**Clear skies and moderate northeasterly winds under a stable high-pressure pattern are positioning Seoul/Incheon for a daytime maximum near 29°C on September 6.** Official forecasts from Incheon International Airport and multiple meteorological sources project a high of 27–29°C with overnight lows around 19–20°C, consistent with current conditions on September 5 showing similar sunny weather and highs of 27–29°C. Light to moderate NE flow (roughly 7–10 m/s) limits mixing while allowing ample solar heating during the 12-hour daylight period, keeping temperatures above the September climatological average high of about 25.8°C but well below extremes. Minimal cloud cover and zero precipitation probability support the market’s heavy weighting toward 28–30°C outcomes, with limited upside risk absent any unexpected shift in steering patterns or humidity.

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.
