San Onofre

San Onofre is an SW-facing reef break in Orange County & San Clemente, California, United States. It picks up swell from SSE to S and S to SW, and land, islands, reefs or shallow banks block about 63% of the directions it faces. Offshore wind here blows from the NE: light winds or NE breezes usually mean the cleanest surf, while SW onshores chop it up.

Rare slot: a Channel Islands gap lets in swell from 257.2° (WSW) and nothing either side. It only lines up when a storm sits in that exact direction, more than 100 km out. How slot swells work

Rare slot: the San Pedro Channel lets in swell from 282.5° (WNW) and nothing either side. It only lines up when a storm sits in that exact direction, more than 240 km out. How slot swells work
