Best Time to Visit the Indian Ocean: A Month-by-Month Calendar
The Maldives, the Seychelles, Mauritius and Sri Lanka run on monsoons that arrive at different times — which means somewhere in the ocean is always in season.

The short version
There is no bad month in the Indian Ocean, only a wrong island for the month. The Maldives is driest and calmest from December to April. Mauritius is at its best from May to December, when the Maldives is wetter. The Seychelles sits between two monsoons and is best in the changeover months — April, May, October and November. Sri Lanka effectively has two coasts with opposite seasons: the south and west from December to March, the east from May to September.

Booking windows that actually matter
- Christmas and New Year in the Maldives or the Seychelles: book by June; the best water villas and private islands go a year ahead.
- February and March in the Maldives: six months, with minimum-stay rules over the peak.
- July and August in the Maldives: the value window, often bookable eight weeks out.
- Seaplane transfers stop at dusk in the Maldives — arrive before mid-afternoon or plan an overnight in Malé.
- Diving and manta trips follow the monsoon from one side of an atoll to the other; ask the dive centre before choosing a resort for a specific season.
Frequently asked questions
- What is the best month to visit the Indian Ocean?
- February for the Maldives and Sri Lanka's south coast, and April, May, October or November for the Seychelles. Mauritius is at its best from May to December.
- When is the rainy season in the Maldives?
- The south-west monsoon runs roughly May to November, bringing wetter, breezier spells rather than continuous rain. December to April is the dry season, with the calmest seas and best visibility.
- When is cyclone season in Mauritius?
- November to April, with the highest risk from January to March. May to December is the reliable window, and it is also the drier and less humid half of the year.
- When is the cheapest time to visit the Indian Ocean?
- June and July in the Maldives and the Seychelles, when the monsoon reduces rates sharply while the sea stays warm. Avoid Christmas and New Year, the most expensive weeks of the year by a wide margin.
Editorial note & limitations
