Surfing in the Bay Area means cold water, frequent fog, strong wind and swells that change sharply with the seasons. It feels very different from surfing in Southern California. In return, local surfers get powerful waves, dramatic scenery and lineups that are often less crowded. The best time to go depends on the spot and on what kind of surfing you want. Beginners look for small, steady waves and light wind, while experienced surfers want bigger swell they can still manage. Big wave riders chase the same winter storms that keep everyone else indoors. Each season brings a different mix of swell, wind and weather.
Fall: The Peak Season
September through November is the best all-around surf season in the Bay Area. The strong northwest wind of summer starts to ease, and the first swells from storms in the North Pacific begin arriving in September and October. Crowds are thinner than in summer, and the weather is often clearer and warmer than during the foggy months. On good days, waves run in the head-high to overhead range, and mornings often bring light or offshore wind.
That combination of steady swell and calm mornings is why many local surfers call fall their favorite season. Ocean Beach in San Francisco, Pacifica and the Half Moon Bay coast all tend to have their most consistent, best-shaped waves at this time of year.
Fall is also when the ocean is at its warmest, though warm is relative. The water usually runs from the mid 50s to the high 50s. Most surfers wear a 4/3 wetsuit, which is 4 millimeters thick on the body and 3 millimeters on the arms and legs. Some add boots and a hood on cold days. The ocean stays cold all year because steady northwest winds push surface water offshore, and colder water rises from below to take its place. That process is called upwelling, and the cold California Current flowing south from Alaska adds to the chill.
Winter: Big Swell Season
Winter, from about November through March, brings the biggest swells of the year. Large storms in the North Pacific send long-period swell, with waves spaced far apart and packed with energy, all the way to the California coast. The same season also brings rain, stormy wind and the hardest conditions of the year. The swells that produce giant waves at Mavericks often make Ocean Beach too big and messy to surf, with long walls of whitewater and no clear path out.
Winter surfing is mostly a matter of timing, and the best days come when a swell is still running but the wind has dropped or turned offshore. That often happens in the morning, or in the calm, clear spell after a storm passes. On those days Ocean Beach, Linda Mar in Pacifica and exposed points along the San Mateo County coast can be excellent. During an active storm, with cold rain and strong onshore wind, most spots are not worth the effort.
Long-period winter swells also bring sneaker waves, which surge far up the beach with little warning. Before you paddle out or walk along the shoreline, spend a few minutes watching the water to see how far the biggest sets reach.
Summer and Spring
Summer is the quietest season for Bay Area surf. Storms in the North Pacific mostly shut down, and the waves that do arrive come from storms far away in the Southern Hemisphere. Those south and southwest swells are usually smaller and less consistent than winter swells. Beginners and intermediate surfers often find summer easier, because the waves are gentler and less powerful.
Wind is the main problem in summer, because the northwest sea breeze builds almost every afternoon and often reaches 20 mph or more. It turns the surface choppy and bumpy. Morning sessions, roughly from dawn to 10 a.m., are usually much cleaner than afternoon ones. Fog is also common in summer, so expect gray skies and cool air on the beach.
Spring is a season of change, and March and April can still bring leftover winter swell, and the weather often improves before the summer fog fully settles in. This is also when the water is coldest, often in the low 50s, because the northwest winds that drive upwelling are at their strongest. May can offer good sessions when a late north swell lines up with a calm morning, and crowds are usually light.
Best Spots for Beginners and Intermediates
Linda Mar, also called Pacifica State Beach, is the Bay Area's best-known spot for learning. The beach slopes gently, the waves are usually small and forgiving, and the cove offers some shelter from the wind. Parking is right next to the sand, and nearby surf shops rent boards and wetsuits. On most days it is the safest place on this stretch of coast to try surfing for the first time.
The Bay Area's most famous break is Ocean Beach, but it is not a place for beginners on most days. The waves are powerful, the currents are strong and the sandbars shift often. Farther north, the beach near Bolinas and Stinson Beach can offer softer waves on smaller days. Beaches around Bodega Bay are more exposed and suit experienced surfers. Because the coast is long and conditions change quickly, local advice about which spot is working on a given swell is worth a lot.
What Are the Biggest Surf Hazards in the Bay Area?
The biggest hazards are rip currents, cold water and large winter swells. Ocean Beach is known for powerful rip currents that can pull even strong swimmers away from shore. The water stays in the 50s for most of the year, so a wetsuit matters for safety as well as comfort. The guide to Bay Area water temperatures by month shows what to expect in each season.
Great white sharks also live along this coast and feed on seals and sea lions, though attacks on surfers are rare. In winter, long-period swells can send sneaker waves far up the beach. Before you paddle out, check the National Weather Service for beach hazard statements and surf forecasts. Once you are on the sand, never turn your back on the ocean.
