SAN FRANCISCO, Calif. – Golden sunlight spills across the Bay early this morning, glinting off calm water and quiet piers. The city wakes under clear skies and calm air — the kind of gentle start that defines California’s best autumn mornings. But while the next few days stay comfortably mild, changes are on the horizon as a Pacific system edges toward the coast by Friday.
According to the National Weather Service in Monterey, today brings bright skies and highs near 76°F across downtown San Francisco and the Peninsula. Light westerly winds pick up slightly this afternoon, making for an ideal day to get outside before the week turns breezier and cloudier. A Beach Hazards Statement remains in effect through early Thursday for coastal Marin and San Mateo counties, with sneaker waves and strong rip currents possible. Beachgoers are urged to stay off rocks and jetties and never turn their back to the surf.
By Wednesday and Thursday, inland warming peaks with highs reaching the upper 80s in warmer valleys while the city holds near 68°F. Winds remain light but will shift southwest as the marine layer rebuilds Thursday night. By Friday, increasing clouds signal the arrival of the next system, bringing a chance of light rain into early Saturday.
The weekend looks cooler and partly damp — highs dropping into the upper 60s with lingering clouds. After a week of gentle fall warmth, the Bay Area appears set for its first taste of early-season transition weather — a soft, welcome preview of California’s cooler months ahead.
