Pronóstico: Highest temperature in Seoul (Incheon) on August 5?

Platform comparison

Market context

The key event is the highest temperature at Incheon International Airport on 5 August, and the market is effectively asking whether the station prints an unusually hot late-summer reading. With a 0% crowd-implied yes price, the market is treating a top-end outcome as essentially impossible, but local forecasts argue for a materially hotter-than-average day across the Seoul metro area: SBS says Seoul is under a severe heat-wave warning, with a daytime high near 38°C and heat persisting day and night[1].

Historical framing points the other way: August is already one of Seoul’s hottest months, and published August averages sit around the high 20s Celsius for daytime highs, with humidity and rain common[15][19]. Holiday Weather cites an August record high in Seoul of 38.2°C[15], which shows that exceptional heat is within the historical envelope even if it is not the norm. For a station-based market, the relevant question is not the citywide forecast alone, but whether Incheon Airport’s coastal exposure and local cloud or sea-breeze effects cap the peak below the hotter inland readings.

The catalysts to watch are the official short-range forecast and any late-morning updates to heat warnings or shower timing from the Korea Meteorological Administration[6][11]. SBS notes showers may still affect parts of western regions today while the broader western plains stay very hot[1], which matters because brief cloud cover or onshore flow can trim the daily maximum at the airport more than it does inland. Traders should also watch whether nearby Seoul forecasts hold near 38°C or soften through the morning, because that will shape whether Incheon follows the city surge or settles several degrees lower[1][2].
