**Current forecasts from the Korea Meteorological Administration (KMA) and aligned global models point to a minimum temperature near 26–28°C for Incheon/Seoul on August 5, reflecting typical midsummer high-pressure dominance with light winds and limited overnight radiative cooling under humid, partly cloudy skies.** This pattern keeps surface temperatures elevated, consistent with August climatology where overnight lows commonly stabilize in the mid-20s°C absent typhoon influences or cold frontal passages. Urban heat island effects in the Seoul-Incheon corridor further moderate cooling. Recent short-range model runs show minimal day-to-day shifts, supporting the market’s concentration on 27°C (41.5%) and 28°C (29.5%) outcomes, while the 26°C share (13%) accounts for slight forecast uncertainty in humidity or cloud cover. No major weather systems are expected to alter the baseline through the resolution window.
