San Onofre State Beach Surf Forecast
BREAK TYPE
Mellow longboard waves at one of California's most iconic surf spots.
GOOD FOR
The wave rolls over a rounded cobblestone reef that sits roughly 200 to 400 yards offshore, unspooling soft A-frame peaks that fan into long, forgiving shoulders. Size stays mellow on most swells, with rides that can stretch 50 meters or more when it lines up. Beginners find gentle inside reforms, while loggers work the outer peaks on classic single fins and mid-lengths.

WHEN IT WORKS
San O breaks on almost any swell direction, which keeps it working through the calendar, but summer south and southwest pulses light up the outer reef most reliably. Fall keeps the water warm and the lineup a touch thinner. Mornings usually deliver light east offshores before the afternoon onshore fills in, and a medium tide works best over the cobblestones.

WHAT TO KNOW
Real dangers stay low, with no heavy rips and a padded outer reef. The bigger issues are people and rocks. Cobblestones surface at lower tides and can shred bare feet, so booties earn their keep. Weekends and holidays draw thick crowds, with longtime regulars stacked on the main peaks; wait a turn, avoid the drop-in, and the family-friendly vibe San O is known for stays intact.
GETTING THERE
Exit I-5 at Basilone Road and head south. Old Man's is the rare California spot where you drive straight onto the sand, with a $15 day-use fee or state park pass. Trails sits south of the power plant, reached by six short bluff paths dropping about 160 feet to the shore. Trestles takes a 1 to 2 mile walk from Cristianitos Road or the San Mateo Campground nature trail.
