Extreme heat has pushed temperatures in Yangsan to 41.6°C [1] as a rare dry monsoon affects South Korea.
This weather event is significant because it represents a historic breach of temperature thresholds in several regions, signaling a shift toward more volatile and extreme summer climate patterns in the peninsula.
Yangsan has seen temperatures exceed 41°C for two consecutive days [2]. Meanwhile, the cities of Kimhae and Changwon recorded temperatures above 40°C for the first time in their recorded history [3]. Residents in these areas are currently facing what officials describe as an extreme heat trap.
"Yangsan has exceeded 41 degrees for two consecutive days, and Kimhae and Changwon have also broken 40 degrees for the first time, leaving the Gyeongnam region trapped in extreme heat," a YTN anchor said [3].
Meteorologists attribute the surge to a "dry monsoon," a period of insufficient precipitation, combined with basin topography that traps heat. This effect was intensified by a double high-pressure system over the Korean Peninsula, which drove hot air directly into the region [1].
"The Korean Peninsula is being swept by a continuous, record-breaking heatwave," reporter Jung Hye-yoon said [1].
Forecasters warn that this extreme heat is not localized to the south. The heatwave is expected to move toward Seoul and the metropolitan area next week [4]. Local authorities are preparing for the arrival of these high temperatures to prevent heat-related illnesses and infrastructure failures.
“Yangsan has seen temperatures exceed 41°C for two consecutive days.”
The combination of a dry monsoon and specific atmospheric pressure systems creates a 'heat dome' effect. When this occurs in basin terrains, it prevents cooler air from circulating, leading to temperatures that exceed historical norms. The projected movement of this system toward the densely populated Seoul metropolitan area increases the risk of urban heat island effects, potentially straining the city's energy grid and public health resources.
