Forecast consensus from the Japan Meteorological Agency and global models drives the 96.5% market-implied odds for a 20°C low in Tokyo on September 13, projecting overnight minima near 20–21°C under mostly cloudy skies, light northerly winds, and high humidity that limits radiative cooling. Recent stabilization after early September rainfall has produced mild, stable conditions consistent with late-summer climatology for the region, where average September lows hover around 20°C. Traders appear to discount minor model spread or urban heat-island effects that could nudge the official reading slightly higher or lower. The outcome hinges on JMA’s automated station data for the 24-hour period ending at 00:00 JST on September 14; clearer skies or an unexpected cold-air intrusion remain the primary low-probability risks that could shift the minimum below 20°C.

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.
