Recent forecasts from the Korea Meteorological Administration and international models indicate a likely daily maximum of 26–28°C in Incheon on August 30, with 27°C holding the highest market-implied probability. Persistent cloud cover and scattered showers tied to a low-pressure system approaching from the Shandong Peninsula are suppressing daytime heating, keeping values below the late-August climatological average near 29°C. Light winds and high humidity further limit rapid warming, while model consensus shows only modest afternoon recovery. Updated runs over the next 48 hours, particularly once the frontal passage timing is refined, will determine whether the peak reaches 28°C or stays closer to 26°C. Trader positioning reflects this narrow range of outcomes supported by current observational trends and ensemble guidance.

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.
