Trader sentiment for Chengdu's July 21 peak temperature clusters around 38–40 °C because short-range forecast models show a continuation of the current mid-July heat wave, with afternoon highs influenced by subtropical monsoon flow, weak steering winds, and high humidity that limits nocturnal cooling. Historical July averages near 30–34 °C provide context, yet recent station observations exceeding 37 °C and ensemble guidance showing modest warming potential through the weekend keep the 39 °C outcome narrowly favored. Key variables include cloud cover timing, any localized thunderstorm development that could cap temperatures, and official China Meteorological Administration verification at the primary urban station. New model runs and updated guidance expected within 48 hours will likely refine these tightly bunched probabilities.
