Current forecasts from the Korea Meteorological Administration and European Centre for Medium-Range Weather Forecasts anchor trader sentiment around a 24–25 °C daily maximum for Seoul on May 19, with clear to partly cloudy skies and light southerly flow supporting typical late-spring daytime heating at 37.5 °N latitude. This aligns with historical mid-May climatology of 19–22 °C means but sits slightly above average due to recent subsidence and warm-air advection ahead of a weak trough. Ensemble model guidance reveals modest spread: stronger boundary-layer mixing could push readings to 26 °C, while increased cloud cover or an earlier wind shift favors 23 °C. Traders closely monitor the next model runs and official KMA updates, as the narrow resolution window at the Seoul observatory leaves outcomes tightly clustered around the central bins.

This market will resolve to the temperature range that contains the highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 19 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Incheon Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Current forecasts from the Korea Meteorological Administration and European Centre for Medium-Range Weather Forecasts anchor trader sentiment around a 24–25 °C daily maximum for Seoul on May 19, with clear to partly cloudy skies and light southerly flow supporting typical late-spring daytime heating at 37.5 °N latitude.
