Trader sentiment clusters tightly around 12–14°C for Tokyo's March 25 high temperature, driven by the Japan Meteorological Agency's (JMA) latest forecast model ensemble implying a peak near 13°C amid mild southerly advection from a weakening high-pressure ridge. Differentiating factors include subtle divergences in global models—ECMWF leaning slightly warmer at 14°C due to clearer skies, while GFS holds cooler at 12°C with residual cloudiness—against Tokyo's historical March 25 average of 13.2°C (1981–2010 baseline). Urban heat island effects could nudge readings higher at central stations, but low confidence in 17°C+ stems from jet stream positioning suppressing extremes, with final JMA updates expected to sharpen odds before resolution.
