In Bhojpur, Nepal, awareness of the UV Index is crucial for maintaining skin health and preventing sunburn, particularly as the region experiences varying levels of sun exposure throughout the day. Understanding UV levels is essential for safeguarding against the harmful effects of ultraviolet radiation, especially during peak hours when the UV Index hits a maximum of 13 around noon. Given Bhojpur’s Cwb climate, which combines warm summers and mild winters, residents and visitors alike should stay informed about daily UV risks to enjoy outdoor activities safely and protect their skin. Stay vigilant and always check the UV Index to ensure a healthy, sun-safe experience!
During the morning hours, the UV Index begins at a moderate level of 4 at 7:00 AM, quickly escalating to 7 by 8:00 AM as the sun gains intensity. The peak UV exposure occurs between 10:00 AM and 12:00 PM, reaching a high of 13 at 11:00 AM. It's essential to note that from 9:00 AM to 12:00 PM, the index stays dangerously elevated at 10 or higher, indicating a need for sun protection. As the afternoon progresses, the UV levels begin to decline, dropping to 11 at 1:00 PM, then significantly tapering off to 4 by 3:00 PM. The UV Index continues to decrease through the evening, reaching 1 by 5:00 PM, and eventually falling to 0 after 6:00 PM. Overall, it's crucial to take precautions during the midday hours when UV exposure is at its highest.

Throughout the year, seasonal UV changes reveal significant fluctuations in the UV Index, with the highest levels occurring from April to September, where the index reaches extremes of 11 to 14. The high-risk months include March through September, particularly April to August, when the exposure category is classified as extreme, leading to a notably short burn time of just 10 minutes during peak sun hours. Visitors and residents are advised to take necessary precautions during these months, including wearing sunscreen, donning protective clothing, and seeking shade to minimize skin damage. As the year progresses into October and November, while UV levels remain very high, the burn time increases slightly, providing a small reprieve. In contrast, December and January see a decline in UV levels, returning to moderate, yet even then, caution is still warranted.
