**Dominant dry conditions through mid-September, backed by sparse rainfall observations and mostly clear forecasts for the final week, have driven the strong market consensus on sub-75 mm totals.** Official monitoring shows minimal accumulation to date, well below the typical September climatological average of roughly 150 mm, with only trace or light amounts recorded on scattered days and no significant frontal passages or typhoon influences. Short-range models from agencies like the Korea Meteorological Administration indicate predominantly stable high-pressure patterns through late September, limiting convective activity and keeping daily precipitation chances low except for isolated light showers around September 25. With just eight days remaining, even moderate additional rain would struggle to push the monthly total above the leading bracket, reinforcing trader positioning around the observed deficit. Resolution awaits the finalized KMA monthly figure for Seoul.
