The Big Island of Hawaii, also known simply as Hawaii Island, is a destination that offers something magical every month of the year. Its diverse climates, wide range of outdoor activities, and rich cultural heritage make it a year-round paradise. However, the best time to visit can depend on what kind of experience you're looking for and what you value on vacation. Are you looking for perfect beach weather? Fewer crowds and cheaper accommodation? Cultural festivals? Wildlife viewing? Keep reading for all the details on all of Hawaii’s magical seasons and the best time of year to visit The Big Island.

East vs. West Coast Weather and Climate

No matter the season, it's important to consider the Big Island’s diverse geography. The western coast, where Kailua-Kona is located, is known for its dry, sunny climate and stunning beaches. It’s a favorite for beachgoers, snorkelers, and sunset seekers. 

On the other hand, the eastern side, where Hilo is, receives more rainfall and is home to lush rainforests, waterfalls, and botanical gardens. The island’s interior and higher elevations, like Volcanoes National Park and Waimea, are usually a bit cooler!

What Is The Best Time Of Year To Visit The Big Island?

Choosing the best time to visit ultimately depends on your priorities. If you're hoping to travel a bit more affordably and with less crowds (although Hawaii is certainly not considered an affordable destination to travel to), you’ll want to travel in late spring or early fall — the shoulder season. Specifically mid-April to early June or September through early December offer excellent weather, affordable rates, and a quieter experience.

For beach lovers and those focused on water sports, the calm, warm waters of summer are unbeatable. Whale watchers will find the best sightings from January to March!

Month-by-Month Highlights

January – March: Best for whale watching and waterfalls. Expect higher crowds and prices.

Hawaii doesn’t experience dramatic seasonal changes, but winter still brings some noticeable shifts. From December through February, temperatures remain mild, with daytime highs in the upper 70s. The east side of the island, particularly around Hilo, sees frequent rain showers. Meanwhile, the west side near Kona stays relatively dry and sunny, making it a comfortable base for winter travelers!

This season is also the busiest, especially around Christmas and New Year’s, so travelers should expect higher hotel prices and more crowds at popular attractions. However, winter is also prime time for humpback whale watching! These majestic creatures migrate to Hawaii’s warm waters between January and March, offering unforgettable opportunities for boat tours and coastal sightings.

April – May: Ideal shoulder season with lower costs & comfortable weather.

Spring on the Big Island, spanning March through May, offers a welcome break from the high-season bustle. The weather remains warm and pleasant, with less rainfall than in winter. March can still see occasional showers, but April and May are generally drier, making this an excellent time to explore both coasts.

Crowds thin out considerably during these months, creating a more relaxed travel experience. Hotel rates are more affordable, and you’ll find plenty of space at beaches and attractions. One cultural highlight of the season is the Merrie Monarch Festival in April, held in Hilo. This internationally renowned event showcases traditional hula, Hawaiian music, and local arts, drawing visitors from around the world.

June – August: Great for family trips and outdoor adventures, but prepare for crowds.

Summer on the Big Island brings reliably sunny weather and long days perfect for outdoor adventures. Average highs climb into the low 80s, ideal for swimming, snorkeling, hiking, and exploring the island’s many beaches and parks.

This season is especially popular with families due to school vacations, so while the weather is nearly perfect, expect larger crowds and higher prices. That said, the island’s size and diversity mean it rarely feels overrun. There’s plenty of room to spread out and find quiet moments, even in the summer months. Cultural festivals, farmers markets, and community events are plentiful during this time, and June features King Kamehameha Day, honoring the unifier of the Hawaiian Islands.

September – November: Best overall value — warm, quiet, and beautiful.

Many consider fall the best time to visit the Big Island. September through November offers warm, dry weather — especially in September and early October, alongside significantly fewer tourists. As kids return to school and the summer rush fades, prices on flights and accommodations drop, making this a budget-friendly and peaceful time to travel. This is when I visited Kona just last year and stayed at the Mango Sunset BnB and couldn’t recommend it more!

The fall season is also excellent for ocean activities. Water visibility is at its peak, making it ideal for diving and snorkeling. In October, Kona hosts the Ironman World Championship, drawing elite athletes and sports enthusiasts, while September features the Hawaii Island Festival, celebrating local culture with food, music, and dance.

While late fall brings the beginning of Hawaii’s rainy season, showers tend to be brief and mostly affect the eastern side of the island. Showers in Kona will just be passing!

As you can see — there are no bad times to visit the Big Island! It’s all based on personal preference.
