February gets roughly 575% more precipitation than August — 270mm against 40mm. That difference, more than temperature, is what changes how a day here feels.
Daytime highs only move 5°C across the whole year (25–30°C), so timing matters far less here than rainfall does.
December gives you 13.3 hours of daylight against just 10.7 in June — a 3-hour difference in how much you can actually fit into a day.
August is the driest month at 40mm across roughly 3 wet days, while January peaks at 280mm.
July is almost as good as August, but usually quieter and cheaper. If your dates are flexible, it is the easier trip.
Reunion Island changes character completely through the year — August and February are effectively two different destinations. Pick the month that matches what you want to do, not the highest-rated one.
Ratings compare months within Reunion Island, not against destinations worldwide: five stars means the best time to be here, not that Reunion Island beats anywhere else. Tags describe what the conditions actually suit.

Each month in Reunion Island is described from long-run climate normals and then rated relative to the other eleven months in the same city. A five-star January in a cold destination means January is one of the best times to be there — not that it beats a Mediterranean summer.
| Factor | Weight | What it measures |
|---|---|---|
| Temperature | Described | Average daytime high and overnight low for the month, shown as measured rather than judged. |
| Precipitation | Described | Monthly millimetres and wet-day count, labelled as snow or rain/snow where temperatures make that the likely phase. |
| Sunshine & daylight | Described | Average daily sunshine hours and astronomical daylight length at mid-month, from the city’s latitude. |
| “Best for” tags | Derived | Applied only when the conditions genuinely support the activity — snow depth-friendly cold for skiing, 13–24°C and low rain risk for hiking, dark evenings at high latitude for aurora. A month with few strong use cases gets fewer tags rather than padded ones. |
| Star rating | Relative | Ranks the month against the other eleven months in the same city. Never a comparison between cities. |
Figures are long-run climate averages, not a forecast for a specific year. Where a month lacks sourced rainfall or humidity, the value is modelled from temperature range and rain frequency.
