Hubby and I were in Hawaii in 1975, in August. It depends, really where you go. If you go to the big island, then you have to go see the volcanoes. Believe it or not, it is very cold up in the mountains. It rained nearly every morning for a few hours, but the afternoons and evenings were perfect. Do you know which islands you'll visit? We visited Oahu, Hawaii, Maui, and Kauai......all gorgeous, but each one has different things to offer. There is a magnificent canyon on Kauai, they call it the Grand Canyon of Hawaii. Maui has wonderful beaches and Hawaii has the volcanoes and spectacular scenery. Oahu has the most to do, what with Pearl Harbor, capitol building, Polynesian Culture Center, Waikiki Beach, etc. You'll have a great time..............42
