California – Waves slam against rocky shorelines this morning as whitewater surges higher than usual along the San Francisco coast. The air feels damp and cool, and the ocean looks restless. Conditions are already drawing attention as a High Surf Weather Alert remains in effect.
According to the National Weather Service, a High Surf Advisory continues through Thursday evening for the San Francisco coastline. Large, powerful northwest swells are expected to create dangerous conditions near beaches, jetties, and coastal trails. Breaking waves and strong currents may pull debris onto normally dry areas.
Across San Francisco, morning temperatures hover in the lower 50s, with highs reaching the upper 50s this afternoon. Skies trend brighter by midday, but the ocean threat persists even as clouds thin. Gusty coastal breezes develop Wednesday, adding to choppy marine conditions and reduced stability along exposed cliffs.
Drivers and pedestrians near Ocean Beach, the Great Highway, and coastal viewpoints should stay alert. Wet pavement and blowing spray can reduce visibility at times. Parents dropping children at school near coastal routes are urged to slow down and allow extra time.
Into Thursday, sunshine becomes more dominant while temperatures cool slightly at night, dipping into the low 40s. The Winter pattern stays dry inland, but the ocean remains hazardous. Officials warn against turning your back to the surf, as sneaker waves are possible.
By Friday and into the weekend, surf gradually lowers, and calmer conditions return. Afternoon temperatures remain seasonable, and daylight continues its steady January increase, offering longer evenings by month’s end.
