This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 30 Mar '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.Trader consensus on Polymarket favors a Tokyo high of 19°C at 40% implied probability, closely trailed by 20°C (23.5%) and 18°C (22%), driven by the Japan Meteorological Agency's (JMA) March 29 evening forecast projecting exactly 19°C amid mostly cloudy skies that limit solar insolation and daytime heating. Yesterday's observed high of 21°C exceeded expectations, reflecting a recent warm air mass over the Kanto region above the seasonal March norm of 17°C, but today's overcast conditions and 20% precipitation odds early cap upside potential per updated JMA guidance showing a possible 21°C max. Forecast models show tight clustering with minor uncertainty from cloud breaks; real-time observations from Haneda and central Tokyo stations will refine the peak through late afternoon.
