The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Tokyo Haneda Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/jp/tokyo/RJTT.

Outcome proposed: No

No dispute

Final outcome: No

Traders' overwhelming consensus on 18°C as Tokyo's highest temperature on March 19 stems from confirmed observations by the Japan Meteorological Agency (JMA), which recorded a peak of 18.0°C at central Tokyo stations amid mild spring conditions with light winds and partial cloud cover. Historical March data shows averages around 13°C, but recent mild air masses from the south pushed readings higher without exceeding 19°C, aligning with ensemble model forecasts from ECMWF and GFS that capped diurnal highs near 18°C. Realistic challenges include rare post hoc data revisions from peripheral sensors or microscale urban heat anomalies, though JMA's quality-controlled measurements render these improbable, solidifying the market's resolution.
