In North Gyeongsang Province, Gyeongju recorded 33.7 C, Gumi 32.6 C, Andong 30.7 C, and Pohang 33.2 C.Meteorologists report that these figures indicate a broader shift in the region's heat patterns.The trend is also evident in historical temperature records.KMA data show that the highest officially recorded temperature in the Daegu–North Gyeongsang region was 40.4 C in Uiseong.
