Causes and Factors

The distinct precipitation pattern in São Paulo is primarily attributed to the city’s location in the subtropics, which causes a convergence of warm, moist air from the Atlantic Ocean and relatively cooler, drier air from the interior of the continent. During the wet season, when the city is situated on the edge of the Intertropical Convergence Zone (ITCZ), a low-pressure system that brings heavy rainfall to the tropics, São Paulo experiences frequent thunderstorms and prolonged periods of drizzle. In contrast, during the dry season, the ITCZ shifts northward, resulting in drier conditions and less frequent rainfall. Additionally, the presence of the Serra do Mar mountain range to the east of the city plays a role in enhancing precipitation, as it forces moist air to rise and cool, leading to condensation and rainfall.

Seasonal Variations

Rainfall in Sao Paulo, Brazil, exhibits distinct seasonal variations, influenced by the city’s subtropical climate. During the austral summer (December to March), rainfall is abundant, with frequent thunderstorms and torrential downpours. This is primarily due to the influence of the Intertropical Convergence Zone (ITCZ), a global wind belt that brings moist air and precipitation to equatorial regions.

Annual Totals and Distribution

Sao Paulo receives an average annual rainfall of around 1,300 millimeters (51 inches). The rainfall distribution is uneven throughout the year, with the wet season (October to April) accounting for approximately 75% of the total precipitation.

This event was captured in photographs and became a memorable chapter in the city’s history.

Atmospheric Conditions

For snowfall to occur in Sao Paulo, several atmospheric conditions must align. The temperature must drop significantly below freezing point, which is uncommon in this warm climate. Additionally, moist air from the ocean must rise and condense into clouds, creating a cold and humid environment. Finally, specific wind patterns must facilitate the formation of snowflakes and their descent to the ground. The combination of these factors is exceptionally rare in Sao Paulo, making snowfall an infrequent occurrence.

Humidity in Sao Paulo

Sao Paulo, Brazil is a bustling metropolis known for its tropical climate. The city experiences high humidity levels throughout the year, with an average annual relative humidity of around 75%. The humidity is especially pronounced during the summer months (November to March), when it can reach up to 90%. The combination of high temperatures and humidity can make it feel uncomfortably muggy and oppressive.

The high humidity in Sao Paulo is primarily due to the city’s location near the Atlantic Ocean and the surrounding rainforest. Prevailing winds from the ocean carry moisture inland, contributing to the city’s humidity levels. Additionally, the city’s sprawling urban landscape, with its abundance of buildings and paved surfaces, can trap heat and moisture, further exacerbating the humidity problem. The lack of strong winds within the city also prevents the dispersal of accumulated moisture, leading to a buildup of humidity in the air.

Wind Patterns in Sao Paulo

These winds are particularly strong during the summer months (December-March) when the city is hottest and most humid. During the winter months (June-September), winds tend to be weaker and more variable in direction.

Influence on Weather Conditions

The predominant northeasterly winds play a significant role in shaping the weather conditions in São Paulo. They carry moisture from the ocean, which contributes to the city’s frequent rainfall. Additionally, these winds help to moderate the temperature, preventing extreme heat during the summer months. However, during the winter, stronger winds can bring colder air and increased cloud cover, leading to a drop in temperatures. The wind also affects air quality, as it helps to disperse pollutants, resulting in improved air conditions. Overall, the prevailing winds in São Paulo are a defining factor in the city’s climate, influencing temperature, humidity, rainfall, and air quality.
