Hourly Pressure Trends
Track the barometric pressure in São Paulo hour by hour and stay informed about how it will change over the next 6 hours.
São Paulo's barometric pressure is generally high, ranging from 1010 to 1020 hPa. This is due to its inland location and proximity to the Atlantic Ocean.
The city is surrounded by the Serra do Mar mountain range to the east and the Serra da Mantiqueira to the north. This mountainous landscape affects the atmospheric pressure, creating a rain shadow effect. The mountains block moisture-laden air from the ocean, resulting in lower humidity and pressure.
The city's terrain is relatively flat, with an average elevation of 760 meters above sea level. This flatness allows cold fronts from the south to move easily into the region, bringing cooler air and changes in pressure. The region's topography also contributes to the formation of fog, especially during winter months.
