Current forecasts from Korean Meteorological Administration and international models indicate overnight lows near 21–23°C in Incheon on September 3 under a building high-pressure ridge, with northerly flow and clearing skies after recent showers. This aligns with early-September climatology where average minima hover around 18–20°C but recent runs show slightly elevated values due to lingering warmth. Trader positioning, with 15°C or below at 42.5% implied probability alongside clustered bets near 21–23°C, reflects uncertainty in model spread for minimum temperatures, potential for localized radiational cooling under clear conditions, and historical precedent for occasional sharper drops. Upcoming model updates and official observations will refine these market-implied odds.

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.
