Trader consensus overwhelmingly favors a 19°C high temperature in Seoul on April 30, driven by the Korea Meteorological Administration's (KMA) midday short-range forecast projecting a daytime peak of 19°C at Incheon International Airport station—the market's resolution source via Wunderground data—amid mostly cloudy skies, light westerly winds, and 20% afternoon precipitation odds that cap solar heating. Current observations at Seoul stations and the airport align with 19–20°C maxima, consistent with late-April climatological norms of 18–20°C following mid-month warm spells. Model ensembles show hourly peaks near but below 20°C before evening cooling. Realistic challenges include unexpected sky clearing for intensified insolation or a southerly wind shift introducing warmer air masses, though low-probability given steering patterns; final airport data expected post-midnight.
