Barometric pressure

San Jose is located in the Santa Clara Valley. The valley is surrounded by mountains to the east and west. These mountains block winds from the Pacific Ocean. They also trap heat and moisture in the valley.

The blocked winds and trapped heat and moisture affect the atmospheric pressure. The pressure is usually highest in the winter months. It is lowest in the summer months. This is because cold air is denser than warm air.

The pressure can drop suddenly when storms come from the Pacific Ocean. The storms bring rain and wind to the valley. They also bring lower pressure. This can happen at any time of the year.
