Oceanside Harbor Current Conditions Summary
Oceanside Harbor in Oceanside, CA is a jetty break. Current conditions: 1.3 ft waves, wnw 8–13 mph (cross-shore), falling → low. Small for this break but conditions look fun — 1.3 ft with manageable wind. **Oceanside Harbor** (North & South Jetties) produces consistent jetty-formed rights rated 7/10. The south jetty creates a long, walling right that peels along the rocks on northwest swells. On solid days it can run 100+ yards. The wave jacks up fast off the jetty boulders and throws a steep, hollow takeoff. Sit tight to the rocks but not so close you risk getting pushed into them—about 15-20 feet off the jetty is the sweet spot. Left slides are shorter but can barrel on bigger days. The harbor channel creates a consistent rip that acts as a paddle-out conveyor belt—use it. Forecasts are updated every 3 hours using ML-corrected NOAA models with live buoy data from CDIP, NDBC, and IOOS stations.

Oceanside Harbor is a working harbor, so the surf crowd here is a mix of locals, Camp Pendleton Marines, and traveling surfers checking the jetty. Weekday mornings are manageable with maybe 10-15 surfers out. Weekend mornings can see 30+ in the water, especially on clean winter swells. Dawn patrol is essential on good days. The south jetty side draws the most crowd—if it's packed, check the north jetty or walk south toward the harbor mouth for less competition.
