Recent Korea Meteorological Administration forecasts for August 16 project daytime maxima near 32–33°C under mostly cloudy skies with only 20% precipitation odds, consistent with typical late-summer monsoon moisture and high humidity across the Seoul-Incheon region. These conditions favor a daily high clustered around 29–30°C once localized effects like afternoon sea breezes or brief cloud thickening are factored in, aligning with the market’s strongest implied probabilities on those exact thresholds. Ensemble guidance shows limited model spread on intensification of heat, though any earlier frontal passage could moderate readings toward 28°C. Updated KMA short-range guidance and regional station observations over the next 48 hours remain the key near-term catalysts.
