Forecast models from the Japan Meteorological Agency and international sources indicate persistent cloud cover and scattered showers over Tokyo on September 8, driven by a lingering low-pressure system and southerly flow, which will cap daytime heating and keep the maximum temperature near the seasonal average of 28–29 °C. Recent heavy rainfall on September 7 has increased surface moisture and humidity, further moderating peaks despite occasional model runs showing brief afternoon breaks that could push readings to 30–31 °C. Trader consensus around 28–30 °C reflects this narrow range of outcomes, with resolution hinging on the precise timing and intensity of any convective activity monitored by official hourly observations. Updated forecast runs and satellite imagery in the next 48 hours will clarify whether stronger insolation or enhanced cloudiness shifts probabilities.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Tokyo Haneda Airport Station in degrees Celsius on 8 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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 that 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 will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Forecast models from the Japan Meteorological Agency and international sources indicate persistent cloud cover and scattered showers over Tokyo on September 8, driven by a lingering low-pressure system and southerly flow, which will cap daytime heating and keep the maximum temperature near the seasonal average of 28–29 °C.
