**Recent forecasts from agencies including the Korea Meteorological Administration and international models converge on a high of 27–29°C for Seoul/Incheon on September 2, 2026, with 28°C emerging as the modal outcome.** This positioning stems from early-September climatology in the region—declining solar angle after peak summer, elevated humidity (80–90%) that limits daytime heating, and light southwesterly winds under partly cloudy skies with only a low (20–30%) chance of showers. Overnight lows near 22–24°C and residual moisture from September 1 rainfall further cap maximum temperatures, while the absence of strong high-pressure ridging or clear skies prevents stronger warming toward 30°C or above. Model agreement on these conditions, updated through September 1, underpins the market’s concentration on 27–29°C outcomes as the most probable range ahead of official observations.

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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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.
