Big Jetty is a jetty break in San Diego, CA. Big Jetty produces heavy, wedging waves that bounce off the south jetty wall of the Mission Bay channel entrance. The signature wave is a thick, bowling right that jacks up fast and throws a short but intense barrel. Lefts peel away from the jetty and are more workable but less exciting. The wave gets serious above 4 ft—the backwash off the rocks creates unpredictable sections and the currents intensify dramatically. On big swells, the channel current rips hard and can sweep you into the bay entrance. The sandbar configuration changes with season but the jetty provides a consistent reference point for the peak. Forecasts are updated every 3 hours using ML-corrected NOAA models with live buoy data from CDIP, NDBC, and IOOS stations.
