Korea Meteorological Administration's latest short- and medium-range forecasts project a precise morning low of 15°C for Seoul on May 15, driving the 99% market-implied probability amid an early summer heatwave with daytime highs near 29–30°C under a persistent high-pressure ridge. Clear skies and light southerly winds limit radiative cooling overnight, aligning with model consensus from KMA's numerical weather prediction systems and historical mid-May averages of 13–16°C at official Seoul stations. Trader consensus reflects this skin-in-the-game alignment with authoritative data, though realistic challenges include unexpected cloud incursions raising the minimum or drier air enhancing cooling to dip toward 14°C before dawn—final resolution hinges on verified observations from 3–9 a.m. local time.
