Recent heat wave conditions across the Korean Peninsula, driven by persistent high-pressure systems and elevated humidity typical of late summer, are keeping overnight minimum temperatures elevated in the Seoul-Incheon region. Korea Meteorological Administration forecasts and ensemble models indicate a likely daily low near 27–28°C for August 7, consistent with current observations around 26–27°C and climatological baselines for early August. This positions the market-implied odds, with 28°C leading at 46.5%, reflecting limited cooling potential before any frontal passage. Updated short-range guidance from KMA and regional model runs expected in the next 24–48 hours will refine the exact minimum, as small shifts in wind patterns or cloud cover could alter the outcome within the 27–29°C cluster.
