San Diego started today on the gray and chilly side, with clouds and temperatures hovering near 70°F around Lindbergh Field. The marine layer is expected to peel back by midmorning, letting highs climb to about 79°F this afternoon. Light south winds of 5–10 mph will drift in with the sunshine, and tonight should stay comfortable with lows near 67°F. Expect the usual coastal routine: fog early and sun by midday, with a repeat tomorrow. The real twist arrives Sunday evening, when surf conditions could throw a wrench into those beach plans.

High Surf And Rip Currents

According to the National Weather Service San Diego, a High Surf Advisory is in effect from tomorrow at 5:00 PM through next Tuesday at 11:00 PM. Forecasters are calling for large breaking waves of 4–7 feet, with sets up to 8 feet on south and southwest facing beaches. The advisory puts it bluntly: Inexperienced swimmers should remain out of the water due to dangerous surf conditions.

Beach And Boardwalk Impacts

Evening high tides combined with the incoming south swell could push seawater into low-lying boardwalks and beach parking lots during peak tides, and some localized beach erosion is on the table. 

Afternoons, Winds, And The Week Ahead

Outside of the surf, the pattern looks about as classic San Diego as it gets. Mostly sunny afternoons through midweek should bring highs in the upper 70s to low 80s with light winds. Night and morning low clouds will hug the immediate coast, then clear out by midmorning. The chance of mountain thunderstorms stays low this weekend. A modest warming trend is possible by Wednesday and Thursday, while surf and rip currents remain the big concern along the shoreline.

What To Do

To stay on the safe side, stick to guarded beaches, follow lifeguard flags, and avoid entering the water when rip currents are active. If you are planning an evening beach outing during the advisory window, park on higher ground and check in with local lifeguard reports and the National Weather Service before you head for the water.
