Mahé and Inner Islands
The main island of Mahé and nearby Praslin, La Digue host Victoria, the capital, under a classic tropical rainforest (Af) climate. Daytime highs hover at 29-31°C year-round, with nights cooling to 24-26°C. Rainfall totals 2,200-2,900 mm annually, peaking in the northwest trade wind season (November-April) with frequent showers, while May-October offers drier, sunnier days perfect for hiking Morne Seychellois or beach outings. High humidity (75-85%) enhances the lush vegetation but can feel muggy; sea breezes provide relief. Expats enjoy consistent warmth for water sports and nature exploration.
Lush, humid paradise with steady warmth, refreshing trade winds, and rainforest vibrancy—perfect for endless island living.
Outer Coral Islands
Remote outer atolls like Aldabra feature similar Af climate but slightly higher rainfall (up to 3,000 mm) due to exposure. Temperatures match the main islands at 26-30°C averages, with negligible variation. Drier periods align with trade winds, though isolation amplifies tropical downpours. Sunshine is plentiful, supporting pristine coral ecosystems. Fewer residents experience pure, unspoiled conditions ideal for eco-expats, though access is limited. Humidity remains high, fostering diverse wildlife amid consistent balmy weather.
Secluded tropical haven with abundant rain nourishing coral atolls, steady warmth, and ultimate serenity for nature lovers.
