Forecast models from the National Weather Service and others indicate mostly sunny skies with light variable winds for San Francisco on October 13, supporting a moderate daily high near the seasonal average of 70.8°F. Coastal marine influences and the Pacific's thermal inertia limit afternoon warming compared to inland areas, positioning the 72-73°F bin as the market leader at 47.5% implied probability while keeping 70-71°F and 74-75°F as viable alternatives. Recent cooling on October 12 has given way to clearer conditions without strong onshore flow or fog, aligning trader consensus with these outcomes. Updated model runs and official briefings will refine the final reading before resolution.
