South Korea saw a record hot summer this year with the nationwide average temperature, excluding Jeju Island, coming to 29.1 C in the first 10 days of August, the highest on record, the state weather service said Tuesday.

The reading is on par with the 10-day average of August 2018, making it the hottest first 10-day period of August in 53 years since 1973, when the weather observation network was expanded nationwide, according to the Korea Meteorological Administration (KMA).

The average daily maximum temperature in the first 10 days of this month was 34.4 C, the second highest after 34.7 C recorded in 2018, the KMA said.

The average daily minimum temperature, which is an indicator of night heat, was 24.8 C for the same period, the third highest on record following 25 C in 2022 and 24.9 C in 2018.

The highest temperature recorded during the 10-day period was 42.5 C observed in the southeastern city of Yangsan at 1:26 p.m. on Aug. 2. It was also the highest temperature recorded in the country since 1904, when modern meteorological observations began, according to the KMA.

In total, the daily maximum temperature exceeded 40 C at 32 locations nationwide in the first 10 days of this month, the KMA noted.
