**Current forecasts from the National Weather Service and private models point to a mild overnight low near 58–62°F for San Francisco on October 7, supported by persistent high pressure and mostly clear skies with light westerly winds.** This aligns with the recent warm spell across the Bay Area, where above-normal temperatures have dominated early October and model consensus shows minimal cooling overnight. Historical climatology places the average daily minimum around 55°F, but 2026 conditions have run several degrees warmer, reducing the chance of sub-55°F readings. The market-implied emphasis on 72°F or higher reflects trader assessment of upside potential if the ridge strengthens further, while the cluster of probabilities in the mid-50s to low-60s captures the base forecast range and typical model spread. Updated NWS guidance and morning observations on October 6–7 will be the next key inputs likely to shift positioning.
