Recent forecast models from agencies like the China Meteorological Administration point to a daily maximum temperature in Chengdu on May 19 most likely falling between 30°C and 32°C, driven by typical late-spring warming under partly cloudy skies with light southerly flow and minimal precipitation expected. This narrow band reflects subtle variations in model runs regarding cloud cover, humidity levels, and urban heat island effects at the Shuangliu International Airport station, which serves as the official resolution source. Historical May climatology shows average highs near 28°C with standard deviations of 2–3°C, underscoring the genuine uncertainty that keeps trader-implied probabilities tightly clustered around these outcomes ahead of final observational data.
