This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 11 Apr '26. 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. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Japan Meteorological Agency (JMA) observational data from Tokyo stations, including Haneda Airport (RJTT), confirm a peak temperature of 25°C reached midday under partly cloudy skies and moderate southerly winds, driving trader consensus to a near-certain 100% implied probability for this outcome on Polymarket. Late-afternoon forecast updates from JMA and global models like ECMWF and GFS revised earlier 27°C projections downward, reflecting stabilized atmospheric conditions with increasing cloud cover limiting further warming. Resolution hinges on final Wunderground archives for April 11 highs at RJTT. Realistic challenges include a rare post-peak heat spike from clearing skies or data discrepancies, though diurnal cooling and historical April patterns make 26°C+ highly improbable.
