Current forecasts from the Korea Meteorological Administration indicate a mild overnight low near 16°C for Seoul on May 25, driven by typical late-spring transitional patterns with light winds and variable cloud cover. Trader sentiment remains evenly distributed because short-range models show potential for either radiative cooling under clear skies, which could drop readings to 12–14°C, or warmer advection from southerly flow pushing minima above 18°C. Historical May climatology places average overnight lows at 13–16°C, yet day-to-day variability from frontal passages or urban heat effects introduces meaningful uncertainty. Updated model runs over the next 48–72 hours will likely tighten resolution criteria around the 15–17°C range.
