Clear skies and light northerly winds under stable high pressure are driving overnight radiational cooling in the Seoul-Incheon region, positioning the lowest temperature on September 21 near 19°C according to consensus forecasts from the Korea Meteorological Administration and global models. With daytime highs reaching 28–29°C and minimal cloud cover or moisture, temperatures are expected to bottom out in the 18–20°C range overnight as heat escapes efficiently under calm conditions typical of early autumn. This aligns with the market-implied odds favoring 19°C at 47.5%, followed by 20°C and 18°C, reflecting trader assessment of model agreement on these thresholds rather than extremes. No major forecast shifts have occurred in the past 24–48 hours, though final resolution depends on precise hourly observations from Incheon International Airport.

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=rksi
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.
