What September is like in St. Lucia
September is the height of both hurricane season and the rainy season. Highs sit near 88F (31C), the air is very humid, and big storms can trigger landslides that close mountain roads. Some smaller hotels and restaurants close for maintenance. Crowds and prices are at their lowest.
We would steer most travelers away from September. The storm risk is highest, and rain can wash out hikes and road trips. If low prices matter most, buy insurance, book refundable rooms, and stay flexible. For the best weather, plan for January through May.

What's on in September
Gros Islet Friday Night Street Party
Every Friday night, year-round
A weekly party in Gros Islet with food stalls and music. The easiest way to experience local nightlife.
Things to do in St. Lucia
Gros Piton hike
A steep, guided climb of a few hours round trip. Start early in the dry season; the trail is slick and hot later in the day.
Tet Paul Nature Trail
A short, easy trail near Soufriere with one of the best views of the Pitons. Great for non-hikers.
Diamond Falls Botanical Gardens
Gardens and a mineral-tinted waterfall near Soufriere, with historic mineral baths.
Sulphur Springs
The volcanic vents and mud baths near Soufriere. Go early before tour groups arrive.
Pigeon Island National Landmark
Fort ruins and hilltop views at the north end, connected to the mainland near Rodney Bay.
Marigot Bay
A sheltered bay surrounded by hills, known for yachts and sunset drinks. Calm and beautiful year-round.
Beat the crowds
- Visit Sulphur Springs, Diamond Falls, and Tet Paul at opening time, before the cruise and day-trip groups arrive from the north.
- Base in Soufriere, near the Pitons, instead of Rodney Bay if you want nature and quiet. The drive between the two takes over an hour on winding roads.
- Travel in May and early June for dry-season weather at shoulder prices.
- Check the Castries cruise schedule: popular sights and beaches are busier on ship days.
Know before you go
- September and October: some smaller hotels and restaurants close for maintenance. The major resorts mostly stay open.
- After heavy rain, the west coast road between Castries and Soufriere can be closed by landslides. Allow extra time in the rainy season.
- The Gros Piton trail and rainforest trails can be muddy and slippery from June to November; guides may cancel after heavy rain.
- Public holidays such as Independence Day, Emancipation Day (August 1), and Carnival Monday and Tuesday close government offices and some shops.
