SEOUL - South Korea issued its first-ever emergency heatwave alert on July 12 under a new warning system introduced in 2026, advising people to halt outdoor activities and keep cool.
The new warning system was introduced to better deal with a rising number of heatwaves in South Korea, which have become longer and more intense, officials said.
An emergency alert is issued when areas experiencing a heatwave are forecast to hit perceived temperatures of 38 deg C or an actual temperature of 39 deg C for one day.
“The Korea Meteorological Administration issued an Emergency Heatwave Warning at 10am today (9am Singapore time) for two cities in southern North Gyeongsang province – Gyeongsan and Pohang,” said chief Lee Mi-seon at a press briefing.
“This marks the first time it has been issued since the system took effect,” she added.
The affected areas saw temperatures reach the emergency criteria over the weekend, Lee said.
“An emergency heatwave warning does not simply mean the weather is extremely hot,” Lee said.
“It indicates conditions in which even healthy people face a significantly elevated risk of serious harm, including heat-related illness and death.”
People engaged in outdoor activities should stop immediately and move to a cool place and no one, including children or pets, should be left inside a vehicle, she added.
KMA data show the average annual number of heatwave days in the country has more than doubled to 19 over the past five years, from eight in the 1970s.
The average annual number of tropical nights has also jumped from four to 14 over the same period.
A heatwave day is defined as one with a maximum temperature of at least 33 deg C, while a tropical night is one when the overnight low remains 25 deg C or above.
The new system comes as Europe endures a scorching summer, after a June heatwave shattered temperature records across the continent.
France recorded more than 2,000 excess deaths during the June heatwave, and 300 during the high temperatures in late May, according to official figures.
The Eiffel Tower and other Paris landmarks closed early over the weekend and cycling’s Tour de France shortened a stage for the first time in its history.
Oceans have experienced their hottest June on record and could set fresh highs in the months ahead, the European Union’s Copernicus Marine Service said in July.
Warmer oceans intensify tropical storms and add more moisture, which can fall as heavy rain.
Adding to the mix is the return of El Nino in 2026, a natural climate phenomenon that warms Pacific Ocean surface temperatures and typically occurs every two to seven years. AFP
