Where to Go in Mauritius in September
North & Northwest Coast
Grand Baie, Trou aux Biches, Cap Malheureux
September brings steadily rising temperatures without a return to heavy rains; the north warms early in the day and evenings remain pleasant with the trade winds easing slightly. This is a good month for water sports - windsurfing and sailing schools in Grand Baie are active - and gardens are flowering after the winter dry spell. Expect moderate crowds as international flights ramp up; book transfers to foreign-island excursions in advance.
West Coast & Coral Reef Lagoons
Flic en Flac, Tamarin, Le Morne
September sees a gentle warming and diminishing winds; more sun and higher sea temperatures return, making the shallows by Flic en Flac ideal for families. Beach bars and restaurants enjoy steady business, and inland excursions to Chamarel’s viewpoints are pleasant without heavy rain. Bring reef-safe sunscreen and plan for more beach time as the west coast edges into its busier spring season.
East Coast & Windward Beaches
Belle Mare, Palmar, Île aux Cerfs
September’s easing winds bring warmer days and calmer afternoons; the east coast sees increasing sunshine and more predictable sea conditions for swimming at protected breaks. Boat trips to Île aux Cerfs resume fuller schedules and the coastal paths are pleasant for morning runs with fewer flies and less humidity. Expect a gradual return of international visitors and book transfers early for weekend stays.
South & South-West Coast
Le Morne, Gris Gris, Souillac
September sees gentler winds and a gradual warming that makes coastal walks and swimming in protected enclaves more tempting; long beach runs around Le Morne are pleasant at sunrise. This month tends to be quieter than the peak holiday season, giving a good window for exploring Souillac and its coastal attractions without crowds. Bring reef-safe sunscreen and expect more predictable sea conditions for boat outings.
Central Plateau & Mountains
Curepipe, Moka, Black River Gorges
September’s warming days bring the plateau out of its winter calm: wildflowers appear and the undergrowth brightens while nights remain cool. This is a fine month for multi-day treks that cross different elevations and habitats without the hazards of wet-season mud. Carry water and a light jacket for evenings and expect easier travel logistics to highland destinations than on the coasts.
Rodrigues Island
Port Mathurin and outer reefs
September warms gradually and the lagoon becomes more inviting for swimmers and snorkellers; visibility for reef dives improves as runoff remains low. This month is well-suited for exploratory trips to lesser-known coves and natural pools in the island’s south. Pack reef shoes for some rocky shorelines and expect pleasant days with low chance of disruption.
