Recent KMA forecasts for Incheon and Seoul on August 12, 2026, project a daytime maximum of 32°C under mostly clear to partly cloudy conditions with light northeasterly winds, aligning closely with observed midday readings near 29–30°C. This consensus stems from post-heatwave atmospheric stabilization, including easterly flow across the peninsula that has moderated temperatures after earlier peaks exceeding 37°C. Traders assign near-certainty to the 32°C outcome because official short-range guidance shows minimal upside potential from model runs and no significant warm advection expected before evening. A realistic shift would require an unforeseen late-day surge from localized heating or forecast revisions pushing the high to 33°C, though current observations and probability of precipitation near zero make such changes improbable.
