Why Now is the Best Time to Go to Big Island, Hawaii

When is the best time to jet off to the largest of Hawaii’s islands, known for its diverse climates, active volcanoes, and tropical beaches? 

During my travels, I explored every corner of this island for over two weeks at the beginning of December. Although it is considered to be the rainy season, I found it a great time to visit. And there wasn’t even that much rain.

The weather on the Big Island is filled with microclimates as varied as its landscapes, ranging from sunny beaches to windy mountaintops. So, here’s a quick guide to the visitor seasons:

• Peak Season: March, June to August, and December to January
• Off-peak Season (and Best Months): April to June, September, October.
• Rainy season: November to March
• Dry season: April to October

Now, let’s take a closer look at the seasons, cool events to see, and what the weather is typically like. Whether you’re planning a short getaway to the Big Island or a longer adventure, sunbathing on Green Sand Beach, or watching the lava flow at Hawaii Volcanoes National Park, this is the best time to visit Big Island Hawaii.

Best Time to Visit Big Island

Best Time of Year to Visit

Compared to the mainland, Hawaii has incredible weather all year round, so you really can’t go wrong any time of the year. But to maximize the sunny days and the fewer people, the best time to go to the Big Island is from April to June and September to November. 

These months fall in the island’s dry season, with mostly sunny weather and fewer crowds. Plus, with the island less packed, you can snag some better deals on accommodations and activities.

Best Time for Good Weather

Come to the island during the dry season between April and October if you’re after that perfect mix of sunny skies and comfortable temperatures. That being said, the temperature throughout the year doesn’t vary too much, and even having gone in the rainy season, I still experienced plenty of sunny days.

However, if you want to avoid the heat and humidity, plan your visit in the winter months between November and March when temperatures are slightly cooler.

Best Time to Avoid Crowds

For fewer crowds, avoid the peak season months when school is out of session and Hawaii becomes a tourist hotbed. This would include spring break, the summer months, and winter holidays. 

The Big Island has relatively less tourism than places like Maui and Oahu. However, these months still see an influx of tourists overall and higher prices for accommodations and activities.

Cheapest Time to Visit

For cheaper accommodation and activities, come during the off-peak months or, at the very least, avoid the school holidays and the summer months. Flights are significantly more expensive, plus hotels can be more than 30% more expensive.

Worst Time to Visit Big Island

If there’s a time you might want to skip the Big Island, it’s during the peak of summer, specifically July and August. These months aren’t just sweltering, but the island gets crowded with families on summer break. Plus, prices for accommodations and flights can skyrocket, making it a less ideal time for travelers looking to make the most of their budget.

Seasons of Big Island

Spring (March to May)

From March through May, the island gradually shakes off the mild chill of winter, with temperatures comfortably sitting between the mid-60s to low 80s Fahrenheit. In the uplands, the cherry blossoms in Waimea draw locals and tourists alike. Down at the beaches, the ocean is tranquil, ideal for snorkeling and swimming, with sea life becoming more active and visible. 

Rainfall is present, but often in short, refreshing bursts. These bursts come with the bonus of colorful rainbows, which are amazing to witness in waterfalls like Rainbow Falls. 

Key Events: 

• Kona Brewers Festival (March): This festival at the King Kamehameha’s Kona Beach Hotel Luau Grounds in Kailua-Kona features microbreweries from all over delivering their best brews.
• Merrie Monarch Festival (March-April): This week-long event follows Easter Sunday and is a huge deal in Hilo. It’s a dance competition celebrating Hawaiian culture, art, and history.
• Big Island Chocolate Festival (April): Held at the Waikoloa Beach Marriott Resort, this event is all about chocolate with tastings and cooking demos.

Summer (June to August)

From June through August, the island’s beaches and attractions are bustling with families and adventurers looking to soak up the Hawaiian sun. Temperature-wise, balmy days average between 85°F and 90°F, though the humidity may be overwhelming on some days. 

Go on snorkeling and scuba trips during the summer, as the dolphins and manta rays are very active. On land, the fields and forests are alive with wildlife, and the longer days mean more time for hiking through the volcanic landscapes or lounging on black, green, or white sandy beaches—yes, there are all three colors!

Summer is also festival season. The Kona Marathon, the Annual Cultural Festival, and the Hawaii Volcanoes National Park Cultural Festival are opportunities to dance, eat, and laugh with the locals.

Summer does bring crowds. Schools are out, families are vacationing, and everyone wants their slice of paradise, meaning popular spots can get pretty packed. And with the demand, prices for accommodations and activities shoot up, making budgeting a bit more of a challenge.

Key Events: 

• King Kamehameha Day Celebration Floral Parade (June): Streets lined with colorful floats, marching bands, and dancers, all paying homage to King Kamehameha I.
• Hawaiʻi Volcanoes National Park Cultural Festival (July): Get ready for a day packed with traditional crafts, music, and hula that celebrate the rich culture of Hawai’i.
• Big Island Jazz & Blues Festival (June): This event brings together some of the biggest names in jazz and blues for a series of concerts.
• Parker Ranch Independence Day Rodeo and Horse Races (July 4th): This event features traditional rodeo competitions, horse races, and many family-friendly activities. 
• Mango Festival (July): The Mango Festival celebrates all things mango with cooking demonstrations, tastings, and workshops. Learn about the different varieties of mangoes, their health benefits, and how to incorporate them into your cooking.

Fall ( September to November) 

The pace of life gently slows down in Autumn with vacationers returning to school and their jobs. The island feels more ‘local.’ With the peak tourist season behind them, you’ll find local events, from small-town rodeos to community markets.

Temperature-wise, the mercury returns to the comfortable 70s to low 80s°F, with the humidity dialing back to more crisp, pleasant evenings. The ocean remains invitingly warm, with excellent conditions for swimming, snorkeling, and even catching the early season waves that start to pick up on the island’s surf spots.

The more competitive prices are here. Since fall is considered a ‘shoulder season,’ you’re likely to snag some excellent deals on accommodations and activities.

Key Events: 

• Annual Hawaiian Slack Key Guitar Festival – Kona Style (October): This month-long festival celebrates the music of Hawaii’s unique guitar style.
• Hawaii Food and Wine Festival (October): This epicurean adventure spans three weekends to munch through the best local cuisine, wine, and cooking talent.
• Ironman World Championship (October): Witness the pinnacle of human endurance at the Ironman World Championship in Kona.
• Kona Coffee Cultural Festival (November): Celebrate Kona’s world-famous coffee with nearly 50 events over 10 days, including tastings, farm tours, and barista competitions. 

Winter (December to February) 

Winter on the Big Island brings cooler evenings and the sight of humpback whales breaching off the coast. With temperatures still ranging from mid-60s to low 80s°F, the island remains a warm escape for those fleeing colder climates. 

Lush rainforests receive nourishing rains, while the summit of Mauna Kea may even boast a delicate dusting of snow. Beach days are still a joy, with warmer ocean currents. Surfers also find their paradise, with the winter swells providing some of the year’s best waves. 

Despite being part of the high season due to holiday travelers, the rest of the season sees moderate tourism, and you’re likely to find some off-peak prices on accommodations and activities. 

Key Events: 

• Waimea Twilight Christmas Parade (December): Floats, bands, and dancers light up the night, spreading cheer throughout Waimea.
• Christmas With The Chefs Fundraiser (December): Local chefs share their talents with delicious dishes, all in support of local culinary students.
• Hawaiʻi International Music Festival (January): Experience the world through music at this festival that presents artists from around the island.
• Waimea Cherry Blossom Heritage Festival (February): Waimea turns pink with cherry blossoms, and there’s live music, a Malasada 5K run, and a Spring Festa. It’s a beautiful blend of Japanese and Hawaiian culture.
