The barometric pressure in Los Angeles is influenced by its proximity to the Pacific Ocean and the surrounding mountain ranges. It tends to be relatively high during the summer months. This is because the high pressure system from the Pacific Ocean dominates the region. In the winter months, the pressure tends to be lower due to the influence of low-pressure systems from the Gulf of Alaska.
Los Angeles is situated in a coastal basin surrounded by mountains. The San Gabriel Mountains are to the east and the Santa Monica Mountains are to the west. The city's landscape affects the atmospheric pressure in several ways. The mountains block or redirect winds, which in turn influence the pressure patterns. The coastal location also means that the city is exposed to the moderating influence of the ocean.
