Understanding the UV Index in Changhe, China, is crucial for safeguarding your skin and overall health. Being aware of UV levels helps you take proactive measures against sunburn and long-term skin damage, especially during the peak periods of UV exposure. In Changhe's humid subtropical climate, typical UV Index levels can rise dramatically, reaching a maximum of 11 during midday hours. This means that when the sun is at its highest, the risks increase significantly, making it essential to stay informed and protect yourself accordingly. Whether you’re enjoying outdoor activities or leisurely strolls, knowing the UV Index can help ensure a sun-safe experience in this vibrant city.
The UV Index throughout the day presents a dynamic picture of sun exposure. As early as 7:00 AM, the index starts at a mild 2, ramping up to a moderate 4 by 8:00 AM. The sun's intensity peaks around 11:00 AM and 12:00 PM with a striking 11, marking the height of caution for outdoor activities. As we move into the afternoon, the index gradually declines, dropping to 8 by 2:00 PM and further to 5 by 3:00 PM. The evening brings relief, with the UV Index decreasing to a 1 by 5:00 PM and finally hitting 0 by 7:00 PM. It’s clear that the midday hours pose the greatest risk, so sun safety measures are essential during those peak times.
