In Lushan, China, being aware of the UV Index is crucial for maintaining skin health and preventing sunburn, especially given the region's Cfa climate, characterized by warm summers and ample sunlight. Understanding UV levels throughout the day empowers residents and visitors to take appropriate precautions, as the UV Index can peak at a concerning 13 around midday, indicating a very high risk of harm from unprotected sun exposure. By knowing when the UV risks are greatest, you can enjoy the beautiful outdoor scenery without compromising your skin's health.
The UV Index undergoes a notable progression throughout the day, beginning at a gentle 1 at 07:00, before gradually rising to a moderate 2 by 08:00.

With this data in mind, it's crucial to enjoy the outdoors safely, particularly between 11:00 and 14:00, when the sun's rays are at their most intense.

The UV Index exhibits notable seasonal changes, peaking during the summer months. From January to February, UV exposure increases from high to very high, with a significant jump in March, reaching extreme levels that persist through September. The highest risk occurs from July to August, when the UV Index hits 14.
