Understanding the UV Index in A Coruña, Spain is crucial for protecting your skin and overall health. With high levels of ultraviolet radiation peaking around midday, awareness of these levels can help prevent sunburn and long-term skin damage.

By staying informed about the UV Index, you can enjoy the beautiful beaches and outdoor activities this vibrant city has to offer, all while safeguarding your skin health.
