Trader consensus on Polymarket heavily favors a Tokyo high of 13°C at 36% implied probability, driven by the latest Japan Meteorological Agency forecast and ECMWF model ensemble mean projecting that exact peak amid mild early-spring conditions. Differentiating factors include subtle variations in cloud cover and southerly winds: fuller cloudiness from a weak high-pressure ridge could cap at 12°C (27.5%), while clearer skies and stronger sea breezes might lift it to 14°C (23.5%). Historical March 25 averages hover around 13.5°C, with current upper-air patterns showing minimal cold-air intrusion, though short-term model divergences highlight 1-2°C uncertainty ahead of tomorrow's hourly updates.
