Understanding the UV Index is crucial for residents and visitors in Hamhung, North Korea, where the climate can enhance sun exposure risks. With average UV levels peaking at 11 during midday, awareness of these levels is essential for preventing sunburn and protecting your skin health. Hamhung's Dwb climate signifies distinct seasonal changes, yet when the sun shines brightly, the potential for harmful UV radiation increases. Take note of the daily UV Index to ensure you enjoy the sun safely and effectively.
The UV Index shows a dramatic rise as the sun climbs in the sky, peaking at 11 between noon and 1 PM, indicating an exceptionally high risk of harm from unprotected sun exposure.

As it reaches 10 at 11 AM, it signals to outdoor enthusiasts to seek shade or don protective gear. The index begins to wane after 1 PM, dropping to 10 at 2 PM, and declining further to 3 by 5 PM, before settling back to 1 after 6 PM. To stay safe under the scorching sun, be sure to take precautions during those peak hours!
