Official Korea Meteorological Administration (KMA) observations at Busan and Gimhae stations confirm a midday peak of 26°C on May 14, fueled by high-pressure subsidence, clear skies, and peak solar insolation following morning lows near 15°C. This steady diurnal warming under a persistent upper-level ridge—deviating above May's climatological average of 22–24°C—has locked in trader consensus, with hourly data showing temperatures now stabilizing or cooling into evening. Model consensus from KMA short-range forecasts underestimated the warmth due to unanticipated low cloud cover, but current soundings indicate no further intensification. A realistic challenge would require an anomalous sea-breeze reversal driving late-afternoon heating, though upper-air patterns make this improbable; final KMA daily maximum report expected post-midnight.
