San Diego is starting Sunday under cloudy skies, with a mild afternoon ahead and a high around 77. The gray pattern will linger into the start of the week, bringing a chance of patchy drizzle before a warmer, sunnier stretch takes over by the weekend.

Clouds And Drizzle Lead The Week

Clouds will return Sunday night. Patchy drizzle is possible early Monday, and the day may remain cool.

Another round of patchy drizzle is possible late Monday night and before 11 a.m. Tuesday. Tuesday should then reach a high near 77.

Warm-Up Arrives By Wednesday

The forecast turns noticeably warmer Wednesday, when San Diego could reach 78 degrees. Thursday climbs to about 81, followed by highs near 75 Friday and 77 Saturday.

The outlook marks a substantive update from Hoodline’s earlier forecast, with the latest guidance adding a cooler, breezier start and a clearer weekend warm-up. Even with the morning clouds and drizzle, no weather alerts are currently posted, and the National Weather Service expects no hazardous marine conditions through Thursday, according to its San Diego forecast discussion.
