Awareness of the UV Index is essential for residents and visitors of Gujeong, South Korea, where the Dfb climate brings both vibrant summers and harsh sun exposure. Understanding UV levels is crucial for sunburn prevention and safeguarding skin health, especially during peak hours between 10 AM and 2 PM, when the UV Index can reach as high as 10. With typical exposures presenting significant risks, knowing when to seek shade or apply sunscreen can make a dramatic difference in protecting your skin and enjoying the beautiful outdoor environment that Gujeong has to offer.
The UV Index throughout the day paints a vivid picture of sun intensity. Starting at a mild 1 at 7:00 AM, the index gradually climbs, reaching a more noticeable 3 by 8:00 AM. The real surge occurs between 9:00 AM and 12:00 PM, where it peaks at 10—a crucial time for sun protection. After that, it begins to gently decline, with 9 at 1:00 PM, 8 at 2:00 PM, and dropping further to 6 by 3:00 PM. As the sun starts its descent, the index sees a steady fall, ending at a comfortable 1 by 6:00 PM, making the later hours much safer for outdoor activities. Pay attention to the height of UV levels around midday for optimal sun safety!
