**Trader sentiment for the lowest temperature in Seoul (Incheon) on August 18, 2026, has coalesced overwhelmingly around 24°C.** This reflects the Korea Meteorological Administration’s (KMA) official short-range forecast, which explicitly lists a daily minimum of 24°C for the region under mostly clear to partly cloudy conditions with light winds and minimal precipitation. Incheon International Airport observations and regional model guidance align closely, showing overnight lows stabilizing near this threshold amid typical late-summer humidity levels of 70–85% and no significant cold-air advection or frontal passages expected overnight. Historical August climatology for the area supports average lows of 22–24°C, providing additional context that the current pattern is not anomalous. Because resolution hinges on verified KMA station readings (typically the lowest hourly or daily minimum between 00:00–24:00 KST), traders view the outcome as highly constrained once the forecast window closes. Scenarios that could realistically shift the result—such as localized cooling from unexpected showers, instrument calibration differences between Seoul and Incheon sites, or rapid model revisions—are considered low-probability given the stability of recent guidance and the narrow uncertainty range in current ensemble runs.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Incheon Intl Airport Station, available here: https://www.wunderground.com/history/daily/kr/incheon/RKSI.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
