HALF MOON BAY, Calif. (KNTV/NBC) - At least a dozen people were hurt in northern California after they were knocked down by some unexpected surf Saturday.
It happened during a surfing contest in Half Moon Bay, Calif. near San Francisco.
Officials said approximately 13 people sustained significant injuries when they were swept from a seawall, including broken legs and hands.
Officials said the waves were approximately five- to six-feet high by the time they struck, and no one was swept away into the ocean.
The incident ended upstaging the Mavericks Surf Contest which is the world's most lucrative big-wave competition and was scheduled after forecasts called for record-breaking tall waves.
