Current forecasts from the Korea Meteorological Administration and major models indicate a high of 28–29°C for Incheon on September 7 under persistent high pressure, clear skies, and light northeasterly winds that limit cloud cover and moisture. These conditions favor strong daytime solar heating with minimal evaporative cooling, while overnight lows near 19°C reflect efficient radiational cooling typical of early September. The tight market split between 28°C and 29°C captures residual uncertainty in peak timing and exact boundary-layer mixing, with lower probabilities for 30°C+ reflecting limited potential for warmer advection or reduced wind. Updated model runs and official guidance issued in the next 24–48 hours will likely refine the outcome.

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.
