**Trader consensus strongly favors a 30°C high for Seoul/Incheon on August 27, 2026, at 97.5% implied probability.** Official Korea Meteorological Administration forecasts and model consensus indicate a typical late-August peak near this threshold under mostly cloudy skies with light winds and moderate humidity, consistent with climatological averages for the region. Current observations show temperatures climbing through the upper 20s to low 30s Celsius during peak heating hours, aligning with ensemble guidance projecting limited daytime warming due to cloud cover and scattered showers. While a 30°C outcome reflects aggregated trader assessment of stable synoptic patterns, scenarios such as faster clearing skies or reduced precipitation could allow readings to reach 31°C or higher, though such shifts remain low-probability based on the latest model runs.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
