Forecast models for Tokyo on September 9 indicate a maximum temperature near 30–31°C, driven by southerly flow advecting warm, humid air while widespread cloud cover and thunderstorms limit surface heating and solar insolation. Recent runs show afternoon peaks constrained by precipitation and shifting winds, consistent with historical September variability where unstable patterns often suppress extremes. Trader consensus reflected in the market odds aligns with this guidance from global and regional models, though final resolution depends on official Japan Meteorological Agency observations; updated forecasts tonight or early tomorrow could refine the expected range before resolution.

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.
