In El Mezquite Grande, Mexico, being aware of the UV Index is crucial for safeguarding your skin against harmful ultraviolet radiation. Understanding UV levels can play a significant role in preventing sunburns and promoting overall skin health, especially in a region with a Cwa climate that exposes residents and visitors to high UV radiation, particularly during midday hours. With peak UV Index values soaring to 13 between 1 PM and 2 PM, it's essential to take proactive steps to protect yourself from overexposure. Stay informed about the UV Index to enjoy the beautiful sunlight safely!
The UV index throughout the day reveals a dynamic pattern, starting from a low 0 at 7:00 AM and gradually climbing as the sun rises. By 10:00 AM, it reaches 4, signaling the start of potential sun sensitivity. As noon approaches, the intensity peaks dramatically at 12:00 PM with a UV index of 10, which is considered very high, urging outdoor enthusiasts to take protective measures. The afternoon hours continue to show significant UV levels, with a maximum of 13 at 1:00 PM and 2:00 PM, before slowly tapering off in the later afternoon and evening, dropping back to 1 by 7:00 PM. This data emphasizes the importance of sun safety, especially during the midday hours when UV exposure poses the greatest risk.

Throughout the year, the UV Index exhibits significant seasonal variations, peaking during the spring and summer months. From February through August, the UV Index consistently reaches extreme levels (11-14), with the highest values recorded in March, April, May, and August. Notably, October also remains at an extreme level (12), indicating potential for harmful UV exposure. The high-risk months for UV exposure are thus identified as February through August, where the advised burn time is only 10 minutes. In contrast, January, November, and December present lower UV levels (with indices of 9 and 8), classified as very high, allowing for a slightly longer exposure time of 15 minutes. Visitors and residents are strongly advised to take protective measures, such as wearing sunscreen, protective clothing, and seeking shade during peak UV hours, particularly from late winter through summer.
