Traders favor 13°C (28.5% implied probability) for Tokyo's highest temperature on March 26, driven by the Japan Meteorological Agency's latest forecast pinpointing a daytime high near 13°C under persistent northerly winds and scattered clouds from a lingering high-pressure system. This edges out 14°C (19%) and clustered rivals like 12°C, 15°C, and 11°C (all ~16.5%), as ensemble models from ECMWF and GFS converge on 12–14°C amid cooler-than-average late-March conditions—historical highs average 14.5°C but are suppressed this year by upstream cold air advection. Uncertainty lingers from potential afternoon clearing boosting diurnal warming by 1–2°C, per recent soundings, keeping 16°C+ viable at 16.5% despite low odds.
