California – Low clouds drift across the coast this morning, and the air feels heavier than usual for late December. Sidewalks stay dry for now, but umbrellas won’t stay folded for long. A developing Pacific system is lining up to bring San Diego its wettest stretch in weeks as the calendar flips to 2026.
According to the National Weather Service in San Diego, rain chances increase late today and continue building through Wednesday night. Showers become likely on Wednesday, with widespread rain expected by New Year’s Day 2026. Confidence is high that wet conditions will persist into Thursday, affecting travel and outdoor plans.
Across San Diego County, highs today climb into the mid-70s before clouds thicken. By Wednesday, temperatures cool into the upper 60s as showers spread inland. Rain intensifies Wednesday night, with periods of steady rainfall expected early New Year’s Day. While flooding is not guaranteed, ponding on roads is possible during heavier bursts.
In San Diego, commuters should prepare for slick pavement on I-5, I-8, and I-15. Visibility may drop at times, especially near the coast and higher terrain. Plan extra time if traveling for New Year’s events, and slow down on wet roads where oil buildup can make surfaces especially slippery.
Rain chances linger into Friday and Saturday, keeping conditions unsettled into the first weekend of 2026. Skies remain mostly cloudy, and additional light showers are possible, especially during the mornings.
Residents should secure outdoor decorations, keep rain gear nearby, and check drains near homes for debris. More updates or advisories may be issued if rainfall trends increase. Heading out for New Year’s celebrations or traveling soon? Tell us how conditions look in your neighborhood.
