Season planner for Praslin and La Digue
Weather is the whole game here. Seychelles shifts between the wetter northwest monsoon from roughly December to March, the stronger southeast trades from May to September, and calmer transition periods around April and October to November. For most water users, the sweet spot is the shoulder between those systems: smoother seas, easier ferry rides, and more site choice for dive boats. Water generally stays warm at about 26°C to 29°C all year. Topside travelers can enjoy the islands in any month, but June to August often feels best for hiking and cycling if you do not mind windier coasts and rougher seas.
