Understanding the UV Index is crucial for residents and visitors in General Simon Bolivar, Mexico, particularly given its warm, dry climate classified as BWh. With peak UV levels reaching dangerously high values—an index of 13—awareness is essential to prevent painful sunburns and long-term skin damage.
