May in São Paulo marks a pivotal shift in the city’s annual weather cycle, transitioning from the warmth and humidity of summer into a drier, more temperate season. This period is often characterized by mild days, cooler evenings, and a significant reduction in rainfall compared to the preceding months. As the peak of the rainy season begins to wane, the atmosphere feels fresher, making it an ideal time for outdoor activities and exploration.
Temperature and Climate Overview
During May, average daytime temperatures typically range between 19°C and 22°C (66°F to 72°F), providing a comfortable environment for residents and visitors alike. Nighttime temperatures can drop to around 12°C (54°F), necessitating a light jacket or sweater. The city experiences a decrease in both humidity and average high temperatures compared to the summer months, creating a more pleasant climate overall.

Layering is key when preparing for São Paulo’s May weather.

The city enjoys a significant amount of sunshine during May, with clearer skies becoming the norm. Daylight hours gradually decrease as the month progresses, but there is still ample time for sightseeing and outdoor dining.
