Confirmed Japan Meteorological Agency (JMA) surface observations at Tokyo stations, including Haneda Airport, recorded the daily minimum temperature of 14°C during early morning hours on April 22 under partly cloudy skies and mild southerly winds, driving trader consensus to a 100% implied probability for this outcome. Hourly readings show subsequent daytime warming amid stable high-pressure influence, preventing further drops, aligning with resolved forecast model ensembles from JMA and ECMWF that initially varied slightly around 14–15°C due to cloud cover uncertainties. Mid-April climatological norms place average lows near 11°C, but current mild conditions support the positioning. Rare challenges like data revisions or anomalous late cooling remain improbable, with JMA's final daily summary pending.
