At least 16 people have died from heat-related illnesses in South Korea this year, according to health authorities.
South Korea has shattered a 117-year record for the number of sweltering nights in July amid a scorching heatwave.
Temperatures in Seoul did not dip below 29.3 degrees Celsius (84.7 degrees Fahrenheit) overnight, marking the 22nd “tropical night” so far this month, the Korea Meteorological Administration (KMA) said on Thursday.
The KMA defines a tropical night as occurring when temperatures stay above 25 degrees Celsius (77 degrees Fahrenheit) from 6:01pm to 9am the following day.
The number of tropical nights in July is the highest since records began in 1908.
