Real-time observations from the Korea Meteorological Administration show Seoul-Incheon temperatures peaking near 26–29°C under partly cloudy skies with light northerly flow on October 11, aligning with model consensus from GFS runs that forecast a daily maximum of 26°C. This exceeds typical mid-October climatology by several degrees amid warm air advection, with dew points and humidity supporting limited further intensification before evening cooling. Trader consensus at 26°C reflects these verified station readings and the absence of stronger southerly steering or clear-sky amplification that could push values higher. Resolution hinges on the official daily maximum from the designated Incheon or Seoul station; minor revisions in post-processing or localized microclimate differences remain the primary variables that could shift the outcome.
