What are the differences between Waikiki Beach in Hawaii and the beach Persse knows in Connemara, Ireland?

It is very hot in Hawaii, and even the ocean water feels like warm milk and is cloudy as well. The sand is coarse and yielding and is full of people and noises. In contrast, the beach in Connemara has firm, damp sand and bracingly cold, clear water, and it is quiet except for the sound of the surf and the birds.
