Forecast

Walnut Creek is situated in a valley surrounded by the Diablo Range to the east and the San Francisco Bay to the west. This unique landscape creates a microclimate, where the air is trapped and circulated within the valley. The surrounding mountains block or redirect winds, causing the air pressure to rise or fall. As a result, the barometric pressure in Walnut Creek is distinct from the surrounding areas.
