Official observations from the National Weather Service and regional stations recorded a daily maximum of 90–91°F in Austin on October 7 under clear skies and light northeast winds, aligning with model guidance and placing the outcome well above the long-term average high of 85.4°F for the date. This consensus reading, supported by afternoon peaks near 1:52 p.m. local time and minimal diurnal variability, drove the near-certain market pricing. Revisions to the final climate summary, discrepancies between primary stations such as Austin Bergstrom and Camp Mabry, or post-processing adjustments to the daily maximum could still shift resolution if they move the verified high outside the 90–91°F bin.
