Persistent cloud cover, widespread rain, and high humidity from an active monsoon pattern have kept radiative cooling minimal overnight across the Seoul-Incheon region, anchoring minimum temperatures near 23–25 °C. Official Incheon International Airport observations and model consensus show dew points holding around 23 °C, which limits further drops even as winds remain light. With the daily minimum typically occurring just before dawn under these stable, moist conditions, trader probabilities cluster tightly between 24 °C and 25 °C, reflecting small differences in forecast timing of showers and boundary-layer mixing rather than any larger synoptic shift. Historical August lows at the site average near 23 °C, but the current moist airmass favors the higher end of recent observations.
