Inland areas of South Korea will see daytime temperatures rise above 30 °C this Sunday [1].
The sudden heat spike and the movement of a regional typhoon create a volatile weather pattern for the peninsula. While the heat affects domestic activity, the typhoon's trajectory determines whether the region faces severe storm surges or remains clear.
According to the Korea Meteorological Administration, a high-pressure system extending from the west is bringing clear skies and warm westerly winds [2]. This system is heating the surface and raising temperatures across the interior [2].
Kang Hye-mi, a forecaster at the Korea Meteorological Administration, said that as the region enters the influence of the high-pressure system, strong sunlight and surface heating will cause many areas to see maximum temperatures above 30 °C [1].
Some inland locations may experience temperatures reaching approximately 33 °C [1]. This surge in heat is expected to create a significant diurnal temperature swing, with the difference between morning and afternoon temperatures potentially exceeding 15 °C [1].
Simultaneously, the region is monitoring the first typhoon of the year to move northward toward the Korean Peninsula and Japan [1]. The storm is currently located in the southern sea [1].
Meteorologists said the typhoon is expected to miss South Korea entirely and instead head toward the waters south of Japan [1]. Current atmospheric patterns are steering the system away from the peninsula, reducing the immediate risk of storm-related damage in Korea [2].
“Maximum temperatures above 30 °C are expected in many areas.”
The combination of a high-pressure system and a diverting typhoon suggests a period of stable but intense heat for South Korea. The significant temperature gap between morning and night may increase health risks related to thermal stress, while the typhoon's trajectory shifts the primary weather concern from wind and flood damage to heat management.
