Current forecasts from the Korea Meteorological Administration and major models indicate a maximum of 26–28°C in Incheon on August 30, driven by increased cloud cover, 40–60% rain chances, and moderate southerly winds that limit daytime insolation and convective heating. High humidity and overnight lows near 23°C further constrain the diurnal range, keeping peaks below recent 29–30°C readings. Trader consensus clusters tightly on 27°C (33.5%) and 28°C (26%) because ensemble spreads remain narrow this close to the event, though minor shifts in steering flow or timing of showers could push the outcome to either adjacent bin. Official KMA updates and refined model runs over the next 48 hours will provide the key resolution signals.

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.
