Trader consensus at 100% implied probability for a 24°C high in Chongqing on September 11, 2026, rests on official station observations confirming that exact maximum under mostly cloudy skies and light winds. September marks a seasonal transition in the region, with typical daytime highs moderating from summer peaks above 30°C toward the monthly average near 27°C, aided by increased cloud cover and higher humidity that limit solar heating. Multiple forecast models converged on this outcome with minimal spread, consistent with recent observational trends showing stable conditions rather than late-season warming. Resolution hinges on verified daily maximum data from the designated meteorological source, where only an unexpected data revision or station-specific anomaly could alter the result.
