Trader sentiment for Chengdu's highest temperature on March 23 remains tightly clustered across outcomes from 10–19°C, reflecting high forecast uncertainty from divergent global ensemble models amid variable spring synoptic patterns over the Sichuan Basin. The China Meteorological Administration's latest guidance points to a high around 15–18°C under partly cloudy skies with light northerly winds, while ECMWF ensembles show a 40% spread between 12–19°C due to potential cold air intrusions from Mongolia. GFS runs skew slightly warmer toward 18–19°C, influenced by lingering subtropical high pressure, but historical March data (mean high 16.5°C) and urban heat island effects in Chengdu add volatility, keeping 18°C and 19°C+ odds neck-and-neck at 27% each. Key resolution hinges on afternoon insolation and any convective activity.
