Recent ensemble forecasts from the Korea Meteorological Administration and global models highlight a lingering summer heat pattern over southern South Korea, with warm-air advection and high pressure supporting daytime maxima near 33–35°C in Busan on August 8. Marine influence from the Korea Strait, variable afternoon cloud cover, and sea-breeze timing introduce the key uncertainty that keeps the top three outcomes clustered between 20–34% implied probability. Historical August baselines near 30–31°C provide context, while ongoing tropical-night conditions and minimal precipitation chances in short-range guidance sustain trader focus on the upper end of the distribution. New model runs and updated KMA briefings over the next 48 hours will likely refine these thresholds ahead of resolution.
