Understanding the UV Index is essential for residents of Hamren, India, especially given the region's distinct Cwa climate that brings warm summers and significant sun exposure. The UV levels can peak remarkably high—reaching an extreme of 13 at midday—making awareness vital for preventing sunburn and maintaining healthy skin. With the potential risks associated with intense UV radiation, knowing the daily fluctuations is crucial for planning outdoor activities safely. As you enjoy the beautiful landscapes of Hamren, keep an eye on the UV Index to ensure your time in the sun is both enjoyable and safe!
As the sun rises, the UV Index makes a steady climb, starting at a modest 4 by 7:00 AM. By 8:00 AM, it spikes to 7, signaling a day of increasing solar intensity. As the clock strikes 9:00 AM, the UV Index peaks at a striking 11, reaching its zenith with 13 at both 10:00 AM and 11:00 AM—a clear warning that midday sun can be relentless. The intensity gradually wanes thereafter, dropping to 12 at noon and sliding to 9 by 1:00 PM. As the afternoon progresses, the UV Index cools down to 6 at 2:00 PM, and further down to 3 by 3:00 PM. By the time the sun begins to set, the UV radiation diminishes to 1 at both 4:00 PM and 5:00 PM, before finally reaching 0 by 6:00 PM, signaling a much safer environment as evening falls. Remember to protect your skin during those peak hours!

High-risk months include March through September, where the UV Index peaks at 13 in July, categorizing it within the extreme exposure category.
