Ongoing extreme heat across South Korea, driven by a strengthened North Pacific High and descending easterly winds linked to Typhoon Dolphin, continues to elevate temperatures in the southeast as of early August 2026. Busan’s coastal location typically moderates peaks relative to inland sites like Yangsan through sea breezes, yet recent KMA data show highs in the upper 30s amid persistent tropical nights and high humidity. Short-range model consensus points to daytime maxima near 31–33 °C on August 9, with limited intensification risk before any frontal passage. These verified conditions underpin the tight clustering of market-implied probabilities around 31–32 °C, while uncertainty in exact steering patterns and local boundary-layer mixing keeps lower-probability outcomes for 30 °C or 34 °C+ viable until final observational data.
