Recent Korea Meteorological Administration forecasts indicate clear skies and a maximum of 34°C for Seoul and Incheon on August 13, driven by stable high-pressure conditions typical of late summer that promote daytime radiative heating without significant cloud cover or precipitation to moderate temperatures. Market-implied odds center on 33°C as the most probable outcome, consistent with climatological baselines for the region where August highs average near 31–32°C but can reach 34°C under persistent anticyclonic flow. Ensemble model spreads, potential easterly wind shifts, and subtle moisture increases introduce uncertainty around exact peak values, while the recent early-August heatwave peak has begun moderating, leading traders to weight outcomes near the forecast consensus.
