Recent forecasts from multiple models indicate a high near 24°C in Tokyo on September 18 under persistent cloud cover and northerly winds, which limit daytime heating amid a broader cool, moist pattern. This setup follows several days of rain and suppressed temperatures, with afternoon maxima expected in the 23–25°C range depending on exact cloud timing and wind strength. The Japan Meteorological Agency and global ensembles show limited warming potential before a shift later in the weekend, aligning trader consensus with 24°C as the modal outcome while leaving room for 23°C or 25°C if conditions evolve. Updated model runs and observational trends over the next 48 hours will refine these probabilities 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 18 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 high near 24°C in Tokyo on September 18 under persistent cloud cover and northerly winds, which limit daytime heating amid a broader cool, moist pattern.
