Korea Meteorological Administration observations confirm Seoul's highest temperature on April 22 reached 18°C midday, with current readings stabilizing around 17–18°C under partly cloudy skies and light winds, aligning with forecast model consensus from short-range guidance showing no further intensification potential. This trader consensus at near-certainty reflects real-time station data from central Seoul sites, where maximums rarely exceed projections late in the day amid typical spring diurnal cycles and moderating humidity levels around 40%. Realistic challenges would require an unusual late-afternoon heat burst from prolonged clear skies or urban heat island effects pushing isolated readings to 19°C, though evening cooling and updated hourly forecasts make this improbable; final KMA daily summary expected by midnight KST.
