Based on typical August conditions in San Francisco. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
San Francisco in August is famously counter-intuitive. While much of the Northern Hemisphere swelters, the "City by the Bay" often experiences its coolest and foggiest month. Expect average high temperatures to hover around 65°F (18°C) and lows dipping into the low 50s°F (10-12°C). Persistent morning and evening fog, known affectionately as Karl the Fog, is a hallmark of summer here, often accompanied by brisk winds that make it feel significantly colder, particularly near the coast and at higher elevations. Rain is exceedingly rare, so you won't need to worry about umbrellas. For practical advice, layering is paramount. A light t-shirt or tank top serves as a good base. Over this, pack a cozy sweater, fleece, or a stylish cardigan. A windproof and water-resistant jacket is essential – think trench coat, denim jacket, or a lightweight puffer – to combat the notorious San Francisco winds and any lingering dampness from the fog. Even on seemingly sunny afternoons, the temperature can drop quickly, making a substantial outer layer indispensable. Don't forget long pants or jeans; shorts are rarely appropriate unless you're staying exclusively in warmer inland areas like the Mission District on a rare sunny day. Comfortable closed-toe shoes are also a must for navigating the city's famous hills.
