Seoul is expected to reach a daytime high of 32 °C this Friday as early summer heat affects western South Korea [2].
This sudden temperature spike creates immediate health and comfort challenges for residents, particularly due to a sharp contrast between morning and afternoon temperatures.
The YTN News weather team said that Seoul's temperature was approximately 18 °C during the morning broadcast [1]. However, the city is projected to climb to 32 °C [2], which would surpass the previous record for the year. This creates a day-night temperature difference of roughly 15 °C [6].
The heat is not limited to the capital. Other western regions are forecasted to see temperatures around 30 °C [3]. Specifically, Daejeon and Jeonju are projected to reach 31 °C [4]. In contrast, the East Sea coast in Gangneung is expected to be cooler, with a projected temperature of 25 °C [5].
Weather officials said that the current heat is driven by seasonal high pressure and strong solar radiation. Along with the rising temperatures, the UV index is classified as "very high" [7]. Residents are also advised to monitor ozone levels as the heat persists.
"Today is the hottest weather of the year so far," a YTN reporter said. The reporter said that Seoul's temperature had reached 30.3 °C, which is seven degrees higher than the average for this time of year [9].
The period of intense heat is expected to be short-lived. Forecasts indicate that rain will arrive mid-week, specifically on Wednesday, across the nation [8].
“Seoul is projected to climb to 32 °C, which would surpass the previous record for the year.”
The arrival of 30 °C+ temperatures in mid-May indicates an accelerated transition to summer weather in South Korea. The 15 °C temperature swing is particularly noteworthy as it increases the risk of seasonal illness, while the high UV index and ozone levels necessitate public health warnings regarding sun exposure and air quality.
