Recent forecasts from multiple models indicate a suppressed high around 27–28°C for Tokyo on August 30 due to persistent cloud cover, light rain, and northerly flow associated with a passing frontal system, which has reduced solar insolation and advected cooler maritime air. This deviates several degrees below late-August climatology of 30–31°C. Trader consensus clusters tightly on these values because ensemble spreads remain modest, with differentiation hinging on precise timing of any afternoon clearing or shifts in boundary-layer moisture. New JMA and global model runs over the next 48 hours will likely resolve whether the peak reaches 29°C or stays at 26°C.

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 a suppressed high around 27–28°C for Tokyo on August 30 due to persistent cloud cover, light rain, and northerly flow associated with a passing frontal system, which has reduced solar insolation and advected cooler maritime air.
