Current forecasts from the Korea Meteorological Administration and global models indicate overnight lows in Seoul around 25–26°C for July 29, aligning with the market's tight clustering on those outcomes amid the ongoing East Asian monsoon. High humidity and variable cloud cover from lingering frontal systems create modest uncertainty in radiative cooling overnight, while typical July climatology shows average minimums near 23–25°C with a standard deviation of roughly 2°C. Recent model runs show limited spread due to stable steering patterns, though afternoon convection or clearer skies could shift the daily minimum by 1–2°C. Traders are weighting these near-term ensemble outputs heavily ahead of updated guidance expected within 48 hours.
