Understanding the UV Index in Gueines, Cuba is essential for protecting your skin from harmful ultraviolet radiation, especially in this tropical climate known for its warm, sunny days. The UV Index provides crucial information on how intense the sun's rays are at different times of the day, helping you gauge the risk of overexposure. With UV levels peaking at 13 between 12:00 PM and 2:00 PM, awareness of these numbers is vital for sunburn prevention and promoting overall skin health. By monitoring the UV Index, you can enjoy the beautiful Cuban sun safely, ensuring your time outdoors remains pleasant without compromising your skin's well-being.
