Understanding the UV Index is crucial for residents and visitors in Los Angeles, Mexico, where the sun can be both rejuvenating and harmful. Being aware of UV levels helps prevent sunburn and contributes to long-term skin health, ensuring you enjoy the sunny climate without the risk of damage. In this region, characterized by a BSh climate, UV levels can soar—peaking at 12 between 1 PM and 2 PM—making it essential to stay informed about daily fluctuations. By monitoring the UV Index, you can take effective precautions and make the most of your time outdoors.
As the sun rises, the UV Index slowly climbs, starting at a low 1 at 07:00 and 08:00. By 09:00, it slightly increases to 2. However, the real intensity kicks in as the day progresses, peaking at an impressive 12 between 13:00 and 14:00. This is the critical time when sun protection is essential, given the dangerous exposure level. As the afternoon wanes, the index starts to decrease, dropping to 10 by 15:00 and further declining to 5 at 17:00. Finally, as the sun sets, it returns to a mild 1 by 19:00. Take note of these fluctuations, as they are crucial for staying safe under the sun!
