Current atmospheric conditions over Chongqing, driven by a stable high-pressure ridge and moderate southerly moisture flow, point to a maximum temperature most likely between 23°C and 25°C on May 18. Official forecasts from the China Meteorological Administration indicate light cloud cover and light winds that could limit peak heating by 1–2°C compared to clear-sky scenarios, creating genuine uncertainty reflected in the closely matched market-implied odds for those three outcomes. Historical mid-May baselines for the city average near 24°C, with recent surface observations showing no strong warming trend or cold-front passage that would shift the distribution. Traders are closely monitoring the next model runs and afternoon temperature readings, which will determine the precise daily high used for market resolution.
