Official meteorological observations from San Francisco stations, including downtown and airport sites, recorded a daily maximum temperature of 68°F on October 12 under clear skies, light variable winds, and stable high-pressure conditions that suppressed warming. This aligned with National Weather Service forecasts projecting below-normal coastal highs in the mid-to-upper 60s, consistent with recent cool marine air influence and the absence of offshore flow or solar enhancement. Trader consensus at 100% for the 68-69°F bin reflects these verified readings and historical climatology showing typical October maxima near 70°F. Resolution criteria based on official daily maximums leave little room for revision unless post-analysis uncovers rare instrumentation discrepancies.
