Hawaii’s warm year-round weather and tropical climate are parts of what make it such a popular vacation destination. Visitors can enjoy lush rainforests, thundering waterfalls, and sunny beaches every month of the year. However, depending on what you’re looking to do, you might prefer to book during certain months.
the Best Time to Visit Hawaii
When is Hawaii at its most perfect for your favorite activities and interests? Here is a great guide for visitors to Hawaii, including a month-by-month weather breakdown.
Best Time for Whale Watching in Hawaii
Every winter, Humpback Whales return to the Hawaiian Islands from Alaska. They migrate to the warm, calm, shallow waters to breed and birth their calves. During this period, you can take a whale-watching cruise or simply look out at the water from the shore for the telltale waterspout or breaching of these incredible animals. The whale watching season lasts from November through May, with the best opportunities to see whales in January and February.
Best Time to Visit Hawaii to Avoid Crowds
If you want to time your trip to avoid crowds, you will want to travel to Hawaii during the so-called “shoulder season.” The golden periods when kids are in school, and there are no major holidays, can make it feel like you have the islands all to yourself. April, May, and the first week of June are typically quiet. In the fall, September through early December, excluding Thanksgiving, have thinner crowds.
Best Time for Swimming and Snorkeling in Hawaii
Summer is the best time to take a dip in the warm Hawaiian waters. The ocean temperature hovers around 82°, and the wind and surf are reliably low. Visitors of any experience level can enjoy snorkeling in the clear, calm summer sea.
Best Time to Cruise Hawaii
For nice weather, great prices, and fewer crowds on your Hawaiian cruise, we recommend booking during the off-season. May through June, and September through early December, are the best months to enjoy affordable, less crowded cruises.
Best Season for Fishing in Hawaii
Want to tell the ultimate fish tale? Then plan on putting some time aside to cast a line or two during your trip. You can expect to catch different fish depending on the season. Summer is ideal for marlin and ono. Spring and fall offer the best chance at landing mahi-mahi. Winter is the time to catch snapper and tuna.
Hawaii Weather by Month
The weather in Hawaii varies from perfect to utter bliss. There really is no “bad” time to visit, Hawaii weather is great year-round. May through September see the least precipitation, but the summer months can feel a bit warm for those unaccustomed to tropical weather. The best all-around weather is in April, May, September, and October.
