Latest numerical weather prediction models from sources including the China Meteorological Administration point to a daily maximum near 33–34°C in Chengdu on August 16, driven by typical late-summer subtropical monsoon flow, moderate humidity, and variable cloud cover over the Sichuan Basin. These conditions produce closely spaced market-implied odds because modest differences in afternoon convection timing or boundary-layer mixing can easily shift the peak temperature by 1–2 °C. Historical August climatology shows frequent 32–35 °C readings, while urban heat-island effects and topographic trapping add further uncertainty; traders are therefore weighting the next model runs and official guidance expected later today.
