Recent forecast models from agencies like the Korea Meteorological Administration indicate Seoul's overnight low on July 27 will likely settle near 24–26°C amid persistent summer monsoon humidity and light southerly flow that limits radiative cooling. Scattered showers or cloud cover expected late on the 26th could trap heat and nudge the minimum higher, while clearer breaks might allow brief drops toward 23°C. These closely matched market-implied probabilities reflect model spread in boundary-layer moisture and timing of any nocturnal rain, with traders weighing historical July climatology (average lows near 23–25°C) against the latest ensemble runs showing modest day-to-day variability. Updated guidance on the 26th will refine steering patterns and precipitation chances ahead of market resolution.
