Trader consensus heavily favors under 150 mm of total August precipitation in Seoul, reflecting observed rainfall patterns well below the long-term climatological average of roughly 350 mm. Official monitoring from the Korea Meteorological Administration shows predominantly light accumulations, with Seoul receiving only 20–60 mm from late-month stationary front activity that delivered far heavier totals farther south. This aligns with the broader 2026 summer monsoon distribution, where moisture corridors and low-pressure remnants favored Chungcheong and Honam regions over the capital area. The market-implied probability near 95% for the lowest bracket underscores consistent model runs and station data through month-end. Only substantial upward revisions in finalized KMA figures or overlooked localized convective events could realistically shift resolution.
