SAN DIEGO, Calif. – Fall sunshine continues to shine on Southern California, with a warm, dry weekend expected across the San Diego region before patchy coastal fog makes a brief return early next week. Temperatures will climb into the upper 70s by Saturday and Sunday, offering ideal weather for outdoor plans, beach trips, and fall festivals.
According to the National Weather Service in San Diego, light winds and clear skies will dominate through Sunday. Highs along the coast will reach 77°F to 78°F, while inland valleys stay near 80°F under mostly sunny conditions. Those driving along I-5 and I-8 should expect excellent visibility and smooth travel through the weekend.
By Monday, a shallow marine layer develops, pushing patchy fog into the coastal areas and low valleys before sunrise. Commuters should use caution on Highway 163 and Pacific Coast Highway, where reduced visibility may create slowdowns through mid-morning. Once the fog lifts, skies will clear again with comfortable highs in the mid-70s.
Through midweek, San Diego remains in a steady fall pattern — sunny, mild, and dry. These calm days are perfect for pumpkin patch visits, beach walks, and early Halloween decorating before a potential cooling trend later next week.
Five-Day Outlook for San Diego, California:
Friday: Sunny, high 75°F.
Saturday: Mostly sunny, high 78°F.
Sunday: Mostly sunny, high 77°F.
