What to Wear in San Francisco in August

August is 'Fogust' in San Francisco — the namesake month of SF's coldest-summer-in-the-US reputation. NOAA climate data show afternoons at 22°C (72°F), mornings at 14°C / 57°F, barely 1 rain day all month, but near-daily fog. The Pacific wind pushes marine layer over the western half of the city most mornings and often into late afternoon; Mission and Potrero may warm to 25°C / 77°F while Ocean Beach stays at 14°C / 57°F and 20mph wind. Pack as if for SF spring — the season doesn't meaningfully change from May or June. A dark navy coach jacket, a heather grey cardigan, a sheer long-sleeve and a tee, navy relaxed trousers, off-white chunky sneakers. The absurdity of 'August in California' as a cold-weather packing list is exactly why tourists get caught out. Locals find it funny and sell a lot of fleeces to unprepared visitors at Stonestown Uniqlo and the Embarcadero tourist stalls.

The capsule

1. 
   01

   Dark navy coach jacket

   SF August is not materially warmer than SF June. A wind-resistant navy coach layer reads Bay-Area-skater-tech and handles the Embarcadero gusts without the bulk of a winter coat.

2. 
   02

   Heather grey knit cardigan (year-round SF piece)

   You will wear this daily. Heather grey sits quietly beneath the navy coach jacket, and the knit returns to a year-round SF piece. Wear it under the coach layer, alone in the Mission, or over a tee at Dolores Park.

3. 
   03

   Light grey sheer long-sleeve top

   The sheer fine-knit reads softer than merino on warmer Mission afternoons and layers cleanly under the cardigan for foggy mornings.

4. 
   04

   Warm-white cotton tee

   The short-sleeve option for the day the Mission reaches 26°C / 79°F; it also keeps the evening cardigan from feeling heavy.

5. 
   05

   Dark navy relaxed trousers

   The loose leg reads Mission-bookshop rather than office and moves through wind better than a tight jean.

6. 
   06

   Navy printed midi skirt

   The warmer-afternoon alternative, with enough length to stay useful once the marine layer returns.

7. 
   07

   Off-white chunky sneakers (Hoka or NB-adjacent)

   SF hills are real. Off-white chunky soles hide Mission sidewalk dust and Powell Street cable-car grit better than the bright-white June pair. Hokas for tech-trail aesthetic; Sambas for casual-polished.

8. 
   08

   Cognac structured leather bag

   SF tech culture makes backpacks acceptable, but a cognac structured leather bag reads a notch dressier for Rich Table reservations and still holds a Hydro Flask. Cognac warms the navy-and-grey August palette.

9. 
   09

   Grey knit beanie

   A compact fog-morning layer for the western neighborhoods and early ferry starts.

10. 
    10

    Coral-and-navy silk scarf

    Cuts the afternoon wind without adding sweater bulk and gives the neutral capsule one controlled color note.

11. 
    11

    Sand packable windbreaker

    The dedicated wind-blocking layer for the Presidio or Embarcadero, small enough to live in the bag.

12. 
    12

    Thin black leather gloves

    Optional, but Ocean Beach at 14°C / 57°F with a 20mph wind can feel close to 7°C / 45°F after sunset.

13. 
    13

    Cognac ankle boots

    The evening shoe keeps the same warm leather story as the bag and handles the temperature drop better than sandals.

What to avoid

• Packing 'California in August' as uniformly warm — SF is the continental US exception
• Sandals as primary footwear
• Shorts for full days
• Lightweight athletic wear as a layer — doesn't block wind
• Waiting for an 'SF summer day' — the season doesn't shift
• Expensive boutique stores for emergency fleeces — Uniqlo Union Square is the local supply chain
