Staying aware of the UV Index is crucial for residents in Fraccionamiento Real Palmas, Mexico, where the BSh climate exposes inhabitants to heightened levels of ultraviolet radiation. Understanding UV levels is essential not only for preventing sunburns but also for protecting long-term skin health; with peak indexes reaching as high as 12 between noon and 2 PM, the risk during these hours is significant.
