At just over 4,000 square feet—and still growing—the Big Island of Hawaii is the largest island in the United States. The best time to visit is typically from April to June or from September to October. Here is where the wildly rugged landscapes of the dense jungle and majestic volcanic terrain meets miles of blue coastline with diverse geography. Almost all of the world’s climate zones are represented on Hawaii Island as well, so knowing the best time to visit this special place can make or break a vacation.

A majority of Hawaii Island’s visitors come during the summer months when the kids are out of school, as well as during the winter holiday season. The “autumn” months bring the same great Hawaii weather with slightly lower temperatures and fewer crowds. Big events like the Ironman Triathlon in October and the Merrie Monarch Festival in April generate a large number of visitors, though generally just for small pockets of time.

The Weather on Hawaii Island

While the weather on Hawaii Island doesn’t fluctuate much throughout the year, June through August tends to see the year’s hottest temperatures. However, since this island contains some of the most diverse terrains and microclimates in Hawaii, the weather can change at a moment’s notice. The tropical temperatures range from 75 degrees Fahrenheit to 85 degrees Fahrenheit (24 degrees Celsius to 29 degrees Celsius) year-round for the majority of the island, with lower temperatures the further from the coast you travel. While most of the island will not see any snow, it often snows on the mountaintops of Mauna Kea and Mauna Loa during winter.

Hawaii Island’s Crowds

Hawaii Island is just that—big. Depending on which part of the island you’re on, you may not experience any annoyances due to large crowds. The Kailua-Kona side of the island usually sees the largest number of tourists, followed closely by Hilo on the east side and Waimea on the north side. Summertime is the busiest due to the number of families coming over for school breaks. Winter is also a very busy time for those wanting to swap their chilly hometowns for some of Hawaii’s famous warm weather or large surf.

Prices on Hawaii Island

Compared to the rest of the main Hawaiian Islands, Hawaii Island is generally much cheaper when it comes to accommodations. Unless you rent a car or book a tour, you will probably be spending the majority of your time at your resort, so choosing the right place to stay is paramount. On the off-seasons from September to November and again from March to May, accommodation and flight prices will be lower to compensate for the smaller crowds. 

Whale Season on Hawaii Island

Humpback whales visit the waters of Hawaii from December to April or May every year, so coming during these winter months will give you a great opportunity to go whale watching on Hawaii Island.

January, February, March

Come during this time if you’d like to catch a glimpse of Hawaii Island’s migrating humpback whales. For big wave surfers, the best waves can be found during these winter months as well. Keep in mind that during the winter months on the mainland U.S. and in other countries, more people tend to flock to Hawaii Island in order to escape the cold.
