Recent official forecasts from the Korea Meteorological Administration indicate a daytime high of 28–29°C for Incheon on September 6 under mostly clear skies and persistent northeast flow, aligning with consensus model outputs showing similar values across regional guidance. This positioning reflects stable high-pressure conditions and moderate onshore advection that limit afternoon heating, following current readings near 29–30°C on September 4. Differentiation between 29°C and 30°C hinges on subtle factors such as exact cloud-cover timing, boundary-layer mixing depth, and minor variations in wind speed, which can shift peak temperatures by 1°C within forecast uncertainty ranges. Traders appear to weigh these variables against historical early-September baselines around 27–29°C, with upcoming model updates from agencies like KMA likely to refine odds before 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.
