Recent official forecasts from the Korea Meteorological Administration point to a maximum of 34°C in the Seoul-Incheon area on August 13 under mostly clear skies, following a prolonged early-August heatwave that brought Seoul peaks near 39°C and national records above 42°C. Market-implied odds cluster tightly around 32–34°C because short-range numerical weather prediction ensembles show modest spread from variables including boundary-layer mixing, coastal sea-breeze timing from Incheon, and residual humidity. Clearer conditions and light winds favor the upper end of that range, while any increase in cloud cover or stronger onshore flow could cap readings at 32°C; these thresholds align with typical model uncertainty two days before verification.
