From 11 p.m. Monday to 11:00 p.m. Tuesday, a Beach Hazard Statement issued by the National Weather Service will be in effect.

During this time, the NWS explained that the risk of huge shore breaks will increase, as well as wave run-up and rip currents. These can happen late Monday evening until the late evening of the following day.

“After a fairly quiet summer in terms of swell, the first larger northwest swell of the season will arrive tonight,” part of the Beach Hazard Statement read. “Expect an increased risk of moderate to large breaking waves and stronger rip currents.”

As compared to the common waves experienced in local beaches, the rise in winds behind cold fronts mixed with the buildings swell can trigger the waves to shoot afar, officials said.

“This hazard is primarily for west to northwest facing beaches,” officials warned.

According to the NWS, the northwest swell is predicted to eventually lie low on Wednesday.

Locals are told by officials to avoid fishing from jetties or rocks while the order is in effect. Those who want to walk by the beach are also advised not to turn their back to the waves.

Added to these, officials warned of dangerous surf zones because of bigger breaking waves and tough rip water. Those who wanted to surf must be more cautious.

Staying out of the water is also advised for dangerous swimming conditions to be prevented, they said, as reported by KRON4.

San Francisco Chronicle, meanwhile, reported that dangerous conditions could emerge quickly in areas like Ocean Beach in San Francisco, Marina State Beach, and Montara State Beach.
