Recent forecasts from the Japan Meteorological Agency and other models indicate a minimum temperature near 21–24°C in Tokyo on August 30, driven by persistent cloud cover and scattered showers that limit nighttime radiative cooling amid high humidity. This aligns with late-August climatological normals of roughly 22–23°C at the Tokyo station, where recent days have featured above-average rainfall keeping surface temperatures moderated without strong cold advection. Trader consensus around 22°C reflects model agreement on these conditions, though slight variations in cloud timing or wind could shift the observed low by 1°C. The market resolves on official JMA data, with final confirmation expected shortly after the date.

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 30 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 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 the Japan Meteorological Agency and other models indicate a minimum temperature near 21–24°C in Tokyo on August 30, driven by persistent cloud cover and scattered showers that limit nighttime radiative cooling amid high humidity.
