In Mattanur, India, understanding the UV Index is crucial for protecting your skin and overall health. The UV Index measures the strength of ultraviolet radiation from the sun, which can lead to sunburn and long-term skin damage if not monitored. With Mattanur's tropical climate, residents are exposed to varying UV levels throughout the day, peaking at a serious UV Index of 13 around noon. Being aware of these levels not only helps in taking necessary precautions but also encourages a healthier lifestyle by fostering sun safety practices. Stay informed, stay protected!
The UV Index throughout the day presents a clear picture of sun intensity, peaking sharply at 12:00 PM with a noteworthy index of 13, signaling a strong need for sun protection during this period. As the sun rises, the index climbs from a mere 1 at 7:00 AM to an alerting 10 by 10:00 AM.
