This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Tokyo Haneda Airport Station in degrees Celsius on 1 Sep '26. The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rjtt If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event which there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent weather forecasts for Tokyo on September 1, 2026, consistently point to an overnight minimum near 23–25°C under mostly cloudy skies, light northeasterly winds, and high humidity typical of late-summer subtropical conditions. Multiple models show the daily low occurring in the early morning hours before daytime heating pushes highs to 28–33°C. Trader consensus favoring 24°C reflects this narrow forecast range, while lower-probability outcomes around 20°C or below would require an unseasonal cold surge absent from current guidance. Minor variations in cloud cover or localized precipitation could nudge the exact minimum, but official agency outlooks and ensemble runs support the market-implied clustering around 23–24°C.
