Hawaii is best known for its beaches, flowers, palm trees, waterfalls, luaus, and tropical islands. Hawaii is the 19th most visited state! The weather is very dry from April to October. The weather, recently (February), has been in the high 60s and low 70s. In July it is 73 to 87 degrees. Hawaii only has two seasons, winter and summer.
I would take shorts, T-shirts, and bathing suits. I think the beaches will be beautiful and it will be very relaxing. I also think I might try snorkeling. I want to see some of the reef, too. I can't wait to stay in the tropical resorts!
