Volcanic reef diving, serious apnea and carefully regulated lagoons on Reunion's west coast.
When to go
May-November is the longer dry period identified by Meteo-France, with April and December often transitional and January-March more reliably wet.
Best overall window
Month bands follow the primary meteorological authority, not invented dive visibility measurements.
Outside that window
April and December alternate between wet and dry patterns; check alerts and daily boat conditions.
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: Good | Overall - May: Tradeoffs | Overall - Jun: Tradeoffs | Overall - Jul: Tradeoffs | Overall - Aug: Tradeoffs | Overall - Sep: Tradeoffs | Overall - Oct: Tradeoffs | Overall - Nov: Tradeoffs | Overall - Dec: Good |
These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
Humpback whale passage versus regulated encounter season
Best for Topside, Scuba, Snorkel
Jun to Oct
Whales are seasonally reported along the western coastline from June-October, but regulated close approaches and guided water-entry for humpbacks are limited to July-September under the prefecture's 2026 guidance.
Year-round reef turtle possibility
Best for Scuba, Snorkel, Topside
Year-round
Reef turtles are a documented conservation and natural-history theme, with no defensible month-specific guaranteed sighting claim.
Built from climate references, access rules, and destination operators. Wildlife timing and route flexibility can shift year to year.
