In Shanhe, China, being aware of the UV Index is crucial for maintaining healthy skin and preventing sunburn, especially during the peak sunlight hours when UV levels can reach alarming heights. Understanding UV levels helps residents and visitors alike protect themselves from the harmful effects of excessive sun exposure, which is particularly important in a Dwa climate like Shanhe’s, where summers can bring intense sunlight. With UV Index readings soaring to a maximum of 12 around noon, it's essential to stay informed and take necessary precautions to enjoy the sun safely.
As the sun rises, the UV Index begins at a low 1 at 07:00, prompting a gentle warming of the day.

Throughout the year, the UV Index displays significant seasonal variations, indicating changing levels of sun exposure. January and February show moderate UV levels (4 and 5, respectively), where a burn can occur in as little as 30 minutes. As spring approaches, March and April see a sharp increase, with indices of 8 and 9 marking very high levels and reducing burn times to just 15 minutes. The intensity peaks in May, June, July, and August, where the UV Index reaches extreme levels of 12 and 11, requiring protective measures due to a quick 10-minute burn time. In September and October, while the UV levels drop to very high levels (10 and 8), it’s still crucial to remain vigilant with a return to a 15-minute burn time. As winter arrives, November and December revert to moderate levels (5 and 3), allowing for longer burn times of 30 minutes. Visitors and residents should prioritize sun protection, especially during the high-risk months of March through October, to mitigate the risk of skin damage and promote safe outdoor activities.
