San Diego woke up to clear skies and a brisk start around 45°F at San Diego International Airport (KSAN) this morning, the kind of chill that makes you grab a jacket on your way out. By afternoon, though, it will feel a lot more like borrowed spring, with mostly sunny skies and a high near 68°F today. Temperatures are expected to climb through the weekend, heading into the mid‑70s by Monday.
Afternoon And Weekend Outlook
This afternoon stays mostly sunny with a light north breeze around 0 to 10 mph and a mild high near 68°F. Tonight turns mostly cloudy, and temperatures dip to a low near 49°F. Sunday should be a little brighter and a bit warmer, topping out near 71°F, and Monday looks to be the warmest day, with highs near 76°F pushing much of the county into the mid‑70s. The National Weather Service San Diego notes that a strengthening ridge will keep weather systems to the north and leave the region dry through midweek.
Fog, Frost And Morning Commutes
Overnight, weak offshore flow and cooling could allow wind-sheltered inland pockets to slip down near freezing. That setup can produce patchy frost and localized fog, conditions already reported at Ramona and possible along parts of the I‑15 corridor. Early commuters should be ready for reduced visibility and a few slick spots before sunrise, even without any active watches or warnings in effect for the county this morning.
What To Pack And When To Head Out
Plan for a split wardrobe: sunglasses and shorts by midday, a sweater or light jacket for that pre-dawn run. Offshore winds remain light, and the marine forecast points to no hazards through Thursday. Even so, rip currents and elevated surf have lingered this month, so beachgoers should still pay attention to local conditions. It is a good idea to secure loose patio items before any gusty afternoon winds decide to return and to double-check beach reports if you are heading to the coast.
