Recent high-resolution numerical weather prediction runs from the Korea Meteorological Administration and major global ensembles have converged on an overnight minimum temperature of 17°C for Seoul on June 2, producing the market's overwhelming 99.1% implied probability for that outcome. Early June climatology in the region typically features lows near 16–18°C under transitional spring-to-summer conditions with moderate humidity and variable cloud cover, and current model guidance shows no significant deviations from this baseline. The strong consensus reflects limited uncertainty in short-range forecasts this close to the observation window, though minor shifts remain possible if unexpected changes in radiative cooling, wind patterns, or local advection occur before the minimum is recorded.
