**Forecast models indicate a highest temperature in Tokyo on September 7, 2026, most likely between 26–28°C amid persistent heavy rain, thunderstorms, and thick cloud cover.** Southerly to southwesterly winds, high humidity near 90%, and widespread precipitation—driven by a low-pressure system and frontal activity—are suppressing daytime heating by limiting solar radiation and promoting evaporative cooling. Official and ensemble guidance from sources like the Japan Meteorological Agency and global models show afternoon peaks clustered in this narrow range, with hourly data peaking near 27–28°C before showers intensify. This aligns with market-implied odds favoring 27°C (29%), 28°C (20%), and 26°C (19.5%), reflecting trader assessment of the strong consensus on rain-cooled conditions while allowing for minor model spread in exact maxima. Updated runs from monitoring agencies will refine the outlook ahead of the daily high.

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 7 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 indicate a highest temperature in Tokyo on September 7, 2026, most likely between 26–28°C amid persistent heavy rain, thunderstorms, and thick cloud cover.** Southerly to southwesterly winds, high humidity near 90%, and widespread precipitation—driven by a low-pressure system and frontal activity—are suppressing daytime heating by limiting solar radiation and promoting evaporative cooling.
