Recent official forecasts from the Korea Meteorological Administration indicate a minimum temperature of 24°C for Seoul and Incheon on August 13 under mostly clear to partly cloudy conditions with negligible precipitation risk, positioning this outcome as a market favorite alongside 23°C. These values align with typical late-summer climatology for the region, where overnight radiative cooling under stable high-pressure patterns often produces lows in the low-to-mid 20s Celsius amid daytime highs near 33°C. Ensemble model guidance shows limited spread, with minor downward revisions possible if clearer skies enhance cooling overnight, while the absence of incoming frontal systems or monsoon influences supports the tight clustering of implied probabilities around these thresholds. Updated model runs and KMA briefings over the next 24 hours will provide the key data points likely to influence trader adjustments before resolution.
