Recent official forecasts and model consensus from sources like the Korea Meteorological Administration point to a daily maximum near 28–29°C in Incheon on September 5, driven by persistent northeasterly winds, mostly clear to partly cloudy skies, and modest daytime heating under seasonal early-autumn conditions. This aligns with the market’s tight clustering around 28–30°C outcomes, as traders weigh subtle differences in boundary-layer mixing, cloud cover, and exact steering patterns that could shift the peak by 1–2°C. Historical September averages near 26°C provide context for the slightly above-normal readings expected, while low precipitation chances reduce cooling influences. Updated model runs and official station observations in the final 48 hours will refine the precise threshold for market resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
