Temperature in Sao Paulo in May

The 8°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset.

The UV index of 2 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Wind averages 16 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 72°F average high, 57°F overnight low.

Packing for Sao Paulo in May means dressing for 22°C days and 14°C evenings. A light cotton tee with a casual overshirt works well at 22°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 14°C, a modest 8°C drop that a light cardigan or denim jacket covers.

At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.

💡
