San Pablo Weather
Town • San Francisco Bay Area
San Pablo is a small, densely built city on the low plain between the foot of the Berkeley Hills and San Pablo Bay, largely ringed by Richmond. Wildcat Creek and San Pablo Creek cross it on their way from the hills to the bay, and San Pablo Avenue and Interstate 80 run through it. Contra Costa College sits on Mission Bell Drive, and the regional parkland of Wildcat Canyon and the Point Pinole shoreline are both a short drive away.

What shapes San Pablo's weather
The hills just east of San Pablo, the northern end of the ridge that holds Wildcat Canyon, catch the marine layer. That is the cool, moist ocean air that forms low summer cloud. On many summer mornings the low cloud covers San Pablo. At the same time the San Pablo Reservoir valley and El Sobrante, on the far side of that ridge, are already in sun.
Winter is the season to watch the creeks. Wildcat and San Pablo creeks drain the hills above town and rise quickly in heavy storms on their way through the flats to the bay. As in Richmond, the wind direction also decides which neighborhoods lie downwind when a refinery or industrial incident triggers a county shelter-in-place alert.
Tips for visiting San Pablo
Hike into Wildcat Canyon from Alvarado
The Alvarado Staging Area off McBryde Avenue, just southeast of town, leads into the creekside forest. Next to it, Alvarado Park has picnic areas and historic stonework.
Head to Point Pinole for the bay
The shoreline park next to San Pablo has bluffs, beaches and about twelve miles of trails on San Pablo Bay. Dogs aren't allowed on the pier.
Watch park hours in winter
Point Pinole closes at 4 p.m. in November and December, compared with 7 p.m. from May through September.
Sign up for county alerts
Contra Costa County's Community Warning System sends shelter-in-place and evacuation alerts to West County neighborhoods.
San Pablo through the seasons
- Spring (March–May)
- The hills above town are green, creeks are still running, and the afternoon breeze builds again by May.
- Summer (June–August)
- Summer mornings are often gray under the marine layer. Afternoons turn sunny and breezy, a little warmer than on the Richmond shoreline.
- Fall (September–October)
- September usually brings San Pablo's warmest weather. The park district may close nearby hill parks such as Wildcat Canyon during Red Flag Warnings, the weather service's alerts for hot, dry, windy fire weather.
- Winter (November–February)
- Winter is the rainy season, when Wildcat and San Pablo creeks run high. Short days mean early closing at Point Pinole.
Activities and the weather that matters
- Hiking Wildcat Canyon: Fire roads climb onto open, sunny ridges that are best on clear spring and fall days. The creek trail stays cooler in summer.
- Walking at Point Pinole: The park's bluffs and eucalyptus woods are breezy in summer. Calm spring and fall days are the best for a long walk.
- Picnics at Alvarado Park: The shady creekside picnic areas are comfortable on warm afternoons and damp after rain.
