In Jingchuan Chengguanzhen, understanding the UV Index is crucial for safeguarding your skin against harmful ultraviolet rays. With peak UV levels reaching as high as 11 during midday hours, awareness of these fluctuations is vital for effective sunburn prevention and long-term skin health. The region's Dwa climate not only exposes residents to significant UV radiation but also presents unique challenges throughout the seasons. Stay informed about UV levels to enjoy the outdoors safely, protecting yourself and your loved ones from the potential dangers of overexposure.
At dawn, the UV Index starts at a gentle 1 by 07:00, indicating minimal exposure risk. As the sun climbs higher, the intensity rises sharply, reaching a maximum of 11 between 12:00 and 13:00—a time when protective measures are crucial. The peak UV Index highlights the importance of sun safety, as conditions can be particularly harsh. The afternoon sees a gradual decline, dipping to 8 by 15:00 and further decreasing to 3 by 17:00. As evening approaches, the index wanes to a mellow 1 by 19:00, suggesting a return to safer exposure levels. Keep in mind that tracking the UV Index throughout the day can help protect your skin from harmful rays!

Throughout the year, the UV Index exhibits significant seasonal changes, reaching its peak during the summer months. From January to February, the UV levels are moderate (4 to 5), with a burn time of 30 minutes. However, as we transition into March with a high index of 7, burn time decreases to 25 minutes. The risk escalates sharply in April and peaks in May and June, with indices of 9 to 12 and burn times plummeting to just 10 minutes in extreme conditions. July and August maintain these elevated levels before dropping slightly in September to 10, followed by October at 8. The year closes with moderations in November (UV 5) and December (UV 3), both allowing for longer exposure times again at 30 minutes. Visitors and residents are strongly advised to take precautions from late March through October, particularly during May to August, where UV exposure is most intense. This includes wearing protective clothing, applying sunscreen regularly, and seeking shade during peak sunlight hours to minimize the risk of sunburn and long-term skin damage.
