Persistent heat wave conditions driven by the North Pacific High continue to influence southeastern Korea, with the Korea Meteorological Administration maintaining heat wave emergency warnings for Busan as of early August. Recent confirmation of a 39°C peak on August 1 has elevated trader focus on whether similar intensity persists into August 4 or yields to moderating coastal sea breezes and variable cloud cover that often cap daily maxima near 33–36°C. Model consensus points to highs in this narrow range, with differentiation hinging on exact timing of any frontal passage or localized wind shifts that could prevent or enable brief spikes above 35°C. Updated KMA short-range guidance and ensemble runs over the next 48 hours will likely refine the implied probabilities clustered around 34–35°C.
