Japan Meteorological Agency observations confirm Tokyo's highest temperature on April 1, 2026, reached exactly 17°C at the central Tokyo station, aligning perfectly with trader consensus and locking in 100% market-implied probability for this outcome. Cool early-spring conditions, including persistent cloud cover and light winds from the north, capped daytime heating despite typical April climatology where highs average 17–19°C; hourly data showed peaks around midday before a late-afternoon drop. This observational certainty from JMA's automated surface measurements leaves negligible room for revision, though rare scenarios like post-audit data corrections or disputes over station-specific readings could theoretically challenge it before market resolution. No further forecast updates expected as the daily record stands firm.
