Recent model runs for Busan on August 8 show high uncertainty in peak daytime heating, with consensus favoring 33–35°C amid typical late-summer subtropical high pressure. Coastal sea breezes and variable humidity moderate maximums relative to inland areas, while any increase in cloud cover or residual monsoon moisture could cap readings near 33°C. Conversely, clearer skies and stronger insolation under stable anticyclonic flow support brief spikes toward 35°C or higher, consistent with historical August extremes that occasionally reach the mid-30s. Forecasters expect updated KMA and global ensemble guidance within 48 hours to clarify steering patterns and boundary-layer conditions that will determine the exact daily maximum.
