Understanding the UV Index is vital for the residents of Utan, Indonesia, where the tropical climate can lead to varying levels of sun exposure throughout the day. With UV levels peaking at a dangerous 10 during midday, it's crucial to be aware of these numbers to effectively prevent sunburn and protect your skin health. This awareness not only helps minimize the risk of immediate discomfort from sun exposure but also safeguards against long-term skin damage. Given Utan’s warm and sunny environment, knowing when to seek shade or apply sunscreen can make all the difference in enjoying the outdoors safely. Stay informed and shield yourself against the sun’s harmful rays!
The UV Index offers a glimpse into the sun's intensity throughout the day. At 07:00, it starts gently with a reading of 1, gradually climbing to 2 by 08:00. As the sun rises higher, the index peaks at an impressive 10 at 12:00, indicating the most potent rays. It slightly eases to 9 at 13:00 and then descends further to 7 at 14:00, before falling to 5 by 15:00. The late afternoon brings a significant drop, with the index retreating to 2 at 16:00 and dwindling to 1 by 17:00. By 18:00 and 19:00, the UV Index returns to 0, signaling the end of the sun's peak intensity for the day. Be sure to protect your skin during those midday hours when the sun is strongest!
