Understanding the UV Index is crucial for anyone living in or visiting San Andres, Puerto Rico. The index provides essential information about the intensity of ultraviolet radiation, helping you gauge the risk of sunburn and protect your skin health. With a warm climate characterized by high UV exposure, particularly between 10 AM and 2 PM, it's vital to be proactive about sun safety. On sunny days, UV levels can soar as high as 15, making it essential to plan your outdoor activities accordingly to avoid damaging effects. Stay informed and enjoy the beautiful sun without compromising your skin!
The UV Index today paints a striking picture of sun intensity throughout the day. Starting off gently at 1 at both 7:00 AM and 8:00 AM, the sun begins to escalate its strength, reaching a moderate 4 by 9:00 AM. As the day unfolds, the index skyrockets to 11 by 11:00 AM and peaks at a scorching 15 between 1:00 PM and 2:00 PM. Fortunately, the intensity wanes in the afternoon, dropping to 4 by 5:00 PM, before tapering off back to 1 after 6:00 PM. This pattern emphasizes the importance of sun safety, especially during peak hours when UV exposure is at its highest. Be sure to take precautions and enjoy the sun wisely!
