**Observational data from Shenzhen meteorological stations recorded a daily maximum of 31.7–32°C on September 9, 2026, under mostly sunny conditions with light easterly winds and low precipitation, aligning with the market's near-certain 32°C outcome.** Subtropical early-September climatology supports this range, with typical highs near 31–33°C and minimal model spread in short-range guidance from agencies like the China Meteorological Administration. The consensus reflects verified station measurements rather than forecasts, with traders assigning negligible probability to deviations given the completed observation window. A realistic challenge would require an official revision from the primary reporting station due to quality control, sensor calibration, or definition of "highest temperature" across multiple sites, though such adjustments are uncommon once preliminary data stabilize.
