Latest National Weather Service and ensemble forecasts for San Francisco on October 11 point to a high of 61–66°F under sunny skies with moderate westerly winds, driven by persistent onshore flow of cool marine air from the Pacific that limits daytime warming. This pattern aligns with climatological norms for early October but sits below the 1991–2020 average high of 71°F, reinforcing trader consensus around the 64–67°F bins at combined 77.5% implied probability. Model agreement on minimal cloud cover and light precipitation chances reduces upside risk for 70°F-plus outcomes, though minor shifts in wind direction or timing of any marine layer could adjust the peak by a degree or two before resolution.
