Seoul is forecast to reach 37 °C next week as an extreme heat wave moves toward the South Korean capital [1].
This temperature spike triggers a warning level comparable to a major alert, threatening public health in one of the world's most densely populated cities. The situation is exacerbated by high humidity, which is expected to raise the perceived temperature by an additional one to two °C [2].
Weather officials said that the heat wave has already impacted the southern regions of the country. In Yangsan, Gyeongsangnam-do, the daytime temperature soared to 40.3 °C [4]. According to the Korea Meteorological Administration, this marked the first time a formal observation station has recorded temperatures exceeding 40 °C for two consecutive days [4]. Earlier this week, other parts of Gyeongsangnam-do saw temperatures ranging between 38 °C and 40 °C [5].
Currently, the perceived temperature in Seoul is around 35 °C [2]. Experts said there are no mitigating weather factors to cool the region as the heat mass moves northward. The intensity of the upcoming week is expected to surpass previous seasonal norms.
"Extreme heat wave, the problem is that it will get worse in the future," a YTN News anchor said [6].
Reporter Kim Min-kyung of YTN News said that because the forecast for Seoul is 37 °C, a temperature exceeding human body temperature, a heat wave equivalent to a major alert is expected [7].
Local authorities are monitoring the situation as the capital prepares for the surge in temperature. The combination of stagnant air, and high humidity typically increases the risk of heat-related illnesses among elderly populations and outdoor workers.
“Seoul is forecast to reach 37 °C next week”
The northward migration of a 40 °C heat mass from the southern provinces to Seoul indicates a systemic weather pattern rather than an isolated spike. When temperatures exceed 37 °C alongside high humidity, the body's ability to cool itself through perspiration is compromised, increasing the likelihood of heatstroke and placing significant strain on the city's energy grid due to air conditioning demand.
