What to do in Mauritius on a rainy day
A rainy day in Mauritius is rarely a lost day. First, it seldom rains everywhere at once: the west coast gets less than half the rain that falls on the central plateau. Second, the island has plenty of indoor options: an oceanarium, Port Louis museums, sugar estates, a rum distillery and a tea factory. Here is how to read Mauritian weather and where to go depending on where you are staying.
First move: switch coasts
The trade winds blow from the south-east and hit the mountains, so the east, the south and the central plateau catch most of the rain while the west stays sheltered. The 1971-2000 normals of the Mauritius Meteorological Services make it clear: about 780 mm a year and 64 rainy days (over 1 mm) at Médine on the west coast, against nearly 2,000 mm and 179 days at Vacoas on the plateau, and about 1,960 mm and 173 days at Fuel in the east. The north (Pamplemousses) sits in between with about 1,350 mm and 148 days.
In the southern winter the gap is huge: in July, Médine averages 3 rainy days and Vacoas 17. If the sky is grey at Belle Mare or Curepipe, an hour's drive to Flic en Flac, Tamarin or Le Morne is often enough to find the sun again.
When does it rain most?
According to the Mauritius Meteorological Services, summer (November to April) brings about two thirds of the year's rain. February and March are the wettest months, October the driest. The island averages 6.5 to over 8 hours of sunshine a day, less in the uplands than on the coast.
November to April is also cyclone season. In case of a warning, follow the Meteorological Services website or the information lines 8996 from a landline and 171 from a mobile, as listed in French consular advice. The authorities can order a lockdown lasting two to three days.
Port Louis: a full day under cover
The capital is the best bet on a grey day. Odysseo, the Mauritius oceanarium, shows more than 200 Indian Ocean species in 45 tanks and opens 9am-5pm. Ten minutes' walk away, the Caudan Waterfront has shops, restaurants and the Blue Penny Museum (closed on Sundays), home of the famous "Post Office" stamps.
The Central Market is covered: head upstairs for a dholl puri. The free Intercontinental Slavery Museum opens Monday to Friday 9.30am-5pm and Saturday 9.30am-2pm. Nearby Aapravasi Ghat has an indoor interpretation centre.
In the north: sugar, rum and a colonial mansion
L'Aventure du Sucre in Pamplemousses tells the island's sugar story inside a former factory, with a new interactive tour opened in 2026. Château de Labourdonnais, an 1859 mansion, can be visited inside and includes a tasting of rums and fruit pastes.
For families or a late afternoon, La Croisette shopping centre in Grand Baie has an air-conditioned cinema and food court.
In the south-west and centre
In Chamarel, Curious Mauritius (mirror maze, upside-down house, escape room) opens daily 9.30am-5pm. The Chamarel Rum Distillery, closed on Sundays, offers tours of its distillery. A bonus: the Seven Coloured Earths look brightest just after a shower, and Chamarel Waterfall is at its most powerful in the rainy season.
On the plateau, Eureka House in Moka can be enjoyed from its covered veranda, and Bagatelle Mall is a handy break. In the south, the Bois Chéri tea plantation (factory working on weekday mornings) and the Rault biscuit factory near Mahébourg (Monday to Friday, 9.30am-3pm) are two unusual indoor visits.
What to avoid in the rain
Postpone hikes: Le Pouce, Lion Mountain or Black River Peak turn slippery and muddy, and the summits disappear in cloud. Skip Tamarind Falls too, whose trails are slippery even in fine weather.
Boat trips are often cancelled when the sea is rough, so book them with a day or two of margin. The plateau viewpoints (Black River Gorges, Trou aux Cerfs) are then often in the clouds.
