The barometric pressure in Costa Mesa is influenced by its coastal location. The pressure is higher during the day and lower at night. This variation is due to the city's proximity to the Pacific Ocean.
The city is surrounded by hills to the north and east. These hills block cold air from flowing into the city. The Santa Ana Mountains are located about 20 miles east of Costa Mesa. The mountains also play a role in shaping the local weather patterns.
The coastal landscape allows for a gentle influx of marine air. This air brings moisture and cools the city. The surrounding hills and mountains force the air to rise, resulting in a slight increase in pressure. This unique combination creates a microclimate in Costa Mesa.
