Recent forecasts for Tokyo on August 27 indicate overnight lows ranging 23–27°C amid scattered thunderstorms and high humidity from a passing frontal system, with models diverging on cloud cover timing and wind speeds that control nocturnal radiative cooling. Leading market odds near 26–27°C reflect this narrow spread, as persistent cloudiness and rain suppress temperature drops below typical August minima around 24°C while urban heat retention and dew points near 24–25°C limit further cooling. Stronger consensus on daytime highs near 28–32°C anchors the overnight floor, though revised model runs or clearer skies could shift the minimum toward 25°C or hold it at 27°C. JMA and global ensemble updates will refine these thresholds ahead of resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Tokyo Haneda Airport Station in degrees Celsius on 27 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rjtt
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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 for Tokyo on August 27 indicate overnight lows ranging 23–27°C amid scattered thunderstorms and high humidity from a passing frontal system, with models diverging on cloud cover timing and wind speeds that control nocturnal radiative cooling.
