Korea Meteorological Administration observations confirm Seoul's highest temperature reached 18°C midday on May 4 amid hazy sunshine and light westerly winds that capped solar heating, aligning with high-resolution short-range model consensus projecting no further warming into the evening. Current late-afternoon readings hover at 18-19°C across official stations, with cooling trends under diminishing daylight reinforcing trader lock-in at 100% implied probability for 18°C. This positioning reflects skin-in-the-game assessment of near-resolution data, cooler than the early-May climatological average of around 20°C due to atmospheric stability. Realistic challenges—such as abrupt clearing skies triggering a 1-2°C late heat burst—remain improbable given forecast stability, with final KMA daily maximum report expected post-midnight.
