San Ramon is a city in Contra Costa County, California, United States, located within the San Ramon Valley, and 34 miles east of San Francisco. San Ramon's population was 84,605 per the 2020 census, making it the 4th largest city in Contra Costa County, behind Concord, Richmond and Antioch.
Geography
Mount Diablo flanks the city to the northeast and is prominently visible from almost all parts of the city. The Las Trampas Regional Wilderness borders San Ramon's extreme northwest, at the northern end of Bollinger Canyon. The smaller Bishop Ranch Regional Preserve straddles San Ramon's western border, located approximately between Interstate 680 and the Alameda County line.
The topography of San Ramon is varied, featuring a mix of the rolling hills of the Diablo Range and the flatter basin of the San Ramon Valley. The city is predominantly urban and residential with many new housing developments; however, much of the land around the city's perimeter regions remains undeveloped, and is covered by grasslands and oak tree orchards. During the drier months the grasses are golden, but with the precipitation of winter and spring, the grasses turn green.
Climate
San Ramon's weather typifies a Mediterranean climate, seasonal, and moderate. Summers can range from warm to hot and dry, while winters are mild or cool, wet and rather short.[14] Its weather is similar to the adjacent cities of Danville, Dublinand Pleasanton. Fog can be infrequent but occurs normally in the western reaches of the city, at the eastern mouth of Crow Canyon, through which marine weather patterns funnel in from the San Francisco Bay via Castro Valley. It usually burns off by mid-to-late morning.
