SAN DIEGO, CA – Early risers across coastal San Diego will wake to a soft blanket of fog Friday morning, muting the sunrise and cooling the air. By midmorning, the haze will lift, revealing another streak of bright, steady warmth as Southern California eases toward the final week of October.
According to the National Weather Service in San Diego, patchy fog will remain the main weather feature through the weekend, especially near the beaches and coastal valleys. Highs will reach the mid-70s each afternoon, with Friday topping near 76°F and Saturday closer to 73°F. Winds stay light, mostly under 10 mph, creating stable, comfortable days ideal for outdoor plans.
Fog will be most noticeable along I-5, the 805, and through the La Jolla and Del Mar corridors before late morning. Drivers should watch for reduced visibility and allow extra travel time through coastal routes. Once skies clear, sunshine dominates with calm, dry air continuing into Sunday.
By early next week, mild warmth builds again. Monday and Tuesday are expected to hit the upper 70s to near 80°F, holding dry with mostly clear skies. It’s a classic San Diego late-October stretch — steady temperatures, crisp mornings, and golden afternoons that feel more like early fall than the edge of winter.
Looking ahead to Halloween week, models hint at slightly cooler air returning midweek, with light coastal fog possible for trick-or-treaters. While much of the U.S. braces for frost, San Diego holds onto its calm, coastal rhythm — a gentle reminder that “fall” here means sunsets, not snowflakes.
