Trader consensus overwhelmingly favors a Tokyo high of 13°C on March 25, driven by Japan Meteorological Agency (JMA) forecasts and ensemble models from ECMWF and GFS projecting mild spring conditions under a stable cool air mass, with daytime highs stabilizing around 13°C based on recent soundings and sea-level pressure patterns. Historical March late averages hover near 12-14°C, aligning with current dew points and light winds suppressing warmer advection. This positioning reflects high model agreement, with minimal spread in temperature projections. Realistic challenges include an unforeseen foehn-like downslope warming from Pacific highs or stalled frontal boundary shifting northward, though low-probability per latest 00Z runs.
