Traders overwhelmingly favor a highest temperature of 13°C in Tokyo on March 26 (43.5% implied probability), closely trailed by 12°C (26.5%) and 14°C (20.5%), driven by the Japan Meteorological Agency's latest GFS and MSM model ensembles projecting daytime highs in this narrow 12-14°C range amid weak high-pressure influence and light southerly winds. Recent observations show Tokyo's March averages hovering around 13°C historically, with this week's mild 15-17°C anomalies cooling toward seasonal norms as cold fronts recede. Ensemble forecasts highlight low volatility, with 80% of members clustering below 15°C, though 24-hour updates could shift odds if Pacific moisture increases cloud cover and suppresses peaks.
