Recent forecasts and observations from the Korea Meteorological Administration and international models indicate an overnight minimum of 25°C in Incheon under partly cloudy conditions with light westerly winds and high humidity, aligning closely with the 98% market-implied probability. This consensus stems from consistent model runs showing no significant nocturnal cooling or frontal passage, consistent with late-August climatology for the region where typical lows range 23–26°C. Traders have converged on this outcome given stable atmospheric conditions and real-time station data. An unforecasted surge in cloud cover or measurement variance at the official Incheon site could still shift the recorded low by 1°C.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
