Official forecasts from the National Weather Service highlight a high near 60–62°F for San Francisco on October 10, driven by persistent west-to-southwest onshore flow and marine layer influence that moderates coastal temperatures. This setup aligns with typical fall patterns where cool Pacific air limits daytime warming despite mostly sunny skies. Model consensus shows limited spread, with some guidance reaching the low-to-mid 60s if mixing strengthens, while others hold closer to 59°F under stronger breezes. The market’s emphasis on 62–63°F captures this narrow range of outcomes, as traders weigh the exact peak against historical October variability and the risk of slight forecast revisions before resolution.
