Forecasts from the National Weather Service and supporting models project a daytime high near 60°F for San Francisco on October 10, driven by persistent onshore westerly flow and marine-layer influence that limits warming despite mostly sunny to partly cloudy skies. This setup favors the closely matched leading bins of 62-63°F and 64-65°F, as modest differences in wind strength, cloud timing, or boundary-layer mixing could shift the peak by a degree or two. Historical October averages near 71°F underscore the current anomalously cool regime, with no offshore flow or clear-sky amplification expected to push readings higher. Resolution hinges on official observations from downtown or airport stations once the full diurnal cycle completes.
