My conclusion on the optimal travel time for Hawaii
The island state of Hawaii is a year-round destination for people from all over the world. The best months for traveling are May to October in the summertime, as it rains less here. However, the months of July and August are also the main travel season for Hawaii, as summer holidays are in the USA. The beaches are more full and the trips more expensive. Popular travel months for Europeans who want to escape the frosty winter in this country are the winter months of November, December and January. Especially during the Christmas holidays the prices for hotels and flights to Hawaii rise immensely. If you want to fly cheaply to the island state, the months from mid-April to June as well as September and October are the best. The weather in Hawaii is perfect for a holiday all year round anyway!
