Understanding the UV Index is crucial for the health and safety of residents in Jalalabad, India, where the sun's rays can be particularly intense. With UV levels peaking around noon, awareness of these indices is essential to prevent sunburn and protect skin health. The region typically experiences a Cwa climate, characterized by hot summers, making it vital to monitor UV exposure, especially during the high-risk hours from 10 AM to 2 PM, when the UV Index can soar to 11. Equip yourself with the knowledge to enjoy the sun safely while minimizing harmful effects!
The ultraviolet (UV) index throughout the day reveals a dynamic pattern of sun intensity. Starting at 07:00, the UV index is a modest 2, indicating the sun is just beginning to gain strength. As the morning progresses, it climbs steadily to 4 by 08:00 and reaches a notable 6 at 09:00, signaling a push towards peak hours. At 10:00, the intensity peaks at 9, and by 11:00 and 12:00, it hits a maximum of 11, marking the sun’s strongest exposure. Though the afternoon remains considerable, the index declines to 10 at 13:00 before dropping to 7 by 14:00. As the day winds down, the UV index falls sharply to 4 at 15:00, and later to 2 by 16:00, concluding with softening values of 1 at 17:00 and 18:00, and finally settling at 0 by 19:00. This hourly progression underscores the importance of sun safety during midday hours when UV levels are at their peak.

The high-risk months are typically June, July, and August, when the UV Index peaks at 11-12 and the burn time decreases to just 10 minutes. As spring approaches, UV levels begin to climb, reaching very high levels by March, and remaining extreme through the summer. Visitors and residents should take precautions during these months, such as wearing protective clothing, applying sunscreen regularly, and seeking shade, especially during midday hours to reduce the risk of skin damage.
