When to go

Best time to visit Mahé

Mahe's best allround windows usually fall in the intermonsoon periods, especially March to May and October to November, when winds weaken and the sea becomes friendlier for diving, snorkeling, and boatbased freediving.

Best overall window

March to May and October to November

Lighter winds, calmer seas, and warm water around 28°C to 29°C.

Outside that window

Southeast trades often reach 25 km/h to 35 km/h and can make openwater plans rougher.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
