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.
August is San Francisco's famous cold-summer paradox — the rest of California bakes while the Bay Area fog machine runs at full intensity. Highs average only 68°F and frequently don't register at Fisherman's Wharf and the Embarcadero, where full Bay wind and fog keep temperatures in the 55–60°F range through the afternoon. Only about 1 rainy day means no rain gear needed, but a real jacket is essential every single day regardless of what the inland forecast says. San Francisco's eclectic, tech-casual-meets-Mission-hipster aesthetic makes perfect sense with its weather: layers are not a style choice but a practical requirement. A mid-weight jacket over a lightweight base, with the option to add a scarf for the waterfront, covers the full August range. The steep hill terrain throughout the city — Castro, Noe Valley, Lombard Street — makes flat-soled or low-heeled shoes essential for any meaningful walking. The Mission District is one of the few reliable sun traps, warming up to 65–70°F when the Sunset is still fogged in.
Curated Looks
Business Casual
Mauve Happy Hour
At 65–74°F the mauve tie-front cropped linen shirt earns its place over ivory wide-leg linen trousers. Ivory pointed-toe mules and aviator sunglasses make the commute feel like an editorial moment.
Casual
Bright, Blue, and Breezy
Embrace the 65–74°F sunny weather with a breathable linen shirt, classy bermuda shorts, and espadrilles. Pair it with a class bucket bag for that summer ready look.
Chic
White Shirt Wide-Leg
A white oversized button-down with ivory wide-leg linen trousers and a brown woven belt is the warm-clear uniform for someone who doesn't overthink it. Black mule heels are the one decisive choice.
Sporty
Biker Shorts Graphic Tee
A black graphic tee over biker shorts with mule heels is the warm-day sporty look that works from coffee to casual. The olive baseball cap adds a directional touch.
Formal
Ivory and Pleated Maxi
An ivory silk-look blouse tucked into a black pleated maxi skirt is the warm-clear formal look with evening flexibility. Espadrilles and a black mini bag make it daytime without losing the occasion feel.
Cute
Floral Skirt and Mules
A floral pleated midi skirt with a white fitted tank and black mules reads warm-day dressed-up without veering formal. A crochet bucket hat shifts the mood back to weekend.

Frequently Asked Questions
What should I wear in San Francisco in August?+
San Francisco in August averages 68°F with frequent fog that keeps the waterfront in the 55–60°F range. A mid-weight jacket is the most important item you'll pack — August is the city's coldest month despite being summer. Layers underneath the jacket, flat shoes for steep hills, and an extra scarf for the Embarcadero wind complete the August kit.
Why is San Francisco cold in August?+
San Francisco's August cold is caused by the marine layer (Karl the Fog) that intensifies in summer when California's Central Valley heat creates a pressure difference that pulls cool Pacific air over the Bay Area. The fog keeps the coast and bay areas in the 55–60°F range throughout the day. The Mission District and Dolores Park are usually warmer sun traps, 10–15°F above the waterfront.
Is August a good time to visit San Francisco?+
August in San Francisco is great if you pack for it — the city is fully active, culturally rich, and beautiful even under fog. The key is bringing a mid-weight jacket and not expecting beach weather. If you want California sunshine in August, fly to San Diego instead. But if you want world-class food, culture, and the Golden Gate Bridge, pack your layers and San Francisco in August is excellent.
What shoes should I wear in San Francisco in August?+
Flat-soled or low-heeled shoes are essential for San Francisco in August. The city's steep hills throughout the Castro, Noe Valley, Pacific Heights, and North Beach neighborhoods make heeled walking genuinely difficult — flat ankle boots are the San Francisco standard for good reason. The Embarcadero and Fisherman's Wharf waterfront areas are flat but wind-exposed.
What should I pack for San Francisco in August?+
Pack layers for San Francisco's August — specifically, a mid-weight jacket, a light cardigan or pullover for layering underneath, and a scarf for waterfront wind. Flat shoes for steep hill navigation, and breathable base layers that work at 55°F foggy morning and 68°F afternoon are the practical core. Leave the sundresses and tank tops for the inland days; San Francisco in August rewards layers over everything.
