Clear skies and light easterly winds under high pressure are enabling strong daytime solar heating across the Seoul-Incheon region today, with official Korea Meteorological Administration forecasts calling for a maximum near 28°C. This setup favors a peak in the mid-to-upper 20s Celsius, as minimal cloud cover and low humidity support efficient surface warming without significant marine moderation at Incheon stations. Model consensus and historical mid-September analogs align with 26–27°C outcomes most probable, while slight variations in exact timing of the daily maximum or localized sea-breeze effects could tip the reading to 28°C or hold it at 25°C. Updated observations through the afternoon will clarify 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.
