In Tumba, China, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding UV levels not only helps in preventing sunburns but also plays a vital role in safeguarding against long-term skin damage. Tumba's climate, characterized by its Dwc classification, exposes residents to high UV levels, particularly during midday when the index peaks at a scorching 14. With this in mind, it's essential to stay informed about the UV Index and take appropriate precautions, ensuring that your time outdoors is both enjoyable and safe.
The UV Index throughout the day presents a dynamic picture of sun intensity, peaking at a critical 14 between 1:00 PM and 2:00 PM.

As the sun rises higher, it reaches a robust 10 at 11:00 AM and culminates at a sizzling 13 at noon. The late afternoon sees a slight decline, dropping to 11 by 3:00 PM, before tapering down to 2 by 6:00 PM and returning to a restful 1 by 7:00 PM. For those venturing outdoors, the hours from 11:00 AM to 3:00 PM clearly underscore the importance of sun protection!

As the UV Index varies throughout the year, it’s critical for both visitors and residents to understand seasonal changes and high-risk months. From January (UV Index 4) to December (UV Index 4), the UV levels rise sharply, peaking during the summer months. March shows a significant increase to a UV Index of 9, which is classified as very high, while April through August reach extreme levels with indices ranging from 12 to 14, indicating a burn time as short as 10 minutes. High-risk months include March through September, where protective measures, such as wearing sunscreen, hats, and UV-protective clothing, are essential to prevent skin damage. As we transition into the fall and winter months, UV exposure decreases, allowing for more leisurely outdoor activities without the immediate risk associated with extreme UV radiation. Always stay informed and take necessary precautions during high UV periods to ensure safety.
