Normally you are not supposed to surf within 72 hours of rainfall hitting southern California. Runoff from storm drains, streets and everything else washes into the ocean. But the Silver Strand State Beach in Coronado, just up the beach from where we live in Imperial Beach, is almost free of development. There is no runoff to speak of, since the parking lots drain east toward the bay. Unless the sewage plume from the Tijuana River travels north, the Silver Strand can be a good bet.
Most of the time the Strand is a horrible place to surf. The waves are almost always closed out. I worked as a lifeguard there for eight years and rarely saw it good. But with the rain and storm swell that hit Southern California yesterday, the waves at the Strand were a little broken up this morning and the groms scored some fun corners that were helped out by an offshore wind.
