Understanding the UV Index is crucial for residents of Bilariaganj, India, where the climate is characterized by hot summers and moderate rainfall. With peak UV levels reaching as high as 12 around midday, awareness of UV exposure is essential for sunburn prevention and maintaining skin health. As locals enjoy the outdoors, being mindful of these UV levels can help safeguard against harmful effects, making it important to incorporate protective measures, especially during the most intense hours of sunlight.

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.
