What shapes Forestville's weather
The Russian River is Forestville's cooling route. The valley's winegrowers say the river plays a large role in pulling in fog and cooling breezes. On summer evenings, ocean air pushes up the canyon from Jenner and spreads east past town. Fog also drifts north across the Laguna de Santa Rosa lowlands. Many summer mornings start gray, then clear by late morning.
Clear winter nights let cold air drain onto the river flats and low farmland around town. In big winter storms the Russian River rises fast, and low river roads and beaches nearby can flood.
Tips for visiting Forestville
Swim with a life vest
Steelhead Beach has no lifeguards, but free loaner life vests are on the beach in summer.
Arrive early on hot weekends
The Steelhead Beach entrance closes temporarily when the lot fills on busy summer weekends.
Pick your river beach
Sunset Beach River Park, Steelhead Beach Regional Park, and Mom's Beach all give access to the Russian River.
Ride the bus from Santa Rosa
Sonoma County Transit buses connect Forestville with Sebastopol and Santa Rosa.
Bike or walk the West County Trail
The 5.5-mile, mostly paved trail runs from downtown Forestville through Graton to Sebastopol.
Forestville through the seasons
- Spring (March–May)
- Spring brings mild days and a high, cold river. The Steelhead Beach launch for larger boats stays open through mid-May.
- Summer (June–August)
- Summer often starts the day foggy and turns warm by afternoon. The river pulls in the fog and breeze that keep nights cool.
- Fall (September–October)
- Fall is harvest season in the surrounding vineyards, with warm, often clear days. Dry offshore winds, which blow from the hot interior toward the coast, can bring fire weather and smoke.
- Winter (November–February)
- Winter is the rainy season. Watch river forecasts in big storms, since low riverside roads and beaches can flood.
Activities and the weather that matters
- River swimming and tubing: Best on hot summer afternoons after the fog clears. Steelhead Beach is a recommended launch for tubing trips, and dogs must stay leashed even while swimming.
- Canoeing and kayaking: Paddlers can launch from the Steelhead Beach sand year-round. Calm days with moderate flow are best. Skip high, muddy water after storms.
- Cycling the West County Trail: The county parks department calls spring and fall especially pleasant. Summer mornings are cooler than afternoons.
- Wine tasting: Good year-round. Vineyards on Laguna Ridge, just south of the river near Forestville, are known for cool temperatures and Pinot Noir.
