Trader consensus on Polymarket tilts toward a Beijing high temperature of 21–23°C on March 28, driven by the latest ECMWF and GFS ensemble forecasts projecting peaks near 22°C amid a persistent high-pressure ridge ushering mild southerly winds and above-normal spring warmth. Recent observations show Beijing's March averages around 13–15°C historically, but this year's anomalous warmth—fueled by weakened Siberian cold outbreaks and urban heat island effects—has pushed recent highs into the low 20s, narrowing model spreads. Differentiation among top outcomes hinges on subtle cloud cover variability and afternoon convective potential, with official China Meteorological Administration updates expected to refine hourly maxima; low odds for extremes reflect minimal signals of cold snaps or heatwaves in surface analyses.
