Trader consensus on Polymarket reflects tight uncertainty in forecast models for Tokyo's highest temperature on April 4, with JMA's latest 7-day outlook projecting an 18°C maximum under persistent cloudy skies, driving the clustered odds around 17–19°C. Recent late-March warmth, including a 21°C high on March 29 amid building high-pressure influence, combined with JMA's seasonal forecast of above-average temperatures through June due to ongoing warming trends, supports potential for 19–20°C if clouds thin. Differentiating factors include ensemble disagreements among JMA, ECMWF, and GFS models on cloud cover extent and ridge positioning, which dictate solar insolation and near-surface mixing; fuller cloudiness favors 16–17°C, while partial clearing boosts toward 20°C. Daily updates from these agencies through April 2 will sharpen resolution based on Tokyo's official JMA station observations.
