What São Paulo Is Like in May: Weather Conditions and Daily Feel
May in São Paulo feels like a genuine exhale after the heavy rains of late summer. Skies shift from overcast and cloudy to cleaner and brighter, mornings have a crisp bite, and afternoons are mild and sunny — the kind of weather that makes café-hopping or wandering Ibirapuera Park genuinely enjoyable.
Evenings cool down quickly. If you’re used to tropical destinations, the 14–16°C nights may catch you off guard. Sightseeing on foot is comfortable during the day, but carry a layer once the sun drops. Walking between neighborhoods — Vila Madalena, Pinheiros, Jardins — is notably easier than in January or February, when heat and rain often complicate plans.
Average High and Low Temperatures in São Paulo in May
The average high temperature in May sits around 23°C to 25°C — warm in the sun, comfortable in the shade. The low temperature overnight reaches 14–16°C (57°F). That’s a meaningful range within a single day, and it catches underprepared visitors off guard.
High temperatures don’t peak in May the way they do earlier in the year — summer highs can touch 28°C or more in February. May is the beginning of the transition, not an extreme. Brazil’s national meteorological service (INMET) compiles historical monthly weather data from weather stations across the city for reference.
Precipitation and Rainfall in São Paulo During May
May marks São Paulo’s shift into its dry season. The average rainfall — and overall precipitation — drops significantly compared to the preceding months. Expect roughly 70–80mm across the month, spread across 8–10 rainy days, according to climate data from Climate-Data.org.
The march to may period sees precipitation declining steadily, and by mid-May the pattern is well established. The average rainfall is low by São Paulo standards. Rain, when it arrives, tends to be brief afternoon or early evening showers. A compact umbrella is practical insurance. Flash flooding — a genuine risk in summer — is rare this time of year.
Humidity in São Paulo in May
Humidity in May is moderate and noticeably more comfortable than the humid peak of the summer months. It won’t feel oppressive. The heat index is relatively benign — what you feel is close to what the thermometer reads.
Travelers who find high humidity draining (common feedback from those visiting between December to February) typically find São Paulo during May far more manageable. The drier air can occasionally irritate sinuses, but for most visitors this is a non-issue.
Sunshine and Cloudy Days: São Paulo Weather in May

Wind speed is generally low throughout the city in May — it’s not a blustery month. Conditions are calm enough for outdoor dining and open-air attractions. The NASA MERRA-2 reanalysis dataset provides hourly temperature and average daily weather data for São Paulo throughout the year for those who want deeper climate modelling.
Is São Paulo Busy in May? (Tourism Levels)
