Trader sentiment clusters tightly around 15–17°C for Tokyo's highest temperature on March 22, reflecting convergence in ensemble forecasts from the Japan Meteorological Agency (JMA) and global models like ECMWF and GFS, which project peaks of 15.5–17°C under a dominant high-pressure ridge ushering mild continental air. JMA's latest update implies a 16°C maximum amid light winds and partial sunshine, while slight model divergences—ECMWF leaning cooler at 15.8°C due to potential northerly gusts, GFS warmer at 17.2°C from urban heat amplification—drive the razor-thin odds split. Historical March 22 averages hover at 14.5°C, but above-normal spring warmth and low precipitation risk elevate these outcomes, with 1–2°C uncertainty from afternoon cloudiness differentiating the leaders.
