Official National Weather Service observations recorded a maximum temperature of 76°F at both downtown Los Angeles and Los Angeles International Airport on September 6, 2026, aligning precisely with the market-implied 76-77°F outcome at near-certainty. This result fell 8°F below the 1991-2020 normal high for the date amid cooler-than-average marine layer influence and onshore flow, consistent with recent model guidance showing limited warming potential. Verified station data from authoritative monitoring networks leaves minimal room for revision, though traders recognize that minor adjustments in final quality-controlled records or station-specific criteria could theoretically alter edge cases in lower-probability bins.
