Recent National Weather Service and AccuWeather model runs indicate San Francisco’s August 6 high will likely settle near 70–73 °F, aligning with the market’s heaviest weighting on those bins. Persistent onshore flow and a moderate marine layer are expected to limit daytime warming along the immediate coast, consistent with climatological August averages of 69 °F. Minor variations in sea-breeze strength, low-cloud coverage, and any weak high-pressure ridging could shift the peak by a degree or two; stronger winds or earlier fog burn-off would favor the 74–75 °F outcome, while thicker stratus would cap readings closer to 68–69 °F. Updated model guidance and morning observations tomorrow will provide the final inputs for resolution.
