HALF MOON BAY, Calif.— An Orange County surfer who wiped out on a treacherous wave at Mavericks has been in a medically induced coma since Saturday’s accident.

A spokesman at Stanford Medical Center says 30-year-old Jacob Trette is listed in critical condition after nearly drowning at the famed surf spot north of Half Moon Bay.

The San Francisco Chronicle reports that Trette and more than a dozen others were riding 15- to 18-foot waves Saturday morning when a larger one surprised them.

Authorities say Trette was found face down and not breathing in the water and pulled out by a photographer on a personal watercraft.

The Chronicle reports that Trette, an accomplished surfer from San Clemente, had only attempted the waves at Mavericks once before.
