Healdsburg Weather
Town • San Francisco Bay Area
Healdsburg grew up around a 19th-century town plaza on the Russian River in northern Sonoma County. It sits where the Russian River, Dry Creek, and Alexander valleys meet. The plaza is lined with shops, restaurants, galleries, and tasting rooms, and dozens of wineries fill the surrounding valleys. Just south of downtown, below the steel-truss Memorial Bridge, Sonoma County Regional Parks runs Healdsburg Veterans Memorial Beach, a sandy river beach with a summer swimming area.

Healdsburg sits right at the edge of the summer fog's reach. The marine layer, the low sheet of fog and cloud that forms over the cold ocean, cools the Russian River Valley. It rolls up the river canyon from Jenner and across the Santa Rosa Plain. On some summer mornings it reaches town and leaves the plaza gray and damp until mid-morning. A few miles north, around Geyserville in the Alexander Valley, the fog arrives a little less often.

What shapes Healdsburg's weather
When Healdsburg's morning gray burns off, afternoons heat up quickly on the low river flats. The evening sea breeze is what finally cools the town, and the drop from afternoon to night is large. On clear, calm nights in winter and spring, cold air drains off Fitch Mountain and the hills north of town. It settles along the river and brings frost to the low vineyards.
Winter weather in Healdsburg centers on the Russian River. Heavy rain over the upper watershed in Mendocino and northern Sonoma counties sends the river up fast. The National Weather Service keeps a forecast gauge on the Russian River at Healdsburg. In fall the main hazard is wind, when dry northeast winds off the Mayacamas Mountains can drive fire toward the Highway 101 corridor. In October 2019 the Kincade Fire led to an evacuation order for all of Healdsburg.
Tips for visiting Healdsburg
Swim when the lifeguards are on
Healdsburg Veterans Memorial Beach is staffed from Memorial Day weekend through Labor Day, and a temporary summer dam creates a swimming area from July through Labor Day.
Get to the beach before midday
On summer weekends the beach parking area can fill by mid-day, and off-street parking nearby is limited.
Keep dogs off the sand
Leashed dogs are allowed on the beach park's lawn and in the parking lot, but not on the beach or in the river.
Check the river gauge after storms
The Russian River at Healdsburg forecast shows when the river is nearing flood stage. Check it before winter river walks or paddles.
Bring a jacket for summer mornings
Misty mornings are part of a Russian River summer, and the plaza can feel cool until the marine layer lifts.
Healdsburg through the seasons
- Spring (March–May)
- Spring brings green hills and budding vines across all three valleys, and frost is a risk on clear nights along the river.
- Summer (June–August)
- Summer brings some gray mornings, hot afternoons, and the busy beach season, with lifeguards on duty and the summer dam in place at Memorial Beach.
- Fall (September–November)
- Fall is harvest season and the time of dry offshore winds, which blow from inland toward the coast. The Kincade Fire forced the town's evacuation in October 2019.
- Winter (December–February)
- Winter is the rainy season, when the Russian River can rise quickly after heavy storms upstream.
Activities and the weather that matters
- River swimming and paddling: Best on hot summer afternoons when lifeguards are on duty. Cold, fast water after winter storms makes the river unsafe.
- Wine tasting on the plaza and in the three valleys: Downtown tasting rooms suit any weather. Drive north into the Alexander Valley if Healdsburg is still gray at midday.
- Hiking in and around town: Go early on summer days before the heat, or on clear afternoons in spring and fall.
