Recent rain events tied to a frontal system are shaping trader sentiment for Seoul's October precipitation totals, with the 85mm+ range leading at 36.5% implied probability. As of mid-month, early October remained largely dry under unseasonably warm conditions before 10-50mm fell across the Seoul metro area on October 12-13, per Korea Meteorological Administration guidance. Historical October averages hover near 52mm, but extended forecasts indicate additional moderate rainfall mid-to-late month that could push cumulative totals above the long-term baseline. Model consensus favors this wetter trajectory over drier outcomes, though steering patterns and any further frontal passages introduce uncertainty in exact accumulation.
