Current ensemble forecasts from global and regional models indicate a daily maximum in Chengdu of 32–34°C on May 22, with the highest probabilities clustered around 33°C. Subtropical high pressure and warm southerly flow are driving afternoon temperatures above seasonal norms of 27–29°C, while scattered late-day convection and basin humidity may cap peaks near the upper end of that range. Model consensus shows limited spread due to stable steering patterns, yet small shifts in timing of cloud cover or localized thunderstorms could differentiate outcomes between 32°C and 34°C. Traders are therefore weighting recent runs that place the most likely maximum at 33°C, consistent with the city’s typical late-May warming trend under similar synoptic setups.
