Air pressure helps shape the weather. In summer, high pressure over the Pacific Ocean often blocks storms and keeps skies clear. In winter, lower pressure systems move in from the Pacific and bring clouds, wind, and rain. Cool marine air can also move inland from San Francisco Bay, causing cloudy mornings or light fog.
Mountain View sits near the southern end of San Francisco Bay, between the Pacific Ocean and the Santa Cruz Mountains. The bay helps keep temperatures from becoming too hot or too cold. The mountains can block or weaken storms and help create different weather in nearby areas. Winds often move through the valley and become stronger near the hills.
Seasonal changes are gradual. Spring brings warmer days and occasional rain. Summer has long dry periods, with warm afternoons and cooler nights. Fall is often sunny and mild, though the first rains may arrive late in the season. Winter brings the coolest temperatures, more clouds, and most of the year's rainfall.
