Trader consensus on Polymarket heavily favors a Beijing high of 19°C (39% implied probability) or 18°C (29%), driven by the latest ECMWF and GFS model runs forecasting mild spring conditions with highs in the upper teens Celsius amid light southerly winds and partial cloud cover. Recent observations show March 22's high at 17.5°C, aligning with a gradual warming trend from early March's cooler 10-12°C averages, influenced by shifting jet stream patterns over East Asia. Historical March data from the China Meteorological Administration indicates typical highs of 12-15°C, but this year's El Niño residual effects have boosted temperatures 2-3°C above normal, positioning 17-21°C as leading outcomes while cooler anomalies remain unlikely per ensemble forecasts.
