Generally, you can find cheaper prices for flights and accommodations during the off-peak season which is typically from April to May and September to mid-December. However, keep in mind that prices may still fluctuate or be higher during holiday weekends or special events throughout these months.
To save even more money, consider visiting during weekdays instead of weekends, and avoid major holidays such as Christmas and New Year’s. Also, you can try out budget-friendly or free activities in Hawaii such as hiking, visiting public beaches and parks, and exploring local markets.
Ultimately, the key to finding the most affordable time to visit Oahu is to plan and be flexible with your travel dates.
Just make sure you do some research on flight and hotel prices during different seasons, and keep an eye out for deals and promotions. With a little bit of effort and flexibility, you can enjoy all that Oahu has to offer without breaking the bank.

Many tour operators in Hawaii offer whale-watching cruises during this time, where you can witness these majestic creatures up close in their natural habitat.

What Is Peak Tourist Season In Oahu?
If you’re asking yourself “What is peak tourist season in Hawaii?” it usually runs from mid-December through March, which is also the winter season, when visitors flock to the island to escape the cold weather in other parts of the world and enjoy the warm tropical climate of Hawaii.
It’s important to note that the peak season also coincides with the holiday season, which means that the island can get very crowded and prices for accommodations and activities can be significantly higher when compared to the off-season or shoulder months.
But despite the crowds, there are plenty of exciting activities, festivals, and celebratory days to enjoy during the peak tourist season in Oahu.
Visitors can experience the magic of the Honolulu City Lights, a month-long celebration featuring festive lights and holiday displays. They can also enjoy the Waimea Valley Audubon Center’s annual Hoʻokupu Hula No Lanakila celebration, which showcases the traditional hula dances and chants of Hawaii. For those who love the thrill of competition, the Vans Triple Crown of Surfing takes place during this time, featuring some of the world’s best surfers battling it out in some of Hawaii’s most famous waves.
We suggest all travelers plan if they’re visiting during the peak season to ensure that they can secure accommodations and activities that suit their preferences.
