Current short-range forecasts from agencies and models place Busan’s overnight low on September 1 in the 24–26 °C range, consistent with the tightly bunched market probabilities around those values. Persistent high humidity from a weakening frontal boundary, combined with variable cloud cover and light southerly flow off the East Sea, limits radiative cooling after any evening showers. Clearer intervals would favor the lower end near 23 °C, while lingering clouds or residual moisture would hold temperatures closer to 26 °C. Recent heavy rainfall across southern Korea has increased soil moisture, further moderating overnight drops relative to drier climatological baselines. Updated model runs on the final day will refine exact timing of any clearing and thus the precise minimum.
