In Encrucijada 3ra. Seccion (Las Calzadas), understanding the UV Index is vital for protecting your skin and overall health. With peak UV levels reaching 14 during midday, awareness is key to preventing sunburns and reducing the risk of skin cancer. The region's tropical climate can lead to increased sun exposure throughout the year, making it essential to check UV levels regularly and take appropriate precautions. By staying informed about the UV Index, residents and visitors alike can enjoy the sunshine safely while minimizing potential harm to their skin.
The UV Index throughout the day starts off gently, with maximum values of 1 at 7:00 and 8:00, suggesting a safe time for those sensitive to sunlight. As the sun rises higher, the index escalates rapidly, peaking at 14 around 1:00 PM—a cautionary signal for outdoor activities. The intensity slightly dips afterwards, with values maintaining around 10 to 13 from 11:00 to 14:00, before gradually descending in the afternoon. By 5:00 PM, the index lowers to 4, offering a more manageable environment once again. As evening approaches, the UV index returns to a minimal 1 by 7:00 PM, marking the end of a day characterized by a significant solar intensity and the need for sun protection during peak hours.
