Recent observational data from San Francisco stations indicate a minimum temperature of 60–61°F on September 11, 2026, aligning with the market's dominant 90% implied probability for that bin. This outcome reflects a continuation of above-average overnight warmth driven by persistent high pressure, light west-southwest winds, and marine layer suppression that limited radiational cooling. Earlier September heat, including a 94°F peak on the 9th, elevated baseline temperatures, pushing the daily low well above the 56°F climatological norm. With official National Weather Service and NOAA-verified readings now available, trader consensus has consolidated around the measured value, leaving minimal probability mass on cooler or warmer alternatives absent any post-processing revisions.
