**Forecast models and official guidance from the National Weather Service indicate sunny conditions and light west-to-southwest winds for San Francisco on October 7, supporting a daytime high most likely in the mid-to-upper 70s.** Recent observations show a warm early-October pattern, with SFO recording 90°F on October 3 and 83°F on October 4, well above the 1991–2020 average high of about 71°F for the date. This stems from persistent high pressure and reduced marine-layer influence, allowing greater daytime heating before the typical afternoon onshore flow strengthens. The closely matched market probabilities across 76–81°F bins reflect genuine uncertainty in peak temperature tied to small variations in wind speed, timing of any marine push, and exact location of the measurement (airport vs. downtown microclimates). Stronger westerlies or earlier fog return could cap readings nearer 76–77°F, while lighter flow or delayed cooling favors 80–81°F. Updated NWS point forecasts and morning model runs will provide the clearest signals ahead of resolution.
