Trader sentiment for San Francisco’s August 5 high centers on 72–75°F bins because National Weather Service and AccuWeather guidance shows persistent onshore flow and a moderate marine layer limiting daytime heating to near-normal August values around 70–73°F. Recent clear, sunny conditions have allowed modest warming above the long-term average, supporting the slight edge for 72–73°F, while light westerly winds and possible patchy fog keep higher outcomes below 25% probability. Model consensus indicates minimal offshore flow or ridging that could push readings into the mid-70s, creating tight differentiation between adjacent bins driven by small shifts in cloud cover or boundary-layer moisture. Resolution hinges on the official maximum at the downtown or airport station, with latest model runs expected to refine the range before sunset on the 5th.
