Understanding the UV Index is crucial for residents of San Fernando, Philippines, where the tropical climate often exposes the community to high levels of ultraviolet radiation. Awareness of the UV Index helps in preventing sunburn and maintaining long-term skin health, especially during peak hours when the index can soar to a concerning level of 14.
