San Diego, CA – A soft marine haze drifts along the coast this morning, fading as the sun lifts over the city’s skyline. Temperatures hover near 59°F before climbing into the upper 70s by midday — the kind of calm, golden warmth that defines late-October in Southern California.
According to the National Weather Service, San Diego will see mostly sunny skies through Saturday, with highs reaching 77°F to 79°F inland and light sea breezes through the afternoon. Patchy fog will return each night, especially along I-5, La Jolla, and the harbor areas. Drivers heading out early should expect reduced visibility near the coast before midmorning clearing.
Friday and Saturday will bring nearly identical weather: mild days, light winds, and cool nights around 59°F. Sunday stays pleasant but begins a slow transition toward a cooler marine pattern. Meteorologists say onshore flow will strengthen early next week, dropping highs into the low 70s by Tuesday with thicker morning fog and potential drizzle near the beaches.
While San Diego enjoys this final stretch of fall warmth, long-range models suggest a November shift — cooler Pacific air and possibly the region’s first measurable rain later in the month. Inland mountains and northern parts of the state could even see the season’s first snow chances by mid-November.
For now, Halloween weekend offers calm, clear evenings for trick-or-treaters and coastal sunsets — a brief pause before California’s next seasonal change rolls in.
