**Trader sentiment reflects high uncertainty in Seoul's remaining August rainfall totals, with closely matched probabilities across the 200–400 mm range centered near the long-term average of roughly 250–350 mm.** Mid-month conditions show lingering East Asian monsoon moisture and scattered convective activity, but the seasonal shift toward drier patterns is underway, tempered by a strengthening El Niño that often suppresses rainfall or alters typhoon tracks across the Korean Peninsula. Key variables include the frequency and intensity of late-month precipitation events, steering patterns influenced by subtropical highs, and any tropical cyclone incursions—factors that can swing totals by 100+ mm in either direction. Official Korea Meteorological Administration short- and medium-range guidance, combined with ensemble model spreads, currently supports this balanced outlook without strong signals for extremes.
