What is the best time to visit the Big Island?

Whale season on the Big Island runs from November through April, and it’s the only time of year you’ll see humpbacks offshore. Winter brings its own tradeoffs too: snow can close the Mauna Kea summit for days at a time, while the eruptions at Kīlauea keep going regardless of season.

One trick worth knowing before you book: Hilo gets over 100 inches of rain a year while Kona sees 20 to 30, so staying on the west side in winter is the simplest way to dodge most of the wet season. From there, the right month depends on whether you’re chasing beach days, lower prices, or fewer crowds.

Why Visit the Big Island?

The Big Island is larger than all the other Hawaiian islands combined, and it holds 8 of the world’s 13 climate zones on one landmass.

On a visit, you can taste fresh Kona coffee in the morning, stand amongst the snow atop Mauna Kea at nearly 14,000 feet in the afternoon, and then explore white, black, and green sand beaches at sea level at sunset. The island is home to five volcanoes, including Kīlauea, one of the world’s most active volcanoes, as well as many historical and cultural sites.

Green Sand Beach (Papakōlea) on the Big Island is one of only two green sand beaches in the United States.

What is the best time to visit the Big Island?

Temperatures barely swing here, but ocean conditions, rain, and daylight hours shift enough to change what’s possible on any given trip.

The answer to “what’s the best time to visit” is: it depends on what you’re doing and what you’re willing to pay.

What is the best time to visit the Big Island for the beaches?

Summer wins for beach days, with spring and fall close behind. Winter still delivers sun sometimes, just with worse odds, so for the most consistent beach weather, plan between May and October.

What is the best time to visit the Big Island to see whales?

Whale season runs during the winter months, from November through April. This is the only time frame you can see humpback whales in the islands; whale watching tours ramp up from mid-December and run until early April. January, February and March tend to be the peak months for whales.

What is the best time to visit the Big Island for snorkeling?

Snorkeling works on the Big Island in any season, but spring, summer, and fall carry better odds of calm water. Winter brings a higher chance of swell and storm swings that can shut down a session with little warning.

So, if you have your heart set on multiple days of snorkeling in multiple places, you should plan for the summer months, just to be safe. If you want to snorkel maybe once or twice and aren’t too particular about it, you can feel free to go any time of year.

What is the best time to visit the Big Island for the volcanoes?

Nothing in the seasons will affect the activity of the volcanoes on the Big Island. They erupt (or don’t erupt) in winter just the same as they do in summer, and there is no data to support that eruptions are more likely at certain times of the year.

The thing to keep in mind about volcanoes and the seasons is the weather at the summits. Kīlauea’s summit sits inside Hawaiʻi Volcanoes National Park at 4,000 feet above sea level, while the summit of Mauna Kea is about 13,800 feet. Only 4WD vehicles are allowed past the Visitor Information Station at 9,200 feet on Mauna Kea, year-round, and most rental cars aren’t permitted to make the drive, so check with your rental company before you plan on it. During winter, the summit road can also close outright due to snow and ice. (A cool winter day at Kīlauea, meanwhile, is often the easiest time to hike the lava fields, which turn brutally hot by midsummer.)

There will be, however, more variable weather patterns in winter, and a higher chance of rain and wind. For those wanting to visit the summit of Mauna Kea and do some stargazing, spring, summer, and fall are the best options.

• See our guide on how to see lava on the Big Island for planning details.

What is the best time to visit the Big Island for hiking?

Each season in Hawaiʻi brings about different opportunities for hiking.

Winter: Coolest temperatures, great for exploring coastal lava fields. Cold temperatures at higher elevations could make certain hikes undesirable, such as the summit area of Mauna Loa.

Spring: A great time to explore the rainforests, after winter rain has bulked up the waterfalls.

Summer: Best time to explore high elevations. Rainforests, summit areas, and forest hikes provide lots of shade during hot days. Hikes without shade, such as coastal lava fields, may be uncomfortably hot.

Fall: Cooler, dry weather makes hiking pleasant almost anywhere, though higher elevations call for a bit more gear as temperatures drop.

What is the best time to visit the Big Island “on the cheap?”

September is the real bargain month for Big Island accommodation, with August, October, November, and May also running below average. Summer carries high rates too, but the single priciest stretch is the holiday season, Thanksgiving through New Year’s.

January and February are the exception to the usual off-season logic: whale season and mainland snowbirds keep both months running above the annual average, so don’t expect a shoulder-season discount then.

Of course, keep in mind that the Big Island has limited accommodation options compared to, say, Oʻahu, so don’t expect prices to swing wildly, especially in the most popular areas, such as downtown Kailua-Kona.

How nightly rates move through the year

These two charts show the pattern behind the advice above. Vacation rental and hotel rates on the Big Island climb for the December holidays and the summer break, then drop in the spring and fall shoulder weeks. Both track three years of Hawaiʻi Tourism Authority reporting and update automatically, so they stay current no matter when you read this.

What is the best time to visit the Big Island if you want to skip the crowds?

September is the unambiguous quiet champion on the Big Island, with November and May also running well below average. February is not, though, and neither is January: by HTA’s average daily census, whale season and mainland snowbirds make December, January, and February the three fullest months on the island. Spring break scrambles March and April, some weeks quiet, some slammed, and summer runs above average too.

Visitors on the Big Island on an average day, by month, 2024 and 2025. September is the emptiest month by a wide margin, with May, August, and November also below the yearly average. December and January are the fullest.

What is the best time to visit the Big Island for the weather?

It depends on what weather you prefer.

Summer suits sun-seekers. Winter suits people who want the waterfalls running full and don’t mind clouds.

What is the best time to visit the Big Island for active travelers?

June days on the Big Island run about 2.5 hours longer than December days, real extra daylight for an active itinerary.

A Month-by-Month Breakdown of Big Island Weather

Here’s what to expect month by month on the Big Island, from rainfall to temperatures.

Spring: Late March through May

Mostly pleasant weather with some leftover showers from the winter rainy season. East and north facing shores could still receive some bigger swells, but overall, it will be trending toward calmer conditions. Waterfalls will be at their max after months of winter rain. Temperatures land in the mid-to-high 70s.

Summer: June through Early September

Hello beach days and hot sun. Temperatures will climb into the 80s and even low 90s at times on the western shores of the Big Island. Passing tropical showers are normal, but day-after-day of rain is unlikely, especially on the west side. The ocean is relatively predictable and calm, with the majority of beaches fit for swimming.

Fall: Late September through Early November

Fall’s “cooling off” reputation is generous for its first half: late August through early October is the hottest, most humid stretch of the year, and it overlaps the tail of hurricane season (June through November, peak August and September; direct hits are rare, but a passing storm can close shops and parks for a day or two).

Real cooling starts by mid-October, with temperatures easing to the high 70s or low 80s. The second half of fall brings the beginning of the rainy season, with a greater chance of inclement weather in November.

Winter: Late November through Early March

The winter, or “makahiki” season in the islands, is when there is the greatest chance of rain and stormy weather. Sunny days are still common, although the islands do get a major dose of precipitation during these months, especially on the eastern shores. Temperatures are in the low 70s with cooler nights. The ocean is more turbulent during the winter, which could complicate some activities, like swimming or snorkeling.

Cooler temperatures open the door for more comfortable hiking conditions, however, and the vibe around the islands is even more relaxed than normal due to the shifting weather.

How to Avoid Rain During the Winter Season on Big Island

Winter is wetter, but it’s also whale season, big-wave surf season, and the season when waterfalls run full and prices and crowds drop.

Storm systems do roll through in winter, but rain on the Big Island falls in specific places, not everywhere at once.

For example: The eastern (windward) sides of the Big Island (and all Hawaiian Islands) get the most rain. The western or leeward coast is drier. On Big Island, Hilo (east side) receives more than 100 inches of rain per year; meanwhile, parts of Kona (west side) receive just 20-30 inches per year.

If it’s raining on the east side, the west side is often sunny.

If dodging rain matters more to you than anything else, book your winter stay on the Kona side.

Where These Price and Crowd Numbers Come From

The price and crowd claims on this page aren’t guesses. Hotel and vacation rental rates come from our own trip cost calculator’s rate tracker, averaged across 2023 through 2025 by month. Crowd levels come from Hawaiʻi Tourism Authority data for 2024 and 2025: the chart and the busy-or-quiet calls in the text both use HTA’s average daily census, the count of visitors on the island on a given day. We revisit both periodically as new data comes in, most recently in July 2026.
