Trader consensus on Polymarket overwhelmingly favors a Tokyo high of exactly 13°C on March 20, driven by the Japan Meteorological Agency's latest forecast models projecting daytime peaks around 12-14°C amid persistent cool northerly winds and cloudy skies from a lingering low-pressure system. Historical March data from the JMA shows Tokyo averages of 12-15°C, aligning with this positioning, while ECMWF and GFS ensembles similarly cluster near 13°C with low variance. Scenarios challenging this include an abrupt southerly foehn wind surge—common in the region—or shortwave ridging boosting insolation, potentially pushing temps to 15°C+, though current upper-air patterns make such shifts unlikely below 5% probability per model spreads.
