Understanding the UV Index is crucial for residents and visitors in Haean, South Korea, where sunny days invite outdoor activities but also pose risks to skin health. With UV levels peaking at 11 around noon, awareness of these fluctuations helps prevent sunburn and long-term skin damage. Haean's temperate Dfb climate means varying UV intensity throughout the day, making it essential to stay informed about daily UV exposure risks.

This dynamic progression urges outdoor enthusiasts to take precautions during the peak hours, especially between 10:00 and 13:00, when the index poses a strong risk for unprotected skin.
