South Korea expects a mix of cool morning temperatures and significant midday heat across the peninsula on June 1, 2024 [1].
This weather pattern marks the transition to full summer conditions. The shift brings a volatile temperature range that affects daily commutes and public health due to rising ultraviolet radiation and ozone levels [1].
Early morning temperatures for the commute are forecast to remain mostly below 20 °C [1]. Specific readings at 7 a.m. include 18.4 °C in Seoul and 18.8 °C in Gwangju [1]. Gangneung reported a slightly warmer start at 21.6 °C [1]. This follows a preceding weekend where Gangneung recorded its first tropical night [1].
Despite the cool start, midday temperatures will rise sharply under the influence of a high-pressure system [1]. Seoul is expected to reach approximately 30 °C, while Daegu may hit 32 °C [1]. Meteorologists said strong sunshine will lead to high UV and ozone concentrations throughout the day [1].
While much of the country experiences heat, Jeju Island faces different conditions. Forecasts indicate the island will receive heavy and strong rain [1]. This localized precipitation contrasts with the clear, sunny skies dominating the mainland [1].
Residents are advised to prepare for the wide temperature gap between the morning and afternoon. The combination of high heat and UV levels suggests a need for sun protection, and hydration as the summer season officially begins [1].
“Seoul is expected to reach approximately 30 °C, while Daegu may hit 32 °C”
The stark contrast between cool mornings and hot afternoons, combined with localized heavy rain in Jeju, illustrates the instability typical of the early summer transition in East Asia. The emergence of the first tropical night in Gangneung suggests an accelerating warming trend that may lead to more frequent heatwaves across the peninsula.
