Understanding the UV Index is crucial for residents of Kokrajhar, India, as it plays a vital role in protecting skin health and preventing sunburn. With the region's Cwa climate, characterized by hot summers and a pronounced rainy season, awareness of UV levels becomes more significant, especially during the peak hours when the index can soar to 11. This highlights the importance of taking appropriate precautions, such as using sunscreen and seeking shade, to minimize exposure during the highest UV radiation times. By staying informed about local UV conditions, you can enjoy the sun safely while safeguarding your skin from its harmful effects.
The UV Index throughout the day showcases a peak that highlights the intensity of sun exposure. Starting at a moderate 4 by 07:00, the index climbs steadily, reaching its zenith of 11 at 10:00, 11:00, and 12:00—a crucial window for sun safety. After the midday sun, the index begins to decline sharply, dropping to 8 by 13:00, then tapering off further to 6 at 14:00. By the late afternoon, it plummets to 3 at 15:00 and descends to 1 by 16:00 and 17:00. The UV exposure reduces to 0 after 18:00, signaling a retreat of sun strength as evening approaches. It’s essential to stay vigilant during those peak hours for maximum sun protection!
