St Barts In August

August sits inside the island's low season and inside hurricane season. Here is what the climate normals, the closure calendar and the transport options actually say about St Barts in August.

August on St Barts is warm, quiet and low season. Meteo-France normals show a mean daily high of 31.6 C, the island falls inside the Atlantic hurricane season, which runs 1 June to 30 November, and many hotels close from late August until they reopen between mid-October and early November.

St Barthelemy, usually written St Barts, is a small French island in the Caribbean, and August is its quietest stretch of the year outside September. The harbour town of Gustavia slows down, several of the big hotels shut their doors for their annual break, and the sea is at its warmest. It is also the heart of the Atlantic hurricane season, which changes how you plan. This guide sets out what the climate normals, the closure pattern and the transport picture actually say, month by month, so an August trip can be judged on facts rather than on a brochure's idea of the island.

Is August A Good Time To Visit St Barts?

August suits travellers who want warm water, empty beaches and lower demand, and who accept the hurricane-season trade-off. The Meteo-France normals, 1991-2020, put the mean daily high at 31.6 C with a mean daily low of 26.3 C, and the sea is warm at about 29 C from August to October. Many hotels close from late August, so accommodation is a villa or one of the year-round properties.

The honest framing is that August is a low-season month with two distinct faces. One face is physical: the island is warm, the water is at its warmest of the year, and the crowds of the December to April high season are absent. The other face is structural: the Atlantic hurricane season runs from 1 June to 30 November with its peak from mid-August to mid-October, and the island's hotel and restaurant calendar responds by closing many properties for their annual break.

That closure pattern matters as much as the weather. Many hotels and restaurants close each autumn and reopen in waves between mid-October and early November, and the closures typically begin in August. Anyone booking an August stay should confirm directly with a property that it is open, or plan around a villa rental, since villas generally stay available year-round.

For a wider view of the seasons, the St Barts season guide context covers what the accommodation landscape looks like across the year, and the site's root page on things to do in St Barts lists the activities that exist at all.

What Is The Weather Like In St Barts In August?

The Meteo-France normals, 1991-2020, for the St Barthelemy station show August with a mean daily high of 31.6 C, a mean daily low of 26.3 C and 79.6 mm of rain across the month. The sea around the island is warm, about 29 C from August to October according to a secondary source. August is warm and humid but not the wettest month; October holds that title at 135.6 mm.

Those normals deserve a careful read, because they cut against two common assumptions. First, August is not the wettest month on the island: October is, at 135.6 mm, and November follows at 118.6 mm. August, at 79.6 mm, sits mid-table, wetter than the February low of 38.4 mm but well below the autumn peak. Second, August is not the warmest month either in terms of mean daily high: September edges it, 31.7 C against 31.6 C, a difference with no practical meaning for a traveller.

Month Mean daily high Mean daily low Rainfall
June 31.2 C 25.9 C 56.0 mm
July 31.2 C 26.0 C 80.4 mm
August 31.6 C 26.3 C 79.6 mm
September 31.7 C 26.2 C 96.9 mm
October 31.4 C 25.8 C 135.6 mm

Rain in the tropics also behaves differently from rain in northern Europe. The normals give a monthly total, not a pattern, and how that rain arrives in August, whether as brief showers or longer spells, remains unclear. What can be said is that the island is warm year-round, that trade winds are a general feature of the Caribbean climate, and that no prediction of rain, storms or crowds for a specific date is possible or honest.

For travellers already planning around the warm water, the boat trips that visit St Barts from St Martin keep running through the summer, and the one per-person group sail listed here runs from 12 May to 31 August 2027 on its listing.

What About Hurricanes In St Barts In August?

The Atlantic hurricane season runs from 1 June to 30 November, with activity typically peaking from mid-August to mid-October and a climatological peak near 10 September. Hurricane Irma struck the island in September 2017. August sits inside the season, so travel insurance and flexible bookings matter.

The island's most significant recent weather event was Hurricane Irma in September 2017, which caused widespread destruction across St Barts and the neighbouring islands. The island rebuilt, and the properties standing today are largely post-Irma rebuilds, but the event explains why the season is taken seriously in local planning, why the autumn closure window exists and why the biggest hotels schedule their maintenance for these months.

What August travellers should actually do is procedural rather than fearful. Check the National Hurricane Center's Atlantic outlook in the days before travel, as conditions are monitored continuously through the season. Book refundable rates where possible. Carry the island's emergency numbers, which follow the standard French system: 15 for medical emergencies, 17 for police, 18 for fire and 112 as the general European emergency number. And know that ferry services between St Martin and St Barts are subject to weather cancellations, since the crossing can be rough.

For a summer or autumn boat day booked from St Martin, flexibility is built into the products: the operator's live listing shows the cancellation terms before payment, and pay-later options are common.

What Is Open On St Barts In August?

Many hotels and high-end restaurants close for their annual break in late August and reopen in waves between mid-October and early November, a repeating pattern rather than a fixed calendar. Villas generally remain available year-round, a small number of hotels and local restaurants stay open, and all public beaches remain open and free to access throughout the year.

The closure wave is the single biggest practical fact about August on the island. The large properties, including the well-known luxury hotels on Flamands, Grand Cul-de-Sac and Pointe Milou, shut in late August for maintenance and staff holidays, and their restaurants and beach clubs close with them. The reopening happens in stages from mid-October, with a few properties holding out until early November.

Large luxury hotels Many closed from late August, reopening mid-October to early November
Hotel restaurants and beach clubs Generally follow the hotel's closure
Independent local restaurants A smaller number stay open year-round
Villas Generally available year-round
Public beaches Open and free, all year
Car rental counters at SBH Operating year-round

The practical reading: an August visitor who wants a hotel should verify with the property directly before booking anything non-refundable, and an August visitor who wants space and independence is naturally pushed toward the villa market, where a large villa market exists with no reliable count and managers including WIMCO, Sibarth and St Barth Properties operate on the island. More on the accommodation landscape is in the site's guide to St Barts hotels and its overview of luxury hotels in St Barts.

Restaurants that stay open skew local and casual, and no restaurant on the island is named here as a recommendation. The food scene in general terms is French-influenced, in keeping with the island's status as an overseas collectivity of France since 2007.

One event fills the late-August lull locally: the island's patron-saint feast, the Fete de Saint-Barthelemy, falls in late August with ceremonies and fireworks in Gustavia, per the tourism committee's calendar. It is a local occasion rather than a visitor-facing festival, and details vary year to year. By contrast, the next dated island event is the St Barth Gourmet Festival, which runs 9 to 15 November 2026, after the reopening wave.

How Do You Get To St Barts In August?

There is no direct long-haul service: the airport's 646 m runway accepts only small STOL turboprops in daylight and visual conditions, so the standard route is a gateway flight to St Martin, then a short hop by small plane or a ferry crossing of about 45 minutes from Philipsburg or about 50 to 60 minutes from Marigot. Two ferry operators run the route, and sailings are weather-dependent.

The gateway logic is fixed by physics. Gustaf III Airport, also called Remy de Haenen, has a single 646 m runway, no jets land there, and operations are daylight and visual-only. Travellers fly into St Martin, either Princess Juliana on the Dutch side or Grand Case on the French side, then connect. St Barth Commuter flies from SXM, Grand Case and Guadeloupe, Tradewind flies from San Juan and Antigua, and Winair serves the island from St Martin. Each hop is a short flight.

Route to St Barts Operator Mode
From St Maarten airport (SXM) St Barth Commuter, Winair Small plane, short hop
From Grand Case, St Martin (SFG) St Barth Commuter Small plane, short hop
From Guadeloupe (PTP) St Barth Commuter Small plane
From San Juan (SJU) and Antigua (ANU) Tradewind Small plane
From Philipsburg, Sint Maarten Great Bay Express Ferry, about 45 minutes
From Marigot, St Martin Voyager Ferry, about 50 to 60 minutes

The two ferry operators are the budget-conscious alternative. Great Bay Express departs from Bobby's Marina in Philipsburg on the Dutch side, and Voyager departs from the Marigot ferry terminal on the French side; both run roughly two to three sailings a day in each direction, more in the high season, and both require a passport. Neither operator's fare is listed. The crossing can be rough, and August swell is a real possibility, so anyone prone to seasickness should weigh the plane connection instead. Full detail is in the site's guides to how to get to St Barts and the St Barts ferry operators and schedule.

August also trims the flight schedule slightly, since frequencies rise and fall with the November to April high season. The site's St Barts airport guide covers the arrival experience, including the well-known landing approach, and flights to St Barts covers routing from the US.

Things To Do In St Barts In August

The core August activities are the ones the island offers year-round: the public beaches, all free and open, the water, and the surrounding marine reserve, which lists 23 dive sites, a 5-knot speed limit in its zones, a ban on jet skis and a rule against touching turtles or bringing dogs onto beaches. No on-island activity is bookable through this site; every bookable tour departs from St Martin or Sint Maarten and visits St Barts by sea.

The beach list is the island's backbone. Saint-Jean, Gouverneur, Saline, Shell Beach, Flamands, Colombier, Grand Cul-de-Sac, Lorient, Toiny, Marigot, Corossol and Anse des Cayes are all public and free, and in August they are at their emptiest. Say nothing more specific about any beach than that, and leave location and access to each beach's own guide page on this site.

The marine reserve rules come from the environment agency's regulatory-zones page and shape any day on or under the water. The reserve covers zones including Colombier Bay and Ile Fourchue, and its rules are listed in the table below.

Marine reserve rule Source
5-knot speed limit in protected zones Environment agency regulatory-zones page
No jet skis, seabobs or towed sports Environment agency regulatory-zones page
No touching or chasing turtles, corals or protected species Environment agency regulatory-zones page
No dogs on beaches or in the water in reserve areas Environment agency page

For a structured day on the water, the one per-person product is the Gustavia, Colombier and Ile Fourchue group sail, which departs from St Martin, spends a full day around St Barts and runs from 12 May to 31 August 2027 on its listing, which makes August the final month of its season. Beyond that product, the bookable options are private charters from St Martin, none of which departs from St Barts itself.

On land, the free options are exactly the beaches and open public places, and no walking tour is listed here. Gustavia's harbour, the forts Karl and Gustaf, and the small museums fill a slow day, each with its own page on this site. A rental car is the usual way to reach them: driving is on the right, roads are narrow and steep, and the island-wide limit is 50 km/h with 30 km/h in Gustavia and Saint-Jean. More detail is in the guide to St Barts car rental.

Where To Stay In St Barts In August?

An August stay is realistically a villa, a year-round smaller property or a hotel that has confirmed it is open, since the large hotels close from late August until reopening between mid-October and early November. Rates, where published at all, vary by season, and the property's own booking page is the source of truth for price.

The villa route has practical advantages in August beyond availability. Villas come with their own kitchen, which matters when a share of the island's restaurants is closed, and they suit the slower rhythm of a low-season week. The villa market on St Barts is large, managed by firms including WIMCO, Sibarth and St Barth Properties, and bookings are typically made direct or through a specialist rather than through a general platform.

The hotel route in August needs verification first and booking second. Each property sets its own closure dates, and the pattern shifts year to year, so the sequence is: shortlist from the site's guides to beach hotels in St Barts or boutique hotels in St Barts, confirm the property is open for the dates, then book refundable where possible given the hurricane-season overlap.

Should You Book A Boat Day From St Martin In August?

Yes, if the summer calendar fits: August is the last month of the per-person group sail's season, which runs 12 May to 31 August 2027 on its listing, and the private charter options from St Martin and Sint Maarten run year-round. All of them depart from the St Martin side, visit St Barts by sea, and are subject to weather, so a flexible or refundable rate is the sensible August choice.

The choice between them is about party size and style, and the trio below spans it: a per-person group sail with snorkelling stops, a full-day private charter for up to eight, and a two-day one-night private catamaran that turns the crossing into the trip itself. Prices, ratings and durations render in the cards from live listing data rather than being typed here, since product figures come only from the operators' listings.

The marine reserve rules from earlier apply to all of them, particularly the 5-knot limit and the no-touch rules for turtles, which are common in the waters around Colombier and Grand Cul-de-Sac. In August the sea is warm, about 29 C, which makes the snorkelling stops part of the appeal.

Is August Cheaper Than Winter On St Barts?

No fare, nightly rate or price comparison prices the difference. What the calendar shows is structural: August is low season, the big hotels are closed or closing, the event calendar is empty until the Gourmet Festival on 9 to 15 November 2026, and the island refills for the December to April high season, which peaks around New Year's Eve in Gustavia.

Low season shows up in availability rather than in printed numbers. The quietest stretch runs from late August through September and early October, with the reopening wave from mid-October and the first major event of the new season, the St Barth Music Festival, running 8 to 18 January 2027. Anyone comparing August against the winter peak can read the shape of the year in the table below; the actual prices belong to each operator's and property's own booking page.

Period Island calendar pattern
Late August Major hotels closing for the annual break, patron-saint feast in Gustavia
September to early October Deepest low season, quietest stretch of the year
Mid-October to early November Hotels and restaurants reopen in waves
9 to 15 November 2026 St Barth Gourmet Festival
December to April High season, peak around New Year's Eve

For contrast, the site's guide to New Year's Eve in St Barts shows what the other end of the calendar looks like, when Gustavia's harbour fills with superyachts and the island is at full capacity.
