hook roundabout are the most convenient for refueling.
Avoid these mistakes
- Packing only for sun. The afternoon rain pattern in May catches plenty of visitors off-guard, and the downpours are heavy enough to soak everything in an open bag within minutes. Keep a rain layer and a dry bag in your day pack.
- Booking all outdoor excursions for the afternoon. Morning hours before 11 AM are the most reliable window for clear skies and calm water in May. Most tour operators offer both morning and afternoon slots, and the morning departure fills first among experienced visitors for good reason.
- Buying international phone plans, travel adapters, or converting currency before traveling to St. Thomas. The USVI is a U.S. territory. American cell service, electrical plugs, and the dollar all work exactly as they do on the mainland, so none of these purchases are necessary.
Practical tips for May
Book rental cars at least a week ahead, even in low season. St. Thomas has limited rental inventory and the agencies near Cyril E. King Airport can run short over Memorial Day weekend. Check the Red Hook ferry schedule before heading to the east end, since operators sometimes adjust frequency during May. Most restaurants in Charlotte Amalie and Frenchtown accept walk-ins during this quieter month, though the popular spots along the Red Hook waterfront fill up on Friday and Saturday evenings and benefit from a reservation. Tap water comes from the island's desalination plants and rain catchment cisterns, safe to drink but with a mineral edge that sends most visitors to the filtered-water refill stations at grocery stores in Tutu.
FAQ
Is May a good time to visit St. Thomas?
May is a solid shoulder-season option for St. Thomas. Hotel and rental rates drop well below the winter peak, cruise ship traffic falls off, and the weather remains warm and mostly sunny. To be fair, afternoon showers are more frequent than in the driest winter months, but they pass quickly and rarely ruin a full day. The combination of lower rates and thinner crowds makes it a genuinely appealing time to visit.
What is the weather like in St. Thomas in May?
Warm and humid, with daytime temperatures in the upper 20s Celsius (low 80s Fahrenheit) and little variation between day and night. Rain increases compared to winter but usually arrives in brief afternoon bursts rather than daylong downpours. Trade winds along the coasts keep the air moving, and most mornings start clear and sunny with calm seas.
Is St. Thomas crowded in May?
Not at all. May is one of the quieter months on St. Thomas. The cruise ships that bring thousands of day-trippers during the November-to-April high season largely stop calling. Hotels and beaches operate well below capacity. You can expect shorter waits at popular spots like the 99 Steps and Magens Bay, and walk-in tables at most restaurants.
Is it hurricane season in St. Thomas in May?
Officially, no. The Atlantic hurricane season opens at the start of June and runs through the end of November. May sits before that window. Tropical storms in May are statistically rare in the Caribbean, and the probability of one affecting St. Thomas specifically is very low. That said, monitoring NOAA forecasts during the final week of the month is a reasonable precaution.
Is St. Thomas safe for solo travelers?
St. Thomas scores 6.2 out of 10 for solo-traveler safety (see the TTDI Solo-Safety Index). The main tourist areas, including the Charlotte Amalie historic district, Red Hook, and the major beaches, are generally safe during daylight hours. Standard precautions apply after dark. Avoid walking alone at night on unlit roads, use taxis or safari buses for nighttime transport, and keep valuables secured at your accommodation.
