Purisima Creek Redwoods Weather

Park • San Francisco Bay Area

Purisima Creek Redwoods is Midpeninsula Regional Open Space District's 5,412-acre preserve on the ocean side of the Santa Cruz Mountains, overlooking Half Moon Bay. Trails drop from trailheads on Skyline Boulevard into Purisima Creek Canyon and come out at a small creekside trailhead on the coast side. The canyon's second-growth redwood forest was logged in the late 1800s and early 1900s. Where Edgewood and Woodside sit on the sunny bay slope, this preserve faces the Pacific and takes its fog.

The preserve faces the open ocean, and that decides most days here. In summer, the sea breeze carries the marine layer across the Half Moon Bay coastal terrace and up the creek canyons. That layer is the cool, damp ocean air that holds the fog. The redwood bottoms are often gray, damp, and still while Woodside and Edgewood, just over the ridge, are in full sun. Fog moving through the trees condenses on needles and drips to the ground, keeping the canyon cool and moist through the dry season.

Forecast updated November 15, 2026 at 4:00 AM PST. Climate figures come from NOAA 1991-2020 normals. Hourly patterns come from NOAA's HRRR hourly analysis from September 2014 to April 2026.

What shapes Purisima Creek Redwoods' weather

Purisima Creek Redwoods spans a big climb, from the creekside trailhead near the coast up to Skyline Boulevard on the crest. When the marine layer of cool, foggy ocean air is shallow, the ridgetop parking areas on Highway 35 can sit above a sea of fog. The canyon below stays socked in. When it is deep, the ridgetop is inside the cloud itself, wet, windy, and cold.

Winter storms hit the Purisima Creek slope hard. Pacific storms are forced up the west face of the Santa Cruz Mountains, so this slope wrings out more rain than the bay side of the ridge. Creeks run high, dirt trails turn to mud, and the open space district may close trails to bikes and horses when they are wet.

Tips for visiting Purisima Creek Redwoods

  • Carry all your water

    There's no drinking water in the preserve. The district suggests two quarts per person for every two hours of hiking.

  • Pack layers for the climb back

    Temperatures shift between the shaded canyon and the ridge, so dress in layers you can add for the cooler, damper stretches.

  • The creek trailhead is tiny

    The Purisima Creek Road lot has seven spaces plus one accessible space, and No Parking zones are strictly enforced. The North Ridge lot on Highway 35 is much larger.

  • Check closures after storms

    Trail closures can change day to day after rain, and high water can make creek crossings hazardous.

  • No dogs, and spotty cell service

    Dogs aren't allowed (service dogs are accommodated), and cell coverage is sporadic, so download a map first.

Purisima Creek Redwoods through the seasons

Spring (March–May)
The creek still runs strong after the rains while the trails dry out. Fog starts returning to the coast late in the season.
Summer (June–August)
Summer is fog season. The canyon stays cool and often drips even during inland heat, and the ridgetop trailheads may be above the fog or inside it.
Fall (September–October)
Fall is often the clearest stretch, with the best chance of open views from Harkins Ridge, Whittemore Gulch, and Soda Gulch down to Half Moon Bay.
Winter (November–February)
Winter is the wettest season. High water can make creek crossings hazardous, and the district sometimes closes trails or whole preserves during storms.

Activities and the weather that matters

  • Hiking the Purisima Creek Trail: This old logging road follows the creek past redwood groves and big stumps. It is a good summer choice when inland trails are hot, and it turns muddy after winter storms.
  • Redwood Trail stroll: This flat, quarter-mile accessible trail starts off Skyline Boulevard. Ridge fog and drizzle are common in summer, so bring a jacket.
  • Mountain biking: The steep Whittemore Gulch Trail is popular with riders but may close to bikes in wet conditions. Ride it dry.
  • Coast views from the ridges: Harkins Ridge and the northern trails look out over Half Moon Bay, but only on days when the marine layer is low or gone.
