Official forecasts from the Korea Meteorological Administration and Incheon International Airport observations indicate a peak temperature near 30°C on September 3 under clear to partly cloudy skies with light northerly winds and minimal cloud cover, limiting daytime heating moderation. Recent model runs show consistent surface temperatures in the 29–31°C range during peak afternoon hours, consistent with early September climatology for the region where highs typically reach the low 30s Celsius absent strong frontal systems or heavy precipitation. The market’s heavy weighting toward 30°C reflects this narrow forecast consensus, with limited upside risk from unexpected warming or measurement variability at the Incheon station. Updated guidance through the afternoon will refine any minor deviations near the 31°C threshold.

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 3 Sep '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.
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.Official forecasts from the Korea Meteorological Administration and Incheon International Airport observations indicate a peak temperature near 30°C on September 3 under clear to partly cloudy skies with light northerly winds and minimal cloud cover, limiting daytime heating moderation.
