After a below-normal Sunday, Monday begins a warmup, with the city headed for a sunny Labor Day and a high near 77. The bigger caution is at the Pacific shoreline, where dangerous surf—not the afternoon forecast—is the day’s main weather story.

Sunny Labor Day, Breezier By Afternoon

Skies should stay clear through the day, with temperatures reaching the mid-70s and no rain expected.

Tuesday could see light rain showers, although the forecast had trended drier, according to Hoodline’s earlier forecast. The warming trend is expected to peak Wednesday and Thursday.

Beach Hazards Continue Through Monday Evening

A Beach Hazards Statement remains in effect through Monday evening for Pacific Coast beaches, with sneaker waves, strong rip currents and breaking waves around 10 feet possible. The National Weather Service advises staying out of the water and away from jetties, piers, rocks and other shoreline infrastructure. According to the National Oceanic and Atmospheric Administration, rip currents account for over 80% of rescues performed by surf beach lifeguards, underscoring the broader danger behind local warnings.

Midweek Heat Gives Way To Cooler Weekend

Thursday turns sunny again with a high near 77, but the forecast cools late in the week and into the weekend. Sunday’s forecast remains unspecified, while rain chances remain unspecified.

For city plans, Monday looks ideal for outdoor time away from the surf: bring a light layer for the morning, expect a warmer afternoon and keep extra distance from the ocean. The warming trend is expected to peak Wednesday and Thursday, so anyone sensitive to heat may want to plan errands and outdoor activities accordingly.
