1. It’s official: South Korea is experiencing its hottest June ever, and by a significant margin.

   According to the Korea Meteorological Administration on Sunday, regions across the country recorded an average of 2.4 heat wave days from June 1 to 20, which is four times the average from 1991 to 2020.

   The previous record was set in 2018, when there were 1.5 heat wave days. A heat wave day, as defined by the KMA, is when daytime temperatures soar above 33 degrees Celsius.

   This year’s first heat wave warnings, issued when high temperatures 33 degrees or more are projected to continue for two or more days, were announced June 10 in regions including Daegu, Ulsan and Gyeongju in North Gyeongsang Province. This was a week earlier than last year’s first warnings, issued June 17, 2023.
