Recent South Korean heatwave conditions, with official Korea Meteorological Administration records exceeding 40°C in parts of the country earlier in August, have shaped trader focus on Seoul-Incheon maxima near the seasonal norm of 32–34°C. Short-range forecasts indicate mostly cloudy skies and a 20–24% precipitation chance for August 14, with model consensus centering on 33–34°C highs driven by persistent high pressure, moderate easterly flow, and elevated humidity that limits radiative cooling. Minor differences among 31–33°C outcomes hinge on uncertain afternoon cloud thickness and any localized thunderstorm development, which could suppress peaks by 1–2°C; updated KMA guidance and ensemble runs will refine these variables ahead of market resolution.
