Recent Korea Meteorological Administration guidance projects a Seoul daytime maximum near or above 25 °C on May 18 under a strengthening high-pressure ridge. This pattern favors subsidence, clear skies, and modest southerly warm-air advection from the Yellow Sea, lifting readings above the mid-May climatological average of roughly 22–23 °C. Model consensus shows limited spread, with only modest cooling possible if a weak frontal boundary arrives earlier than expected. Traders have therefore assigned the highest implied probability to the 25 °C-or-higher bin, while still pricing a meaningful chance for 24 °C if advection remains weaker than anticipated. Updated short-range runs and official briefings before resolution will determine final positioning.
