**Persistent heatwave conditions driven by the North Pacific High and Tibetan High are positioning Busan for a daytime maximum in the mid-30s °C on August 6.** These systems promote subsidence, clear skies, and strong solar heating across the Korean Peninsula, with recent observations showing Yangsan (adjacent to Busan) reaching a national record 42.5 °C on August 2. Coastal moderation from sea breezes and higher humidity in Busan typically caps peaks 3–6 °C below inland maxima, aligning with current model guidance of roughly 32–34 °C (around 90–93 °F) from sources like timeanddate and Weather Underground, though some runs indicate potential for 35–36 °C under continued clear conditions. Korea Meteorological Administration heat warnings remain active for the Busan region, reflecting elevated baseline temperatures several degrees above seasonal norms. Trader consensus clusters tightly on 34–36 °C because the heatwave shows little sign of immediate relaxation before the market resolves, while extremes above 37 °C or below 33 °C appear less probable given historical coastal patterns and the latest short-range forecasts.
