Understanding the UV Index in Tianyi, China, is crucial for protecting your skin and overall health. With a climate characterized by warm summers and cold winters (Dwb), the UV exposure can vary significantly throughout the year, peaking typically at midday. Awareness of UV levels helps in preventing sunburn and minimizing long-term skin damage. For example, around midday, the UV Index can reach as high as 9, indicating an increased risk of harm from unprotected sun exposure. By staying informed about daily fluctuations in UV readings—like those peaking from 11:00 AM to 1:00 PM—residents and visitors alike can take the necessary precautions to enjoy the sun safely in this vibrant region.
As the sun rises, the UV Index begins to climb, reaching a maximum of 9 between 11:00 AM and 1:00 PM—the peak time for sun exposure. Starting at a modest 2 at 7:00 AM, the index steadily ascends to 4 by 8:00 AM, hitting 6 by 9:00 AM. The day's intensity culminates at noon, remaining at that level until 1:00 PM before gradually tapering off.
