Recent official forecasts from the Korea Meteorological Administration and supporting models indicate a high of 27–28°C in Incheon on August 30, driven by persistent cloud cover, scattered rain, and light winds associated with a nearby low-pressure system. These conditions limit daytime heating relative to typical late-August climatology, when clear skies often push maxima above 30°C. Multiple guidance sources converge on afternoon peaks near 27°C amid 80–100% cloud cover and modest southwesterly flow, with only limited clearing expected. This scientific consensus on modest temperatures under suppressed insolation aligns with trader positioning favoring 27°C and 28°C as the most probable outcomes. Updated model runs and KMA briefings through the evening of August 29 will provide the final observational adjustments ahead of market 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.
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.
