Redwood Regional Park Weather
Park • San Francisco Bay Area
This 1,833-acre redwood canyon lies a few miles over the ridge from downtown Oakland. The East Bay Regional Park District renamed it Dr. Aurelia Reinhardt Redwood Regional Park in 2019. Its coast redwoods regrew after the forest was logged for Bay Area building in the mid-1800s. Redwood Creek runs down the canyon floor in the San Leandro Creek drainage, home of the trout strain that gave rainbow trout their name. Staging areas line Skyline Boulevard on the ridge above, and Redwood Gate on Redwood Road is the main entrance.

The park is a canyon on the inland side of the Oakland hills. The West Ridge above it is the first high ground that summer marine air meets after crossing the bay. On many summer mornings the ridge and the Skyline Gate trailheads are wrapped in cloud while the canyon below sits under a gray ceiling. That steady summer moisture is part of why coast redwoods thrive here and not on the drier hills farther east.

What shapes Redwood Regional Park's weather
Down on Stream Trail, shade and the creek keep the canyon floor cool even on warm afternoons, and cold air settles there on clear nights. The East Ridge Trail is the opposite, with chaparral and grassland facing Moraga and Mount Diablo. It is sunnier and warmer once the cloud lifts, and more exposed to the wind.
Redwood Regional Park's position close to the bay keeps it far milder in summer than Moraga, only a couple of miles east. Winter storms drop more rain on these hills than on the flatlands near the bay. Fire risk peaks in fall, when dry offshore wind crosses the ridge.
Tips for visiting Redwood Regional Park
Don't count on cell service
The Park District warns there is little or no cellular service in the park. Download a map before you go.
Pick canyon or ridge by the weather
On gray summer mornings the canyon trails stay sheltered and cool. On clear days, the East Ridge Trail has sun and long views.
Leave the fishing gear at home
Fishing is not allowed in the park, even though its creeks are rainbow trout habitat.
Check the alerts page for weather closures
The park district says some trails and park areas may be temporarily closed for weather conditions, park projects, habitat restoration, or repairs. Check its Alerts & Closures page before you go.
Redwood Regional Park through the seasons
- Spring (March–May)
- The creek runs strong and the canyon is lush. The fishway interpretive site near Redwood Gate tells the story of trout heading upstream to spawn.
- Summer (June–August)
- In summer, cloud-cooled mornings on the ridge and deep shade in the canyon make this one of the coolest hikes in the East Bay during inland heat waves.
- Fall (September–October)
- Fall brings clearer days, and September is as warm as any month. Dry offshore wind raises fire danger on the ridges until the first rain.
- Winter (November–February)
- Winter is wet, muddy, and dim under the redwoods. Redwood Gate keeps its shortest hours, 8 a.m. to 6 p.m., from November through February.
Activities and the weather that matters
- Canyon hiking on Stream Trail: Stream Trail is good in almost any dry weather. The shade makes it a hot-day escape, while heavy rain leaves it muddy.
- Ridge loops: With nearly 40 miles of trails, including sections of the East Bay Skyline National Trail, ridge loops are best on clear days, when the summer cloud has lifted.
- Horseback riding: Piedmont Stables offers boarding and lessons. Firm trails on dry spring and fall days are best for horses.
