Official National Weather Service observations at Houston Hobby Airport recorded a daily maximum temperature of 91°F on September 4, 2026, anchoring the market's complete consensus on the 90-91°F bin. This outcome aligns with regional atmospheric conditions, including moderate humidity and limited cloud cover that permitted afternoon heating near seasonal averages without triggering stronger convection. Trader positioning reflects high confidence in these verified surface measurements, which follow standardized protocols for daily highs. While final quality-controlled data could theoretically shift by a degree due to station calibration or reporting adjustments, such revisions remain rare for established airport sites and would require documented discrepancies beyond current preliminary reports.
