Trader consensus heavily favors 13°C as Tokyo's highest temperature on March 25, driven by aligned forecasts from the Japan Meteorological Agency and global models like ECMWF and GFS, projecting a mild but cool late-winter day under stable high-pressure influence with light winds and partial cloud cover. Historical March 25 averages hover around 12-14°C, bolstered by current ensemble predictions showing minimal spread (standard deviation ~1°C) amid a jet stream dip suppressing warmth. This positioning reflects low volatility in short-range numerical weather prediction. Realistic challenges include an unforeseen southerly airflow surge or rapid cloud clearance boosting solar insolation by 2-3°C, though upper-air patterns make such shifts improbable below 1% odds.
