Recent National Weather Service and model guidance for San Francisco on October 2 points to a high near 73°F under mostly cloudy skies driven by a persistent marine layer and moderate onshore flow. This setup, typical for early October, limits solar heating and keeps temperatures close to the 71.6°F climatological average while introducing variability from cloud thickness and wind strength. Trader odds cluster around 71–75°F because small shifts in marine layer depth or afternoon clearing could easily push the daily maximum one or two degrees either side of the forecast value. With resolution only two days away, updated model runs and afternoon observations will be the key catalysts for any further movement in the tightly bunched probabilities.
