Lower Trestles is one of the best waves in the world — a cobblestone point break that produces both rights and lefts off a perfectly defined peak. Selected as the 2028 LA Olympics surfing venue and longtime WSL Championship Tour stop. The wave is rippable and consistent but the crowd and competition-level lineup make it effectively advanced. The 15-minute walk from the parking lot is the only thing keeping numbers in check.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Trestles is 2-3+ft with a 5.6s swell period. Wind is SSE at 4mph. Conditions are rated Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Trestles is 2-3+ft, produced by a 2.5ft W wind swell swell at 6s, a 2.1ft SSW secondary swell at 11s, a 1.3ft SSW tertiary swell at 16s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.
Based on the current 5-day forecast, the best window to surf Trestles is Sunday from 11 AM to 2 PM with 8ft waves, a 13.8s swell period, and conditions rated Good. Check the hourly forecast for updates as conditions can shift.
Trestles works best with a SSW swell and ENE winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.
Tide plays a big role at Trestles. Mid tide works for most beach breaks, while reef and point breaks often prefer higher or lower stages. Use the tide chart above to line up your session with the swell peak.

Common hazards at Trestles include extreme crowds, high-performance lineup, cobblestone bottom, long walk in. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Trestles forecast uses NOAA GFS and other weather models combined with spot-specific bathymetry to calculate breaking wave heights. Short-range (1-3 day) forecasts are most reliable; extended forecasts show general trends. We also verify our offshore swell predictions against NOAA buoy measurements daily — see our accuracy page for those swell-verification metrics (buoys measure open-water swell, not breaking surf size).
