Five distinctive coasts, one reef-fringed Mauritius dive trip
When to go
Year-round island visits are possible, but coast and activity decide whether a particular day works.
Best overall window
A balanced multi-coast window: April-May transitions and relatively dry Sep-Oct; November gets warmer but lies inside the official cyclone season. Check each coast before a boat day.
Outside that window
Storm Disruptions.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
| Scope | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Overall | Overall - Jan: More variable | Overall - Feb: More variable | Overall - Mar: More variable | Overall - Apr: Best | Overall - May: Best | Overall - Jun: Good | Overall - Jul: Good | Overall - Aug: Good | Overall - Sep: Best | Overall - Oct: Best | Overall - Nov: Best | Overall - Dec: Good |
These regional shifts apply only to the selected scope.
| Area | Best months | Why it changes |
|---|---|---|
| Grand Baie, Trou aux Biches and Pereybere | Apr-May and Sep-Nov | Northern and northwestern operator bases include Grand Baie, Trou aux Biches and Pereybere. Main caution: Peak holiday weeks feel busier and book faster. |
| Flic en Flac and Tamarin | Apr-May and Sep-Nov | The west is leeward of common southeast trades, especially useful when the east is choppy. Main caution: Same-day route swaps become more likely when weather builds. |
| Le Morne and La Gaulette | Apr-May and Oct-Nov for mixed activity | Le Morne lagoon and pass are distinct environments: prevailing southeast trades favor kite sports but may complicate shore and boat activity. Main caution: Wind Exposed Departures. |
| Blue Bay, Mahebourg and Pointe Jerome | Apr-May and Sep-Nov with marine-park authorization | Blue Bay is a regulated marine park, not a free-roaming reef. Main caution: Surface chop can add a little more texture on exposed entries. |
| Belle Mare and Poste de Flacq | Apr-May and Oct-Nov for less trade-wind chop | East coast is exposed to persistent southeast trades around May-October. Main caution: Wind Exposed Departures. |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
Humpback whale migration (observation only)
Best for Topside
Jul to Nov
Mauritius Now gives July-November as an indicative migration-viewing season off the west.
Sperm whales off west coast (viewing only)
Best for Topside
Year-round
Tourism sources describe possible sperm whale sightings through the year off the west coast.
Coral-reef fish and occasional turtles
Best for Snorkel, Scuba
Year-round
Reef fish occur around mainland reefs and Blue Bay; turtles may be seen but specific months, abundance and water quality are not reliable enough to claim a peak.
