Understanding the UV Index is crucial for residents of Lidong, China, especially given the region's Dwb climate that can lead to higher levels of sun exposure. Being aware of UV levels helps prevent sunburn and protects your skin health, making it essential to check daily UV forecasts. With early morning readings peaking at 7 around midday, the risks of harmful UV radiation increase significantly, warranting caution. Stay informed to enjoy the beautiful sunny days while safeguarding your skin from potential damage!
During a sun-drenched day, the UV Index peaks between 10:00 AM and 12:00 PM, hitting a maximum of 7, which signals a high risk of harm from unprotected sun exposure. As the morning unfolds, the index climbs steadily: starting at 3 at 7:00 AM, it reaches 4 by 8:00 AM and further escalates to 6 by 9:00 AM. From there, the index holds steady at 7 through the late morning hours. However, as the afternoon progresses, the UV levels begin to decline, dropping to 6 at 1:00 PM and gradually descending to 3 by 3:00 PM. By 4:00 PM, the UV Index falls to 2, and as the day wanes into the evening, it dwindles to 1 by 5:00 PM, ultimately hitting 0 after 7:00 PM. To stay safe, remember to seek shade and apply sunscreen during those peak hours!

Throughout the year, the UV Index displays significant seasonal changes that influence sun exposure risk. From January to April, the UV Index gradually increases from a low of 2 in January to a high of 6 in April, transitioning from minimal risk to high-risk levels. The summer months of May, June, July, and August pose the greatest hazard, with UV Index values peaking at 10 in July and requiring only 15 minutes of sun exposure before burns can occur. September marks a decline to high levels again (UV Index 6), while October sees a shift back to moderate exposure. The low-risk months return in November (UV Index 2) and December (UV Index 1), allowing for safer outdoor activities. It is crucial for visitors and residents to exercise caution during May to August, employing protective measures such as sunscreen, hats, and sunglasses to mitigate potential harm from UV rays.
