Trader consensus overwhelmingly favors a Tokyo high of 15°C on March 22 (97.9% implied probability), driven by the latest Japan Meteorological Agency (JMA) forecasts and ensemble models from ECMWF and GFS, which converge on mild conditions with highs peaking at 15°C amid light southerly breezes and partial cloud cover. Historical March data for Tokyo shows average highs of 13-14°C, with rare outliers above 17°C, reinforcing this positioning as verified observations from nearby stations align with model outputs. Challenges could arise from an unforeseen warm front or stalled high-pressure ridge boosting temperatures 2-3°C, though low-probability ensemble tails suggest under 2% risk, keeping higher outcomes thinly traded.
