In Zapotan, Mexico, awareness of the UV Index is crucial for maintaining skin health and preventing sunburn, especially given its Csa climate, characterized by warm summers and mild winters. Understanding UV levels helps residents and visitors alike take appropriate precautions against harmful solar radiation, particularly during peak hours when the index can surge to a striking 12. With midday exposure carrying the highest risk, it's important to stay informed and protected—because a little knowledge today can safeguard your skin for years to come.
As the day unfolds, the UV Index rises steadily, beginning at a safe 0 at 07:00 and peaking dramatically. By 10:00, it escalates to 4, signaling the need for some sun protection. The intensity reaches 10 at 12:00, and then hits its maximum at 13:00 with a formidable 12. Right after, it slightly dips but remains high at 12 until 15:00. As the afternoon wanes, the UV Index begins to decline, dropping to 9 by 16:00, and continuing its descent to 1 by 19:00. This fluctuation highlights the importance of being sun-smart during peak hours, especially between 11:00 and 15:00, when the sun is at its strongest.

The UV Index exhibits significant seasonal fluctuations, with the highest levels typically occurring from March to October, when exposure is classified as extreme for most months. April holds the peak UV Index at 14, resulting in a minimal burn time of just 10 minutes. The months of January and February also present high risk, characterized by very high indices of 8 and 10, respectively, where a burn can occur in as little as 15 minutes. Visitors and residents should take precautions, especially during March through October, by wearing protective clothing, applying sunscreen, and seeking shade to mitigate the risks of overexposure. As the UV Index drops in November and December, with values of 9 and 7, the risk decreases, allowing for safer outdoor activities with longer burn times of 15 and 25 minutes. Overall, awareness of these seasonal changes is crucial for health and safety during outdoor activities.
