Ongoing heatwave conditions driven by the North Pacific High and warm, humid southerly flows are sustaining elevated temperatures across southeastern South Korea, positioning 34°C as the market's leading outcome at 43% implied probability. Busan recorded a notable 39°C high on August 1—the highest in over a century—reflecting stronger-than-average warming that has carried into early August. Short-range Korea Meteorological Administration guidance and extended models currently favor daytime maxima near 31–32°C for August 5 under mostly sunny skies, yet persistent tropical night patterns and model spread around intensification keep 33–35°C viable. Coastal sea breezes may moderate peaks slightly relative to inland areas, while any delayed frontal passage could shift the distribution.
