South Korea's capital Seoul has recorded 26 tropical nights in a row – with the country's measure of nights when the temperature remains above 25 degrees. This is shown by statistics published on Friday.
There is no cold air coming down from the north and in combination with being affected by the warmer side from the southwest, the temperature continues to stay around 25 degrees or more, says Youn Ki-han, head of Seoul's meteorological institute.
Since South Korea began collecting weather data in 1907, it has only recorded as many warm nights in a row on one previous occasion, in 2018, but the weather institute counts the latest record as a benchmark in its statistical compilation.
Large parts of the world have experienced a summer characterized by extreme temperatures, which led the UN Secretary-General António Guterres to warn last month of an "epidemic of extreme heat".
