**Forecast models for Incheon/Seoul on August 30, 2026, currently cluster daily highs in the 25–28°C range amid late-summer variability, producing the market’s even 18.5% splits across 26–30°C outcomes.** Multiple sources, including Korea Meteorological Administration aviation observations, PredictWind, WeatherBug, and the Met Office, indicate morning rain or overcast skies (50–60% chance) followed by partial afternoon clearing that could allow highs near 27–28°C, while persistent cloud cover or heavier showers would cap temperatures closer to 25–26°C. This spread arises from uncertainty in the timing and intensity of a passing frontal system or lingering monsoon moisture, which modulates insolation, evaporative cooling from precipitation, and boundary-layer mixing. Historical late-August averages near 29°C provide context, yet 2026 trends show a cooler shift with elevated humidity (70–90%) and light winds limiting diurnal warming. Traders weigh updated model runs and official briefings for resolution thresholds, as small changes in cloud timing or rainfall totals can shift the daily maximum by 2–3°C.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Incheon Intl Airport Station in degrees Celsius on 30 Aug '26.
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.
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.**Forecast models for Incheon/Seoul on August 30, 2026, currently cluster daily highs in the 25–28°C range amid late-summer variability, producing the market’s even 18.5% splits across 26–30°C outcomes.**
Multiple sources, including Korea Meteorological Administration aviation observations, PredictWind, WeatherBug, and the Met Office, indicate morning rain or overcast skies (50–60% chance) followed by partial afternoon clearing that could allow highs near 27–28°C, while persistent cloud cover or heavier showers would cap temperatures closer to 25–26°C. This spread arises from uncertainty in the timing and intensity of a passing frontal system or lingering monsoon moisture, which modulates insolation, evaporative cooling from precipitation, and boundary-layer mixing.
