Recent forecasts from the Korea Meteorological Administration and global models indicate peak temperatures in Busan on August 16 will likely fall in the 27–28°C range, driven by persistent North Pacific High influence bringing warm, humid air alongside increasing cloud cover and a 20–30% chance of precipitation that limits daytime heating. These conditions align with historical late-August baselines near 29°C while current steering patterns and regional sea surface temperatures moderate extremes. Model consensus remains tight but can shift with updated runs expected within 24 hours; traders weigh variables like wind direction and humidity levels that determine whether maxima reach the upper or lower end of the clustered probabilities.
