South Korea is using speaker drones and turning airport terminals into cooling shelters as record heat sweeps the country.
South Korea is battling an unprecedented wave of dangerously hot weather that has forced local leaders to launch flying drones with loudspeakers and open air-conditioned airport terminals as public cooling shelters. The severe heatwave has brought dangerous heat levels across the entire nation, pushing daytime temperatures past forty-two degrees Celsius and breaking modern weather records that go back over one hundred years. With extreme heat making simple daily activities dangerous, millions of people are fleeing their hot homes to seek safety inside cool public places. Government officials have declared the heat emergency a national disaster and mobilized all available resources to keep residents alive, protect elderly farmers, and prevent widespread heat illnesses.
The crisis is gripping cities and rural countryside areas across South Korea, from the bustling capital of Seoul to agricultural regions like North Gyeongsang Province and the southeastern city of Yangsan, which recorded a historic high of 42.5 degrees Celsius. Because temperatures in many neighborhoods barely drop below thirty degrees even at night, public spaces with free air conditioning have become life-saving refuges. Major transport centers like Seoul’s Gimpo Airport have seen large crowds of residents gathering in terminal halls to sit, rest, and sleep where cool air is flowing freely without cost. Meanwhile, in outdoor farming zones, government workers are flying high-tech surveillance drones equipped with loudspeakers and thermal imaging cameras over crops to spot elderly workers who might pass out in the scorching sun.
The life-threatening weather conditions escalated dramatically during the first week of August 2026, forcing weather authorities to issue their highest-level emergency heat warnings across the country. In response to the growing health risks and rising hospital visits, government agencies launched new emergency safety programs on Thursday to protect citizens. Outdoor baseball games were canceled after fans fainted in stadium seats, historical guard ceremonies at national palaces were paused, and community groups set up thousands of cooling centers across neighborhoods.

Addressing top government leaders during a national emergency response meeting, President Lee Jae Myung stressed the severity of the crisis, stating, “Extreme heat on a scale we have never experienced is continuing day after day. Heatwave conditions once seen only in foreign news reports have now become our reality”. Explaining why public spaces have become so popular for families trying to stay cool, a resident sheltering inside Seoul’s Gimpo Airport told reporters that the airport is a “perfect place to rest without spending any money,” adding, “I come here from time to time with my friends whenever the weather gets too hot”. Describing how difficult it is to step outdoors during peak afternoon hours, office worker Ju Dong-yeol explained, “it is too hot to be outside doing anything,” sharing that “I can’t think of anything else to do other than stay in air-conditioned places like home, shopping malls and cafes”.
The underlying reason for these unusual emergency measures is that extreme weather patterns are causing dangerous heat to trap heavy air over the Korean peninsula, making indoor areas without working air conditioners unsafe for human health. In agricultural villages, most farmers are elderly citizens who often stay in the fields too long without drinking enough water. The speaker drones fly directly over farmland, broadcasting clear voice messages urging elders to take mandatory rest breaks and step into the shade. By combining high-tech drones in the countryside with open airport shelters in the cities, South Korea hopes to protect its citizens until the dangerous heat finally breaks.
