About Trestles (San Onofre)
Trestles (San Onofre) is Lower and Upper Trestles, the world-class cobblestone peaks at San Mateo Creek in San Onofre State Beach in San Diego County. Like most Southern California breaks, its water quality is driven mostly by runoff: after rain, storm drains, creeks and river mouths flush bacteria into the surf zone, and county health officers advise staying out of the ocean for at least 72 hours. During dry weather, water near creek mouths, piers and enclosed beaches still tends to grade worse than open coastline. County agencies sample weekly (more often in summer) and post advisories when bacteria exceed state standards, or close beaches after sewage spills. Ocean temperatures here typically run from the high 50s°F in spring upwelling to the low-to-mid 70s°F in late summer, so check the live reading above before choosing your rubber.
