Trader consensus favors mild spring conditions in Tokyo, with market-implied odds tightly clustered around 13°C (30.5%) to 16°C (16.5%), driven by Japan Meteorological Agency's latest forecast projecting a daytime high near 14°C amid partly cloudy skies and light southerly winds. Differentiating factors include ensemble model divergence—ECMWF leaning cooler at 13°C due to incoming mid-level trough, while GFS hints at 15°C from warmer Pacific air advection—compounded by Tokyo's urban heat island effect boosting nighttime recoveries. Historical March 25 highs average 13.8°C (1981-2010 baseline), but recent cool snaps have trimmed tails for extremes, with key updates expected from 18Z model runs sharpening resolution odds.
