Seoul temperatures are expected to rise to approximately 32 °C on June 1, 2026, as summer heat intensifies across South Korea [1].
This sudden temperature spike signals an early onset of extreme summer weather, potentially breaking seasonal records and increasing the risk of heat-related health issues for urban residents.
YTN weather reporter Yun Su-bin said the current temperature in Seoul has already climbed to 29.2 °C [1]. While some reports suggest a peak of 30 °C for the capital [3], other forecasts indicate the city could reach 32 °C [1]. Yun said that if the temperature hits 32 °C, it may break the record for the highest temperature of the summer so far [1].
The heat is not isolated to the capital. The YTN weather team said that Daegu is also expected to reach 32 °C during the day [3]. Current temperatures across the region are tracking between one °C and four °C higher than the historical average [1].
Despite the heat, some regions will experience precipitation. Forecasts indicate that the Gangwon mountain regions and southern inland areas will see showers ranging from five to 10 mm [1]. These localized convective showers are a result of the seasonal intensification of heat interacting with atmospheric moisture.
Residents in the southern inland areas are advised to prepare for both high temperatures and sudden rainfall. The combination of intense heat and humidity often leads to volatile weather patterns during the transition into the full summer season.
“Seoul temperatures are expected to rise to approximately 32 °C”
The arrival of 32 °C temperatures as early as June 1 suggests a deviation from typical seasonal norms in South Korea. When temperatures exceed historical averages by up to four °C this early in the season, it can lead to increased energy demand for cooling and a higher frequency of convective rainfall, which often causes localized flash flooding in mountainous terrains like Gangwon.
