Bolinas Weather
Town • San Francisco Bay Area
Bolinas sits at the southern tip of the Point Reyes peninsula, on the west side of the San Andreas Fault. Bolinas Lagoon lies on one side and the open Pacific on the other. The village is small and unincorporated. Much of it spreads across a low marine terrace called the Big Mesa, which ends at Agate Beach and the Duxbury Reef tidepools. Unlike Stinson Beach across the lagoon mouth, it has no mountain at its back. A small local utility district, not a city, provides its water, sewer and parks.

Bolinas is the most exposed town on this stretch of coast. The Big Mesa is low and flat and faces open ocean on the south and west. The northwest wind and the summer marine layer, the sheet of cool, damp ocean air that brings fog, come straight off the water with nothing to slow them. Stinson Beach, two miles east across the lagoon mouth, has Mount Tamalpais to block some of the wind. Bolinas has only Bolinas Ridge, well back across the lagoon.

What shapes Bolinas' weather
In summer, cold water that wells up from the deep ocean just off Bolinas keeps the fog thick and the afternoons breezy. Gray mornings that clear only partly, or not at all, are normal from late spring through August, and the wind tends to strengthen through the afternoon. A few blocks make a difference here. The village by the lagoon is a little more sheltered than the bluff tops on the mesa.
Late summer and early fall bring the warmest days, as the fog thins and the ocean breeze eases. Winter storms come in from the southwest with most of the year's rain and the biggest surf. Their high tides push water into the lagoon and against the bluffs at the edge of the mesa.
Tips for visiting Bolinas
Keep clear of the bluff at the town beach
Marin County has posted an advisory for parts of Bolinas Beach because of an unstable bluff face and on-site contamination. Stay away from the bluff base and follow the posted signs.
Take the Marin Transit bus
A Marin Transit bus runs from Sausalito over Mt. Tam and through Stinson Beach to downtown Bolinas, on weekdays and weekends.
Time lagoon and reef walks to the tide
NOAA publishes tide predictions for a station in Bolinas Lagoon. Plan lagoon and reef walks around low tide, when more mudflat and reef are exposed.
Bring binoculars for the lagoon
Bolinas Lagoon is an 1,100-acre tidal estuary, a wetland of international importance under the Ramsar treaty, and an Audubon Important Bird Area. Binoculars help with shorebirds on the far mudflats.
Pack a windbreaker even on sunny days
The open mesa catches the full northwest wind, and fog can roll back in within minutes on summer afternoons.
Bolinas through the seasons
- Spring (March–May)
- Spring is the windiest season on the mesa, with strong northwest breezes. Rain tapers off and the fog builds again by May.
- Summer (June–August)
- Summer is fog season. Mornings are usually gray and cool, and a jacket is needed by late afternoon even when the sun breaks through.
- Fall (September–October)
- September brings the warmest weeks of the year, with less fog than midsummer and lighter wind for beach days.
- Winter (November–February)
- Winter brings the most rain and the largest surf. High tides on top of storm swell push into the lagoon and against the bluffs, so check tide times before walking the shore.
Activities and the weather that matters
- Surfing: Small to mid-size swell with light morning wind is ideal. Afternoon northwest wind and big winter storm surf make it rough.
- Tidepooling and beachcombing: Go at low tide when the surf is calm. Stay away from the bluff base after rain, when slides are more likely.
- Birding on the lagoon: Calm, overcast mornings are fine for birds. Strong afternoon wind makes scopes shake and birds hunker down.
