What the Alaska water feels like in January

Water at this temperature is freezing cold, can cause pain and takes your breath away. Unless you are very experienced and are under strict supervision, swimming in this water for more than a few minutes can be very dangerous. Be careful, stay safe, and enjoy the rush of endorphins and exhilaration from a brief cold water swim.
