Understanding the UV Index is crucial for residents of Gales Ferry, United States, as it provides valuable information about the intensity of ultraviolet radiation from the sun. Being aware of UV levels is key to preventing sunburn and protecting skin health, especially during the summer months when exposure can peak dramatically. With Gales Ferry's Cfb climate, characterized by mild summers, the UV Index can reach significant levels—climbing as high as 9 during midday hours.
