Trader consensus on Polymarket reflects near-certainty (100% implied probability) for Chengdu's highest temperature reaching 23°C or higher on May 15, driven by the latest China Meteorological Administration forecasts projecting a daytime maximum around 25°C amid light rain and mostly cloudy skies, with morning lows near 18°C. This aligns with mid-May climatology in the Sichuan Basin, where average highs hit 27°C and topographic warmth trapping sustains peaks even under overcast conditions—evidenced by May 14's observed 25°C high in similar weather. Model ensembles from CMA and international sources show tight agreement on limited cooling. Realistic challenges include prolonged heavy precipitation or sudden cool air advection suppressing afternoon heating to 22°C, though upper-level ridge stability makes this unlikely. Hourly observations from Shuangliu Airport station will finalize resolution via official records.
