Awareness of the UV Index is crucial for residents and visitors in Yushu, China, where the sun's rays can pose significant health risks. Understanding UV levels helps to prevent sunburn and promotes overall skin health, allowing you to enjoy the stunning landscapes without compromise. Yushu, with its Dwa climate characterized by high altitudes and strong sunlight, sees UV Index levels peak at 10 around midday, indicating a need for proactive sun safety measures. By staying informed about the UV Index, you can better protect yourself and make informed choices about outdoor activities throughout the day.
The UV Index throughout the day reveals a dynamic pattern of sun intensity, peaking dramatically as the sun climbs. At 07:00, it starts at a mild 2, but by 09:00, it escalates to a notable 7. The intensity reaches its zenith at 11:00 and 12:00, both with a robust 10, demanding protective measures for outdoor activities. As the afternoon progresses, the index gradually declines, falling to 5 by 15:00 and tapering off to 1 by 17:00, where it remains until twilight. This highlights the critical hours for sun exposure, especially between 10:00 and 14:00, when the sun’s rays are at their strongest.
