Trader consensus overwhelmingly favors a highest temperature of 13°C in Tokyo on March 25, driven by Japan Meteorological Agency (JMA) forecasts and ensemble weather models projecting mild conditions with highs capped at 13-14°C amid persistent northerly winds and seasonal norms. Historical data shows late March averages around 12-13°C at Haneda Airport, the market's likely reference station, with verified observations rarely exceeding 15°C this early in spring. Supporting evidence includes stable upper-air patterns from ECMWF and GFS models, indicating low volatility. Realistic challenges would require an abrupt shift to southerly flow or unforecasted frontal warming, though current guidance shows under 1% probability for 15°C or higher.
