In Kishorganj, Bangladesh, awareness of the UV Index is crucial for safeguarding skin health against harmful sun exposure. Understanding UV levels not only helps in preventing sunburn but also plays a vital role in reducing the risk of long-term skin damage. With its Aw climate, Kishorganj experiences significant UV exposure, particularly during midday hours when the index peaks at 12. By staying informed about the UV Index, residents can take essential precautions to enjoy the sun while protecting their skin.
The UV Index provides a vital insight into sun exposure throughout the day, peaking during the late morning to early afternoon hours. At 07:00, it starts off low at 2, but by 08:00, it rises to 4, indicating increasing sun intensity. The real surge happens between 09:00 and 12:00, where it climbs dramatically to a maximum of 12 at 11:00 and 12:00. As the sun begins to dip after 13:00, the index gradually decreases to 11 at 1 PM and gently tapers off to 9 at 2 PM. By 3 PM, it continues to decline to 6, and by the evening, it reaches a minimal 1 at both 5 PM and 6 PM, finally falling to 0 by 7 PM. This hourly breakdown urges us to protect our skin during the peak hours, especially when the index hits its zenith.

As the seasons change, so do UV levels, significantly impacting sun exposure risk for both visitors and residents. January starts with a moderate UV Index at 5, with a burn time of 30 minutes. However, February ramps up to a high UV Index of 7 (25 min burn time), and by March and April, we reach very high levels at 8 and 9, respectively, reducing safe exposure to just 15 minutes. The peak months for UV exposure are May through August, where the Index surges to extreme levels (up to 13), necessitating caution with only 10 minutes of safe sun exposure. As the year progresses, September sees a slight decrease, but still remains at 12, followed by October with a very high UV of 10 (15 min burn time). Finally, the UV Index lowers to 8 in November and 6 in December, but caution is still advised. Visitors and residents should take protective measures—such as sunscreen, protective clothing, and seeking shade—especially during the high-risk months from March through September.
