Recurring seasonal events, natural spectacles, closures and holidays — curated and sourced.
- Season
The south-east trades
15 May – 31 Oct · usuallyWind seasonThe trade winds blow through the winter and the island reorganises around them. Grand Baie sits on the sheltered north coast, which is why the dive boats and the island-hopping trips leave from here.
- Nature
Humpbacks off the west coast
1 Jul – 31 Oct · usuallyWhale seasonHumpbacks pass along the west coast through the winter, and the boats that go out to them leave from Black River, an hour and a half down the coast rather than from Grand Baie itself.
- Festival
Diwali
15 Oct – 15 Nov · usuallyMauritius keeps Diwali properly: clay lamps and paper lanterns down every street in the Hindu villages, sweets handed over the fence, and a public holiday the day after. Source ↗
