Hourly Pressure Trends
Track the barometric pressure in San José hour by hour and stay informed about how it will change over the next 6 hours.
The barometric pressure in San José varies throughout the day. It can rise and fall rapidly due to the city's location. This fluctuation affects the weather patterns.
San José is surrounded by mountains to the north and east. These mountains block airflow from the Atlantic Ocean. This blocking effect causes air to rise, cool, and condense, resulting in cloud formation and precipitation.
The city's valley location also contributes to temperature variations. Cold air from the mountains flows into the valley, making nights cooler. Warm air from the Pacific Ocean moves into the valley, warming the city during the day.
The landscape's impact on atmospheric pressure leads to a tropical savanna climate. This climate is characterized by distinct dry and rainy seasons. The rainy season, from May to November, brings heavy rainfall and occasional flooding.
