Recent National Weather Service point forecasts and model consensus for San Francisco on October 13 indicate a sunny afternoon with light northwest winds and minimal marine layer influence, supporting a daily high in the mid-70s Fahrenheit. This aligns with the market's overwhelming 97% implied probability for the 74-75°F bin, reflecting traders' assessment of official guidance and real-time observations over historical October averages near 71°F. Clear skies and dry northeasterly flow have limited cooling, though any strengthening onshore breeze or earlier fog intrusion could cap readings below 74°F and shift probabilities. Upcoming NWS updates and final hourly observations will determine resolution against the 74-75°F threshold.
