August keeps seated guests at 25°C in the afternoon and around 20°C after sunset — the closest Reunion Island gets to a ceremony that needs neither shade structures nor patio heaters.
Rain falls on roughly 3 days in August (very low risk, 40mm). A simple marquee-on-standby is usually enough.

Wedding weather is scored differently from travel weather: seated guests in formalwear tolerate a narrower band than sightseers, and the ceremony hour matters more than the daily average. Each month in Reunion Island is scored 0–100 on the weighting below.
| Factor | Weight | What it measures |
|---|---|---|
| Dry conditions | 38% | Share of days with measurable rain — the single factor most likely to force a backup plan. |
| Guest comfort | 27% | Distance from a 22°C daytime ideal, with an extra penalty for humid heat above 24°C. |
| Evening temperature | 20% | Modelled reception-hour temperature against an 18°C ideal for an outdoor evening. |
| Photo light | 15% | Sunshine hours and daylight length, which set the length and quality of the golden hour window. |
Based on long-run climate averages rather than a forecast. Plan the ceremony around the golden hour — see golden hour times for Reunion Island linked below.
August, at 81/100. It combines very low rain risk with 25°C afternoons and roughly 20°C evenings, which is the most forgiving combination Reunion Island offers for seated guests.
February scores 28/100: 30°C highs, 270mm of rain over about 23 days and 25°C evenings make a fully outdoor plan fragile.
In August rain falls on roughly 3 of 30 days, so the single-day probability is about 10%. In February that rises to about 77%.
A marquee on standby is usually enough in August, where rain risk is very low. Outside the 4 months scoring 65 or higher, book real covered space.
August gives 11.3 hours of daylight and about 8 hours of direct sun. Put portraits in the final 60–90 minutes of daylight so they land inside golden hour rather than after it.
