São Paulo Weather in May

São Paulo's subtropical highland climate at 760 meters elevation gives it milder temperatures than coastal Brazilian cities, but the world's fourth-largest urban area has created an extreme urban heat island that raises city temperatures 5–10°C above surrounding rural areas. Summers are hot and wet with torrential afternoon downpours and flash flooding in low-lying areas, while winters are dry and cool with occasional cold fronts from the south. The city's explosive growth has replaced most natural vegetation, creating intense heat and poor ventilation.

One of the most popular travel months worldwide for good reason.

São Paulo sits at 2,500 feet (760m) elevation, making it cooler than its tropical latitude would suggest. The city receives substantial year-round rainfall. Winters (June–August) are the dry season with mild, clear weather. Summers bring intense afternoon thunderstorms.
