Recent forecasts from multiple models indicate Tokyo's overnight low on September 18 will likely settle near 19–20°C under mostly cloudy skies and light northerly winds, with minimal radiative cooling overnight. Persistent cloud cover from a weak frontal influence and recent regional rainfall have suppressed daytime heating while preventing sharp temperature drops, aligning closely with historical September averages for the area. Trader consensus on the 20°C outcome reflects these stable atmospheric conditions and limited model spread, though minor shifts in wind direction or clearing skies could nudge readings toward 19°C or 21°C depending on the precise timing of any precipitation. Official JMA observations will determine the exact minimum.

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.
