Recent forecasts for Chengdu indicate a daytime high near 32°C on May 18, with partly cloudy skies and isolated showers possible late in the day, creating modest uncertainty that keeps market-implied probabilities clustered between 30°C and 32°C. Model runs from regional meteorological services show slight variations in cloud cover timing and rainfall onset, which can suppress peak temperatures by 1–2°C if showers arrive earlier. Historical May climatology places average highs around 28–30°C, so the current setup reflects warmer-than-normal conditions driven by a persistent southerly flow, yet afternoon convection remains a key variable that could shift the observed maximum. Updated guidance expected from the China Meteorological Administration in the next 12–18 hours will likely refine these probabilities ahead of market resolution.
