In San Miguel Santa Flor, Mexico, awareness of the UV Index is crucial for protecting your skin and overall health. The UV Index serves as a guide to understanding the risks of sun exposure throughout the day, helping you take proactive steps against sunburn and long-term skin damage. Given the region's Cwb climate—characterized by mild temperatures and moderate sunny days—it's essential to recognize peak UV levels, particularly between 11:00 AM and 2:00 PM, when readings can soar to a striking 14. By staying informed and adjusting your sun exposure accordingly, you can enjoy the beautiful outdoors without compromising your skin's health.
The UV Index shows a striking pattern as the day unfolds, starting from a low of 1 at 07:00 and 08:00. As the sun rises higher, it gains intensity, peaking at 12:00 with a significant 12. The afternoon brings the highest levels, reaching a robust 14 at both 13:00 and 14:00, suggesting it's crucial to take precautions during these hours. The intensity then gradually declines, dwindling to 8 by 16:00, falling to 5 at 17:00, and returning to a mild 1 by 19:00. This data underscores the importance of sun safety in the midday hours, where exposure can be dangerous without protective measures.
