Understanding the UV Index is crucial for residents of Rajshahi, Bangladesh, where the sun’s intensity can pose serious risks to skin health. As the climate here falls within the Aw zone, the region experiences significant UV exposure, especially during peak hours. Monitoring UV levels is vital not just for sunburn prevention, but also for safeguarding long-term skin health. With indices often soaring to 12 around midday, it’s essential for the community to stay informed and take necessary precautions to enjoy the beautiful sunny days without compromising their well-being.
The UV Index reveals a dramatic peak in sun intensity throughout the day. Early risers will notice moderate levels starting at 07:00 with a UV Index of 3, but things heat up quickly. By 10:00, the Index skyrockets to 11, signaling very high exposure. The sun reaches its zenith at 11:00, where the Index reaches its maximum of 12, urging caution for those outdoors. As the afternoon progresses, the intensity begins to taper off, dropping to 9 by 13:00 and steadily decreasing to 6 at 14:00. By 16:00, it falls to 1, and by dusk, the UV threat diminishes entirely, with readings of 0 from 18:00 onward. For sunseekers and those planning outdoor activities, the morning to early afternoon is when a protective approach is crucial.
