South Korea braces for heatwave beyond 'Eoseoseo' marker, with highs up to 35 degrees

South Korea is bracing for continued heatwaves, with temperatures expected to remain high even after the traditional end of summer. The period around August 23rd, known as 'Eoseoseo' (meaning 'heat retreats'), typically signals a cooling trend, but this year, the 'Eoseoseo magic' is not anticipated.

According to the Korea Meteorological Administration, daytime high temperatures nationwide are forecast to reach between 30 and 35 degrees Celsius (86 to 95 degrees Fahrenheit) on August 23rd. This is significantly higher than the average temperatures for this time of year, which typically range from 27 to 31 degrees Celsius (81 to 88 degrees Fahrenheit). The persistent heat is attributed to the inflow of hot and humid air from the North Pacific High.

While some inland areas in the north and central regions, as well as western Jeonbuk and parts of Chungnam, are expected to receive scattered showers in the morning and afternoon, these are unlikely to bring significant relief. The forecast indicates that after the rain, high humidity levels will persist, leading to continued muggy conditions. The expected rainfall amounts range from 5 to 40 millimeters in affected areas.

Residents are also advised to be cautious of strong winds and high waves in the waters around Jeju Island and the southern part of the West Sea. A strong wind and high wave advisory has been issued for the waters off Jeju Island, with these conditions expected to continue until late afternoon on August 23rd. The prolonged heatwave is a continuation of a trend seen last year, when the average temperature on 'Eoseoseo' day was the highest recorded since 1973.
