Trader consensus heavily favors a Tokyo high of 16°C on March 22, driven by the latest Japan Meteorological Agency (JMA) forecast predicting a daytime maximum around 16-17°C under high-pressure influence, aligning with ECMWF and GFS model runs showing mild southerly flow displacing recent cooler air masses. Historical March 22 averages hover near 14°C, but above-normal sea surface temperatures in the East China Sea and a weakening jet stream have boosted spring warmth, positioning 15-17°C as frontrunners with 96.5% implied probability combined. Recent developments include a stabilizing ridge pattern confirmed in today's 12Z model updates, reducing outlier risks like 18°C+, though urban heat islands could nudge readings higher by late afternoon at official Haneda or Nerima stations.
