Seoul's August precipitation market shows tight clustering around lower-to-mid ranges because the East Asian summer monsoon (Changma) largely tapered off after early August while no typhoon has made a direct landfall near the capital. Southern provinces recorded extreme totals exceeding 900 mm from mid-month systems, yet Seoul has seen only scattered convective showers and heat-wave conditions, keeping cumulative rainfall below the long-term August average of roughly 300–350 mm. With eight days remaining, trader sentiment hinges on whether Typhoon Saudel or subsequent steering patterns deliver organized rainfall bands or whether persistent high pressure maintains mostly dry, hot conditions. Model runs and Korea Meteorological Administration guidance will clarify intensification and track risks that could shift totals across the 150–250 mm threshold.
