Persistent rain and extensive cloud cover forecast for Tokyo on September 20 are expected to limit overnight radiative cooling, keeping the daily temperature range narrow and anchoring the minimum near 21–22°C. Official model guidance shows a steady influx of moist northerly flow with high humidity exceeding 90 percent and minimal diurnal swing, as daytime highs are projected only slightly above the overnight low around 22–24°C. This pattern contrasts with clearer conditions that would allow greater cooling toward 20°C or below. Trader consensus on the 21°C and 22°C outcomes reflects the tight clustering of ensemble forecasts around these values, with resolution depending on the precise timing of any brief clearing or heavier rainfall bands that could nudge the recorded minimum by 1°C. Updated Japan Meteorological Agency guidance ahead of the date will be the key near-term driver.

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.
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.
