Official observations from the Japan Meteorological Agency (JMA) at Tokyo's Haneda Airport station—the market's resolution source—confirm the highest temperature on April 3 reached exactly 19°C, driving the 100% market-implied probability on this outcome. This aligns with early April climatological norms, where daily highs average 18–20°C under typical spring high-pressure systems and mild southerly flows, as seen in recent JMA surface analyses showing stable atmospheric conditions. Trader consensus reflects this verified data, backed by real-money positions. Realistic challenges would require a rare official data revision from instrument error or quality control, though JMA protocols minimize such risks; no further updates are expected as the daily record finalizes by evening.
