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 São Paulo 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 São Paulo linked below.
July, at 87/100. It combines very low rain risk with 22°C afternoons and roughly 16°C evenings, which is the most forgiving combination São Paulo offers for seated guests.
February scores 35/100: 28°C highs, 217mm of rain over about 18 days and 22°C evenings make a fully outdoor plan fragile.
In July rain falls on roughly 2 of 30 days, so the single-day probability is about 7%. In February that rises to about 60%.
A marquee on standby is usually enough in July, where rain risk is very low. Outside the 6 months scoring 65 or higher, book real covered space.
July gives 10.7 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.
