San Diego, CA – A soft, hazy layer drapes the coastline this morning, muting the sunrise and dimming headlights along I-5 and Highway 163. The National Weather Service is urging caution as patchy dense fog reduces visibility in low-lying areas and valleys. Drivers heading toward downtown or Mission Valley should allow extra time and keep low beams on through early morning hours.
As the fog burns away, sunshine quickly reclaims the sky, signaling a mild December stretch across the region. Today’s high will reach near 68°F, climbing steadily through the weekend as offshore flow strengthens. By Monday and Tuesday, temperatures rebound into the mid-70s, giving San Diego a taste of early winter warmth while much of the country braces for snow and ice.
Meteorologists expect clear, calm conditions through midweek with no major precipitation threats, though overnight fog could redevelop Sunday and Monday in coastal zones. Winds will remain light, occasionally gusting up to 20 mph inland, helping disperse haze by afternoon.
If you’re planning coastal travel, expect morning slowdowns from La Jolla to Chula Vista, but otherwise, it’s a bright stretch for outdoor plans and early holiday prep.
