Recent forecasts for Incheon and Seoul on September 16 indicate overnight lows clustering around 14–19°C under clear to partly cloudy skies and light easterly or northeasterly winds, supporting the tight market clustering around 16°C and 17°C. Radiative cooling under high pressure and minimal cloud cover favors the lower end of that range, while any increase in humidity or slight wind mixing could hold minima near 17–18°C. Model consensus shows limited spread for this period, with no significant frontal passages or tropical influences expected to alter the pattern before resolution. Traders appear to weigh the balance between typical mid-September climatology and the current stable anticyclonic setup, where small differences in boundary-layer conditions determine whether the minimum settles at 16°C or edges higher.

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.
