Understanding the UV Index is crucial for residents of Gancheng, China, as it plays a vital role in protecting your skin and overall health. With peak levels soaring to 12 during mid-day, awareness of UV exposure can significantly aid in preventing sunburn and reducing long-term skin damage. Given Gancheng's semi-arid climate, its clear skies often translate to higher UV radiation, making it essential for locals to stay informed about daily UV levels. By mastering the UV Index, you can enjoy the sunny days while keeping your skin safe and healthy.
At sunrise, the UV Index begins its steady climb, starting at a safe 1 at 07:00. As the morning progresses, it escalates to 2 by 08:00 and reaches a pleasant 4 by 09:00. However, the real intensity hits between 10:00 and 13:00, with the UV Index peaking at a scorching 12 at 12:00, indicating a high risk of harm from unprotected sun exposure. As the afternoon unfolds, levels gradually descend, hitting 9 at 15:00 before tapering off to 4 by 17:00. By the evening hours, the index returns to a mild 1 by 19:00, reminding us of the importance of sunscreen amidst the sun's powerful midday rays.

Throughout the year, UV Index levels exhibit significant fluctuations, reflecting seasonal changes in sun exposure. From January to February, UV levels remain in the moderate range (4-5), with a burn time of 30 minutes. However, as spring approaches, March ushers in higher UV levels that peak in the summer months of May through August at an extreme level of 12, where the burn time dramatically reduces to just 10 minutes. Notably, March, April, May, June, July, and August are characterized as high-risk months due to their very high to extreme UV exposure.

As the year progresses into the fall months, UV levels gradually decrease, returning to moderate levels by November and December.
