Trader sentiment reflects high uncertainty in Seoul's remaining August rainfall amid the East Asian summer monsoon's variable tail and potential typhoon influences. Early-month data show limited accumulation under persistent high pressure and heatwave conditions, with Korea Meteorological Administration forecasts indicating low precipitation probabilities through mid-August. Historical averages range 250–350 mm, but late-month steering patterns and any recurving tropical systems could add substantial totals via enhanced moisture convergence or orographic lift. Model consensus remains split on intensification windows, supporting tightly clustered market-implied odds across 150–500 mm bins. Updated ensemble runs and typhoon tracks will likely drive near-term shifts.
