Understanding the UV Index in El Zulia, Colombia, is crucial for safeguarding 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 when exposure is too high. With a tropical climate characterized by intense sunlight, El Zulia experiences peak UV levels that often reach dangerous highs—especially during midday hours when values climb above 10. By being aware of the daily UV Index, residents and visitors can take essential precautions, ensuring they enjoy the warm weather while minimizing harmful effects on their skin. Stay informed and protect yourself from the sun’s powerful rays!
The UV Index today offers a clear picture of solar intensity throughout the day, peaking dramatically as the sun rises higher in the sky. Starting from a mild 1 at 07:00, the index quickly climbs to 4 by 08:00 and sharply escalates to 10 by 10:00. The midday sun reigns supreme, reaching its pinnacle at 13 by 12:00, and maintaining a robust score of 12 until 13:00. As the afternoon progresses, the intensity steadily declines, dipping to 5 at 15:00, and tapering off to 1 by 17:00. As the sun sets, the UV Index drops to 0 by 19:00, making it a day where sun safety is paramount during those peak hours, particularly between 10:00 and 14:00, when the sun's rays are at their most potent.
