San Diego, CA – The morning air feels still and cool along the coast, a faint gray haze beginning to form over the bay before the sun takes control. The mild rhythm of early December continues in Southern California, with patchy fog at dawn giving way to bright, mid-70° afternoons through Saturday.
The National Weather Service in San Diego calls for mostly clear skies and calm conditions into the weekend. Light fog may briefly develop each morning along Interstate 5 and coastal communities before sunshine dominates by midmorning. Highs will reach 72 to 73°F, a near-perfect setup for outdoor plans, holiday shopping, or decorating under the palms.
While much of the country braces for Arctic cold, San Diego remains in a comfortable stretch — but forecasters note subtle signs of change next week. Models hint at a cooler, cloudier pattern developing by late Monday, possibly introducing light marine drizzle and denser fog near the coast.
For now, drivers should stay alert for reduced visibility during early commutes, especially near coastal valleys and airport approaches. Calm winds and clear evenings will make for ideal outdoor dining or waterfront walks heading into Sunday.
