Trader consensus overwhelmingly favors a high of 15°C in Tokyo on March 22, driven by synchronized forecasts from the Japan Meteorological Agency and global models like ECMWF, projecting daytime maxima around 14-16°C under a stable cool air mass from the north. Historical March data shows Tokyo averages 12-15°C highs, with current upper-air patterns suppressing warmer advection. Ensemble predictions converge tightly, reflecting low model spread and minimal convective activity. Realistic challenges include an unforeseen southerly wind shift or frontal passage boosting temperatures to 17°C+, though satellite imagery and soundings indicate scant likelihood amid prevailing synoptic stability.
