Persistent rain and extensive cloud cover from a slow-moving frontal system are the dominant factors moderating overnight temperatures in Tokyo, limiting radiative cooling and supporting minimums near 21–22 °C. Northerly flow advecting cooler maritime air, combined with high humidity near 95 %, further dampens diurnal temperature range while heavy precipitation (forecast totals exceeding 100 mm on some models) adds evaporative cooling. Recent days have shown similar patterns with observed lows of 19–21 °C amid above-normal rainfall. Ensemble guidance and JMA updates through the weekend will refine the exact threshold, with slight model spread in boundary-layer moisture and wind strength creating the narrow separation between the leading market outcomes.

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 rain and extensive cloud cover from a slow-moving frontal system are the dominant factors moderating overnight temperatures in Tokyo, limiting radiative cooling and supporting minimums near 21–22 °C.
