Recent JMA forecasts show mostly cloudy conditions with modest afternoon shower chances over Tokyo on August 20, keeping maximum temperatures near the seasonal average of 31–32°C amid an above-normal summer pattern driven by a strengthened Pacific High. This setup explains the tight clustering of market-implied probabilities around 30–32°C, as models indicate limited potential for extreme highs or sharp cooling. Persistent high humidity and urban heat-island effects support the slight edge for 31°C, while any late-day convection or minor frontal influence could cap readings at 30°C. Updated guidance from the Japan Meteorological Agency in the next 24–48 hours will refine these thresholds.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 20 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Tokyo Haneda Airport Station, available here: https://www.wunderground.com/history/daily/jp/tokyo/RJTT.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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 JMA forecasts show mostly cloudy conditions with modest afternoon shower chances over Tokyo on August 20, keeping maximum temperatures near the seasonal average of 31–32°C amid an above-normal summer pattern driven by a strengthened Pacific High.
