Recent forecasts from the Korea Meteorological Administration and numerical weather models show Busan’s May 17 maximum temperature clustering tightly around 31–32 °C, driven by persistent southerly flow, clear skies, and above-seasonal warmth that has elevated regional temperatures through mid-May. This setup favors strong daytime solar heating and limited cloud cover, while the city’s coastal location and sea-breeze moderation keep values from climbing higher. The market’s closely matched leading outcomes reflect minor model differences in boundary-layer mixing and peak insolation, with climatological May highs typically ranging 20–24 °C serving as a baseline for the current anomaly. Official observations at Gimhae International Airport will resolve the market once the day’s maximum is recorded.
