Recent National Weather Service guidance and ensemble models indicate San Francisco’s August 10 high will likely fall in the low 70s, driven by persistent onshore flow and a shallow marine layer that moderates coastal temperatures through cold-water upwelling and westerly advection. Typical August climatology centers near 69 °F, but any thinning of the stratus deck or slight offshore shift could allow modest warming into the mid-70s, while stronger onshore winds or deeper fog would cap readings near 68–69 °F. With leading market bins clustered around 70–73 °F, traders are weighting the narrow range of model solutions and the historical rarity of extremes under prevailing summer marine conditions. Updated NWS forecasts tonight will refine the outcome ahead of tomorrow’s resolution.
