Recent forecast models from sources including the Global Forecast System show overnight lows in Tokyo hovering near 19–20°C on September 17, with persistent northeasterly flow, widespread cloud cover, and periods of light rain limiting radiative cooling. These conditions, combined with elevated humidity near 85–95%, reduce the potential for temperatures to drop below 19°C while also capping upside surprise from clearer skies. Market-implied odds cluster tightly around 19°C and 20°C because ensemble guidance shows only modest spread in minimum readings, with resolution hinging on the exact timing of any clearing after midnight. Historical mid-September baselines near 19–21°C provide context, but the current pattern favors the narrow range traders currently price most heavily.

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.
