In Yanggu, South Korea, being aware of the UV Index is crucial for maintaining optimal skin health throughout the year. With peak UV levels reaching as high as 11 during midday, understanding these levels can help residents and visitors alike take essential precautions against sunburn and long-term skin damage. The region's Dwa climate typically brings a mix of sunny days and variable weather patterns, which can influence UV exposure risks. Staying informed about the UV Index not only safeguards your skin but also enhances your overall outdoor experience in this beautiful area.
The UV Index throughout the day demonstrates a significant rise as the sun reaches its zenith. Starting from a mild 1 at 07:00, the intensity escalates rapidly, hitting 3 by 08:00 and climbing to a peak of 11 at 12:00—the moment when sun protection is imperative. As the afternoon progresses, the index gradually declines, showing values of 10 at 13:00, 9 at 14:00, and 7 at 15:00. By 16:00, it drops to 4, and by the evening, the UV exposure wanes, returning to 1 by 18:00 and 19:00. This pattern underscores the importance of vigilance during midday hours when UV radiation poses the highest risk. Remember to stay shaded and apply sunscreen generously!

Visitors and residents are strongly advised to take precautions during these months by wearing protective clothing, applying sunscreen frequently, and seeking shade during peak sunlight hours.
