Understanding the UV Index is crucial for everyone living in or visiting La Romana, Spain, where sunny days are the norm, thanks to its BSk climate. High UV levels can significantly increase the risk of sunburn and long-term skin damage; thus, being aware of the daily index helps you take necessary precautions.
