South Korea sizzles under record heatwave, with 10.2 days of tropical nights on average

South Korea is grappling with an intense and prolonged heatwave, with temperatures soaring across the nation. On August 3rd, Seoul recorded a high of 37°C, while other areas experienced highs between 33°C and 39°C. Heatwave advisories are in effect for most of the country, with "extreme heatwave" warnings issued for parts of the southern and southeastern regions, where temperatures are expected to exceed 39°C and feel like 38°C or higher.

The sweltering conditions have led to a record number of tropical nights this year. From June 1st to August 1st, the average number of tropical nights nationwide was 10.2 days, the highest recorded since 1973. This surpasses the previous record of 9.7 days set in 2024. The average national temperature during this period was also the second highest on record at 24.6°C.

While brief showers are forecast for some inland areas, meteorologists believe they will offer little relief from the oppressive heat. The Korea Meteorological Administration warned that even if temperatures temporarily drop during a shower, humidity levels will remain high, making the heat feel even more intense once the rain stops.

Authorities are strongly advising residents in areas under extreme heat advisories to suspend or postpone outdoor activities and work. They recommend seeking cool environments, staying hydrated, and resting frequently to prevent heat-related illnesses. The prolonged extreme weather poses significant risks to public health and daily life across the country.
