Persistent heavy rain and overcast skies from a frontal system over the Kanto region are elevating overnight minimums in Tokyo for September 20, limiting radiative cooling under high humidity and northerly flow. Japan Meteorological Agency guidance and ensemble models show a forecast minimum of 21°C against seasonal normals near 19°C, with several runs clustering at 21–22°C amid 90–100% precipitation probabilities. Minor model spreads in timing and intensity of rainfall, plus boundary-layer moisture, differentiate the tightly matched leading outcomes at 21°C and 22°C. Traders are weighting official agency data and recent model consensus over historical baselines given the active weather pattern.

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 20 Sep '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.
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.Persistent heavy rain and overcast skies from a frontal system over the Kanto region are elevating overnight minimums in Tokyo for September 20, limiting radiative cooling under high humidity and northerly flow.
