The NWS issued a high surf advisory starting at 10 p.m. and extending through 2 p.m. Friday.
“Combined seas building to 8 feet tonight through Thursday and a continuing west-northwest swell Thursday night and Friday around 6 feet at 15 second intervals are likely to generate high surf along exposed west-facing beaches from Cardiff southward,” according to the NWS.
The waves and surf were expected to build tonight to between 5 and 8 feet, with occasional sets that could reach 10 feet, according to NWS forecasters. Those waves could break over jetties, against the bottom of the Ocean Beach Pier and could slam into the base of the cliffs during the morning.
Minor beach erosion and coastal flooding could also be possible, along with very strong rip currents, which forecasters said would be possible from late morning to mid-afternoon each day.
According to the NWS, more high surf is in the forecast for the weekend. Surf heights are expected to increase again Saturday afternoon and Sunday.
