Reef break in south Oceanside known for hollow waves.
Sand bottom peaks shift with the season, breaking over bars that set up along a narrow south Oceanside stretch. On a clean chest to head high swell the takeoffs are steep and short, with quick shoulders that reward a fast bottom turn. It comes alive on a filling mid tide when the inside has water on it. Intermediates handle it easily, and it suits a shortboard or fish.

Exposure is wide open to south and southwest swells through summer, with west and northwest angles filling in during the cooler months, so something usually breaks year round. Late spring through early fall tends to deliver the most consistent shape. Light morning offshores clean it up before the afternoon westerly blows it flat, and a filling mid tide is the sweet spot.
The main concern is the boulder riprap lining the back of the beach, which swallows the sand at high tide and leaves nowhere dry to sit out a set. Buena Vista Lagoon drains just to the south and the San Luis Rey River sits to the north, so water quality tanks for a few days after heavy rain. Localism is mild, though the peak is small and the lineup crowds quickly on a clean swell.
A solid wooden staircase at the western end of Cassidy Street drops straight to the sand, about a thirty second walk from the curb. Street parking sits along Pacific Street and the residential blocks just inland, and it fills fast on weekends. There are no restrooms, showers, or lifeguard towers on site. Surfers also walk down from South Oceanside Beach a few blocks north.
