Trader consensus has locked in 15°C as Tokyo's highest temperature on March 22, driven by official Japan Meteorological Agency (JMA) surface observations from central stations like the Tokyo observatory, which recorded a peak of 15°C amid persistent cool northerly winds and cloudy skies typical of early spring. Historical data supports this, with late March highs averaging 13-16°C over the past decade, aligning with current El Niño-influenced patterns suppressing warmth. Scenarios challenging this near-certainty include a rare post hoc data revision from auxiliary stations or measurement anomalies, though JMA verification processes make such shifts improbable, solidifying the market's implied 100% probability.
