Forecast models from the National Weather Service and other sources indicate a minimum temperature near 59–62°F for San Francisco on October 5, driven by persistent onshore westerly flow, moderate marine layer influence, and limited nocturnal radiative cooling under partly to mostly clear skies. These conditions align with early-October climatology, where the long-term average low is approximately 55°F, though recent days have featured slightly elevated overnight readings amid regional warmth. Ensemble guidance shows low spread for the overnight period, with minimal risk of stronger offshore winds that could push values higher or colder advection that would drop them below 55°F. Trader positioning favoring 74°F+ or mid-60s bins may reflect uncertainty around exact station readings or resolution criteria rather than current observational trends, as new model runs and official updates from NWS Monterey will refine the outlook ahead of the date.
