Seoul is expected to experience summer-like heat on Monday, May 18, 2024, with midday temperatures reaching 30°C [1].
The sudden temperature spike and poor air quality pose health risks for commuters and outdoor workers across South Korea.
Weather officials said that the temperature in Seoul was 15.8°C at 7 a.m. [1]. By midday, the temperature is projected to rise to 30°C [1], representing an increase of approximately 15°C throughout the morning [1]. A YTN weather presenter said that commuters should prepare well for the heat when leaving for work.
Other regions are seeing similar trends. Sejong recorded a morning temperature of 14°C [1], while Daegu was at 16.6°C [1]. The heat is expected to be more intense in certain areas, with Daegu projected to reach 34°C and Daejeon hitting 30°C by midday [1].
Beyond the heat, officials said hazardous atmospheric conditions were present. The national UV index is classified as "very high" [1]. Additionally, ozone concentration levels are expected to be "bad to very bad" in most regions [1]. Gwangju and Jeju are the only areas excluded from this ozone warning [1].
Public health advisories typically suggest limiting outdoor exposure during peak sun hours when UV levels are highest. The combination of high heat and poor ozone levels can exacerbate respiratory issues and cause skin damage, making protective gear and hydration essential for the day.
“Seoul is expected to experience summer-like heat on Monday, May 18, 2024.”
The significant diurnal temperature swing and poor air quality indicate a volatile transition into the summer season. The presence of 'bad to very bad' ozone levels, coupled with high UV radiation, suggests that the heat is compounded by environmental pollutants, increasing the risk of heatstroke and respiratory distress for the urban population.
