Current model consensus from agencies including the Korea Meteorological Administration favors a minimum near 20 °C in Incheon on September 6, driven by the recent replacement of the North Pacific high with cooler, drier northeasterly flow that began on September 4. This pattern supports clear to mostly clear skies and modest overnight radiative cooling, placing the most likely low between 19–21 °C. Historical early-September minima average near 18 °C, so the current setup sits slightly above climatology yet remains sensitive to small shifts in wind timing or cloud cover. Updated ensemble runs and the next official KMA briefing will clarify whether the floor settles at 19 °C or holds near 20–21 °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=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.
