Big Jetty fires on a clean west or WNW swell in the 4-8 ft range with 14+ second period and light offshore winds. The wedge effect is most pronounced on a dropping tide from high to mid—the backwash off the rocks amplifies the wave face and creates the bowling takeoff. Winter is prime season. The best sessions happen on early morning glass with a medium-period WNW swell wrapping into the 265-degree exposure. Avoid it on big south swells, which push water straight into the jetty and create chaotic, unsurfable conditions.
