Trader consensus overwhelmingly favors a Beijing high of 15°C on March 21 (99.8% implied probability), driven by converged forecasts from authoritative models like ECMWF and GFS, alongside China Meteorological Administration outlooks showing cloudy skies and northerly winds capping temperatures around 13-16°C. Historical March data supports this, with Beijing's average highs near 13°C amid typical early-spring chill, reinforced by recent cold air masses from Siberia. Ensemble predictions exhibit low spread, minimizing upside surprises. Realistic challenges include an unforeseen southerly jet stream shift injecting warmer air or urban heat island amplification at the official Pudong station, though such deviations occur in under 5% of similar setups per climatological records.
