Before you swim
Surf is running 4.1 ft today, which makes shorebreak and currents stronger than usual.
At 61°F the water is cold enough that unprotected swimmers risk cold-water shock.
Swim near a staffed lifeguard tower, and check the National Weather Service surf-zone forecast for the official rip-current outlook — we report conditions, we don't forecast rip currents.
