Understanding the UV Index is crucial for residents of Bilariaganj, India, where the Cwa climate brings distinct seasonal variations and elevated sun exposure. With UV levels peaking at 9 during midday hours, awareness of these levels plays a vital role in preventing sunburn and ensuring long-term skin health. Knowing when UV radiation is at its highest can help you take necessary precautions and enjoy the outdoors safely, minimizing the risk associated with excessive sun exposure. Embrace the sunshine wisely by staying informed on the UV Index—your skin will thank you!
As the sun rises, the UV Index begins its ascent, peaking at 11:00 AM and 12:00 PM with a blistering 9. The day starts gently, with 07:00 AM registering a modest 2, but by 09:00 AM, it climbs to a moderate 6. The intensity escalates, hitting 8 at 10:00 AM and reaching its zenith shortly after noon.

As the seasons change, so too does the UV Index, which indicates the strength of ultraviolet radiation. January and December experience moderate UV levels (Index 5), advising a burn time of 30 minutes. However, February marks a shift to high exposure levels (Index 6), reducing burn time to 25 minutes. The spring months, particularly March and April, indicate a significant rise in UV levels, reaching very high (Index 9 and 10) and requiring only 15 minutes of exposure before burning. The peak of summer from July to August sees the highest UV Index levels, classified as extreme (Index 11-12), with a minimal safe exposure time of just 10 minutes. Visitors and residents should be particularly cautious during these high-risk months and take protective measures such as sunscreen and clothing to limit UV exposure. As autumn arrives, UV levels decrease but remain significant, with September to October maintaining a very high classification. Finally, November again falls back to high levels, prompting continued awareness of sun safety even as temperatures cool.
