Recent Japan Meteorological Agency forecasts highlight persistent rain and extensive cloud cover over Tokyo on September 20, driven by a stationary front and northerly flow that limits solar insolation and suppresses daytime heating. These conditions typically cap maximum temperatures 2–4°C below September climatological averages near 26°C, with model consensus centering on peaks of 23–25°C amid heavy precipitation and high humidity. Trader-implied probabilities cluster tightly around these values, reflecting uncertainty in exact diurnal maxima as ensemble runs vary slightly on timing and intensity of showers. Updated model guidance expected in the next 24–48 hours could further refine the 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.
