Recent forecasts from multiple models indicate highest temperatures in Tokyo on August 30 will likely reach 27–28°C, reflecting the primary driver behind clustered market odds near those levels. A cool front and associated rain system on August 29 has established northerly flow and elevated cloud cover, suppressing daytime heating and keeping surface temperatures below seasonal normals of around 31°C. Clearing skies and lighter winds on the 30th should permit modest recovery through solar insolation, though residual moisture and boundary-layer humidity may cap peaks near the lower end of the historical range. Updated Japan Meteorological Agency and ensemble guidance expected in the next 24 hours could refine these thresholds ahead of market resolution.

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 30 Aug '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.
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 forecasts from multiple models indicate highest temperatures in Tokyo on August 30 will likely reach 27–28°C, reflecting the primary driver behind clustered market odds near those levels.
