Latest ensemble forecasts from ECMWF and GFS models project Chengdu's highest temperature on April 18 at 28-29°C under partly cloudy skies with light winds, anchoring trader consensus at 29°C (38% implied probability) and 30°C (26%). This reflects a persistent mid-April warm anomaly in the Sichuan Basin, where a stable upper-level ridge has suppressed typical stratus clouds, enabling recent highs near 29°C on April 17 amid sunny conditions—well above the 22°C April climatological average. The China Meteorological Administration's Chengdu Shuangliu International Airport station readings will resolve the market; overnight short-range updates may adjust for any convective activity, though dry stability favors the leading outcomes.
