**Trader consensus overwhelmingly favors a 21°C minimum for Seoul on June 18, reflecting current official forecasts from the Korea Meteorological Administration (KMA) and aligned models showing overnight lows stabilizing near that level under mostly cloudy skies with light winds and minimal cooling.** Daytime highs are expected to reach 26–31°C amid typical early-summer humidity, consistent with recent observations and seasonal baselines where mid-June lows average 17–20°C but have trended slightly warmer this period due to persistent high-pressure patterns. The strong market-implied probability (93.5%) stems from tight model agreement on the morning low recorded between 3–9 AM KST, with limited variance in ensemble runs. Realistic challenges include unexpected nocturnal cloud cover or a brief rain event enhancing radiative cooling, though current guidance assigns low odds to deviations below 20°C before resolution.

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 Jun '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.
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.**Trader consensus overwhelmingly favors a 21°C minimum for Seoul on June 18, reflecting current official forecasts from the Korea Meteorological Administration (KMA) and aligned models showing overnight lows stabilizing near that level under mostly cloudy skies with light winds and minimal cooling.** Daytime highs are expected to reach 26–31°C amid typical early-summer humidity, consistent with recent observations and seasonal baselines where mid-June lows average 17–20°C but have trended slightly warmer this period due to persistent high-pressure patterns.
