Persistent heat wave conditions and elevated humidity across South Korea are anchoring trader sentiment for Seoul (Incheon) overnight lows on August 6 near 27–29°C, with the 28°C outcome leading at 32.5% implied probability. The Korea Meteorological Administration continues issuing heat advisories, limiting radiative cooling and sustaining nighttime readings several degrees above the long-term August average low of roughly 23°C. Regional forecast models show broad consensus on this range through the period, though typical 1–2°C uncertainty in short-range guidance and potential shifts in steering patterns or precipitation could favor 26°C or 30°C outcomes. KMA short-term updates over the next 48 hours represent the key data releases likely to refine market positioning ahead of resolution.
