What to Wear in San Francisco in October
October in San Francisco brings what locals call 'second summer' — the clearest, warmest weather of the year with highs averaging 68°F and lows near 55°F, a dramatic improvement over the foggy June–September period. Light-to-medium layers are key, as the Bay Area's microclimates mean a 68°F afternoon in the Mission District can feel like a different world than a 58°F windy afternoon near the Golden Gate. Rain is minimal with only 5 wet days.

Based on typical October conditions in San Francisco. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
October in San Francisco often delivers some of the year's most pleasant weather, frequently referred to as "Indian Summer." Unlike the notoriously foggy summer months, October typically sees more sunshine and milder temperatures, ranging from comfortable highs in the mid-60s to low 70s Fahrenheit (18-22°C) during the day. However, evenings cool down considerably, dipping into the mid-50s (12-14°C), and the city's famous microclimates mean conditions can shift rapidly from sunny warmth to cool, breezy shade, especially near the waterfront or when the fog rolls in unexpectedly. While precipitation likelihood increases slightly as the rainy season approaches, heavy downpours are uncommon; you're more likely to encounter light drizzles than sustained rain. The key to dressing for San Francisco in October is masterful layering. Begin with versatile base layers like long-sleeved tees or light blouses. Add a cozy cardigan or a light sweater, and top it off with a medium-weight jacket—a stylish denim, leather, or a water-resistant trench works perfectly for adapting to the day's varying conditions. Comfortable, sturdy walking shoes are non-negotiable for navigating the city's iconic hills, and a scarf can provide essential warmth against unexpected breezes while adding a touch of fashion. Always carry sunglasses for the bright sunshine, but be prepared to shed or add layers throughout your adventures.
