**Persistent summer heat and stable atmospheric conditions position 29°C as the market's leading outcome for Chongqing's lowest temperature on August 23, 2026, with 72.5% implied probability.** Official forecasts from the Chongqing Meteorological Bureau and models such as those referenced by WeatherBug and Worldmeteo project daytime highs of 36–39°C under partly cloudy skies with scattered afternoon thunderstorms, followed by overnight lows clustering near 27–29°C. Recent observations show prior nights bottoming at 26–27°C amid high humidity (55–70%) and light winds, limiting radiative cooling. Subtropical summer conditions, including urban heat retention and the absence of strong frontal systems or significant rainfall to refresh the air mass, sustain elevated minimums. Historical August baselines around 26°C provide context, but the current heat wave—with multiple days above 37°C—has kept overnight recoveries high. Traders appear to weigh the consensus of late-model runs and agency guidance favoring a minimum near or above 28°C over cooler outliers. Key upcoming data include updated evening forecasts and official minimum readings, which could shift probabilities if localized convection or clearer skies enhance cooling.
