From the weather, the island you want to visit, activities you want to do during your trip and major festivals scheduled, to best accommodations for you and your companions and convenient transportation costs, there are a lot of things to account for before planning Hawaii vacations.
With so many aspects to consider, it is no wonder that many tourists have a hard time deciding on the best time to plan a trip to Hawaii. The good news for you is that the weather of Hawaii is fairly decent throughout the year, so this is not a major aspect to be concerned about.
Since the weather is reliable, the only thing you should focus on is deciding what you want to do and see while in Hawaii. Nonetheless, it is necessary to mention that returning visitors should consider visiting the islands in another season, as they have a slightly new look at different times of the year.
During the rainy season, which lasts from November to March, you will have the opportunity to see the humpback whales. Even though the whales stay near the Hawaiian coasts sometimes until early May, the best months to catch a glimpse of the spectacle is from January to early March.
However, even though you might be tempted to plan the trip during winter in order to escape the snow and cold weather of the mainland, you should know that you will not find cheap flights, lodging and bargains in general.
Consequentially, make sure you acquire a travel package within the Hawaiian dry season, which lasts from April to October. During this period of the year, you will have very few restrictions, especially regarding the water activities. Therefore, if you want to parasail, sail, scuba dive or do snorkeling, it is best to go in the summer and avoid the risks associated with the unpredictable currents and storms of winter.
