Written By Jenny White | The Kai Life • Posted on November 16, 2025

Thinking of Visiting Hawaii in January?

It’s a wonderful time on the islands! Hawaii in January is a dreamy escape post-holidays, and one of my favorite times to visit.

I’ve visited the islands more times than I can count (including in January), and I created this guide to help you skip the guesswork and know exactly what to expect about visiting Hawaii during at the start of the year.

While January does bring slightly cooler temps and more of a chance of rain, Hawaii is pretty much always warm and tropical! I’ve always lucked out with gorgeous weather in January. I love the mellow vibe right during the last part of the month. There’s something about getting out of town when the weather is cold and the holiday fun is over!

Whether you’re wondering if it’s the best time to visit, curious about costs and crowds, or planning a winter wellness trip, this post breaks it all down for you.

Short on time and wanting the highlights about January in Hawaii?
January Hawaii Weather : Expect daytime temps in the low-to-mid 80s, cooler evenings, and occasional quick rain showers (especially on north and east shores).
January Crowds : The first two weeks are still peak season, but things quiet down beautifully after mid-month – it’s one of the calmer times to visit.
The Best Activity in January : Whale watching, hands down – it’s peak season, and you can often spot them right from the shore!

Hawaii in January: What to Know Before You Visit

January in Hawaii really brings a mix of energy. With the busy holiday season finishing up during the first two weeks, you’ll find way less crowds the last half of the month. You can expect slightly milder temperatures compared to summer or fall, and a higher chance of rain.

January is also peak season for one of the island’s most beloved winter highlights: humpback whales. If you’re thinking about escaping the cold or chasing post-holiday sunshine, you’ll love January as a time to visit the islands!

Why You’ll Love Visiting Hawaii in January

If you’re craving warmth, ocean views, and a reset after the holidays, Hawaii delivers. This is the time of year when the islands feel both peaceful and alive — with a calmer energy once the New Year rush settles down.

Whether you’re watching whales breach off the coast or stretching out on a quiet beach, January offers a mellow start to the year in a place that already feels like a breath of fresh air.

Why January Is One of the Best Times to Visit

• Peak whale watching season – see humpbacks, literally from the shore.
• Fewer crowds after the first week or so of January.
• Better travel deals on flights and stays after the holidays.
• Pleasant weather that’s absolutely warm enough for beach days, on most days.
• Great time for wellness trips (kicking it off with that new-year reset!).
• Lush landscapes thanks to winter rain on the windward sides.

Things To Consider About A January Trip To The Islands

While January can be a beautiful time to visit, there are a few things to consider before booking your tickets.

It’s cooler, sometimes wetter, and the beginning of the month can feel crowded with post-holiday tourists. That said, if you’re flexible and know what to expect, you’ll likely fall in love with the mellowness of this season.

Why January Might Not Be the Best Time to Visit Hawaii

• Rain is more frequent this time of year following December (Hawaii’s rainiest month!), especially on the north and east shores.
• Ocean conditions can be rough, especially on the North Shores – which can limit swimming/snorkeling on some beaches.
• You may find that you need layers at night, and some days can be cooler than the rest of the year.
• Early January is busy, with families extending holiday trips (avoid the first two weeks if you’re trying to avoid peak season!).
• Some tours book up fast, especially whale watching.
• Less daylight than in summer months — expect early sunsets.

The Weather : What’s January Like In Hawaii?

January weather in Hawaii is mellow, a little moody at times, and still completely vacation-worthy.

You’ll find warm temps most days – think low-to-mid-80s during the day – but with a slightly cooler breeze compared to summer or fall.

Nights can dip into the low 70s or upper 60s, especially on the north and east sides of the islands, so you might want to plan for light layers in the evenings.

It’s also one of the rainier months, particularly on windward sides and at higher elevations. That said, showers are often brief and followed by sunshine.

If you’ve been to Hawaii before, you already know: the weather can shift quickly from one microclimate to the next – on any island, during any season. On rainier days, we just head to the leeward (south and west) sides of the islands – they tend to stay drier year-round.

January Weather Stats Across the Hawaiian Islands

Weather can vary quite a bit depending on which island (and which side of the island!) you’re on. Here’s a quick look at what you can generally expect across the islands in January – from average temps to rainfall patterns.

Weather	Oahu	Maui	Kauai	The Island of Hawaii
Average High Temperature	78ºF/º26C	71ºF/22ºC	72ºF/29ºC	81ºF/27ºC
Average Low Temperature	63ºF/17ºC	55ºF/13ºC	54ºF/12ºC	66ºF/19ºC
Average Rainfall	3.5in/89mm	3.5in/89mm	5.2in/132mm	3in/75mm
Average Ocean Temperature	76ºF/24.5ºC	76ºF/25ºC	74ºF/23ºC	78ºF/26ºC

Is January Too Cold to Visit Hawaii?

Short answer: nope – not even close. Trust me, you’ll still be warm.

I’ve visited Hawaii during every month of the year – and let me tell you, it’s always warm and tropical compared to just about anywhere on the mainland in winter.

January is a little cooler than the summer and fall months, but it’s still beach weather almost every day.

Expect daytime highs in the low to mid 80s, and evenings that might dip into the low 70s or upper 60s depending on where you are. If you’re used to true winter temps, you’ll be peeling off layers the second you land.

Is Hawaii Rainy in January?

January is still part of Hawaii’s rainy season, and it often tapers off from December, which is typically the rainiest month of the year. So yes, you might see more showers this time of year – especially if you’re on the north or east sides of the islands.

But rain in Hawaii isn’t like mainland rain. It rarely lasts all day, often shows up as quick bursts, and almost always brings a rainbow (or two). You might drive through a downpour and be in full sunshine five minutes later. And when the skies do open up, everything turns lush, green, and wildly beautiful.

Which side of the island you’re on makes a big difference – the windward sides (north and east) tend to get the most rain, while the leeward sides (south and west) often stay dry and sunny. That’s where we usually head when clouds roll in.

January Ocean and Surf Conditions

January is full-on winter swell season in Hawaii – especially on the northern shores, where big, powerful waves roll in consistently. If you’re a surfer (or just love to watch), it’s an incredible time to witness the islands’ wave energy in full force.

But even for non-surfers, ocean safety is key this time of year. Conditions can shift quickly, and some beaches that are calm in summer can be dangerously rough in winter. Pay attention to this even while walking on the beach. Always check posted warnings, talk to lifeguards, and trust the signs – the ocean is no joke in Hawaii ever, but especially in the winter.

If you’re hoping to swim or snorkel, head to south-facing beaches which tend to stay much calmer this time of year. And as always, conditions vary by island, by beach, and even hour to hour – so stay flexible, and know that the island will always show you where it’s safe to go.

Can You Swim in Hawaii in January?

Yes – you can absolutely swim in Hawaii in January! The ocean stays warm year-round, and many beaches, especially on the south and west sides, are calm enough for swimming even in winter.

The key is knowing where to go.

Some beaches on the north shore can be too rough (or even closed) due to big surf, but spots like Waikiki, Poipu, and Ka’anapali often stay mellow and swimmable. As always, check conditions before heading out, and never swim at a beach that doesn’t feel safe – especially during winter swell season.

How Warm Is the Water in Hawaii During January?

Ocean temps in January usually hover around 76–78°F, which feels warm and refreshing – especially if you’re coming from a true winter climate.

You might feel a chill when you first get in, but it passes quickly (and honestly, it feels amazing after laying in the sun). No wetsuit needed – just dive in and enjoy.

Are the waves big in Hawaii During January?

Yes – January is prime time for winter swells, which means big waves in Hawaii, especially on the north and northwest shores.

This is when world-famous surf spots like Waimea Bay, Pipeline, and Jaws come alive with massive, consistent swells that are incredible to witness (even if you’re just watching from shore).

But bigger waves also mean stronger currents and potentially dangerous conditions. If you’re planning to spend time on a beach, whether or not you’re planning to get in the water – it’s always smart to check a local tide chart before heading out. It’ll help you time your beach days and know what to expect, whether you’re surfing, swimming, or just soaking it all in.

Hawaii in January: What It’ll Cost You

There’s no denying that Hawaii is an expensive destination to visit. But there are absolutely ways that you can make it more afforadable.

January can be a bit of a mixed bag when it comes to pricing – the first two weeks of the month are still considered peak season, thanks to the tail end of holiday travel. Expect higher rates on flights, hotels, and rental cars if you’re heading to the islands during that New Year’s rush.

But after mid-month? Things start to shift. Post-holidays usually bring better deals, lighter crowds, and more flexibility – especially if you’re traveling mid-week or avoiding holiday weekends. You won’t find the absolute lowest prices of the year (those tend to pop up in late spring or fall), but it’s still a solid time for snagging value in paradise.

How To Save On A January Trip To Hawaii

If you’re planning a January trip and hoping to save, try to book your flights and stays for the second half of the month – after crowds thin out and prices drop. Avoid New Year’s week if you can, and watch for shoulder-week airfare deals that sometimes pop up last-minute.

Another tip? Consider less tourist-heavy islands or towns. Maui and Oahu tend to stay pricier, while Big Island and Kauai often have better deals – especially if you’re open to vacation rentals instead of big resorts.

Are the Islands Busy in January?

January starts off busy. The first two weeks are still considered peak season, with lots of families wrapping up holiday vacations and flocking in for sunshine. Expect fuller flights, more crowded beaches, and higher prices if you’re traveling around New Year’s.

But things shift pretty quickly after that. Mid-to-late January when kids are back in school brings a noticeable drop in crowds. It’s one of those sweet spots where you can still enjoy great weather, but with a little more breathing room.

Is One Island Less Crowded Than the Others in January?

Oahu and Maui tend to be the busiest islands year-round – and that’s still true in January. Oahu especially stays popular thanks to its mix of city, surf, and famous sights, while Maui draws travelers for its resort scene and winter whale season.

If you’re looking for a quieter January escape, consider Kauai or the Big Island. They both offer a slower pace, more room to explore, and smaller crowd sizes.

Since January crowds thin out after the holidays, you’ll find peaceful pockets almost anywhere – especially if you’re up early or head off the beaten path.

Best Events & Things to Do in Hawaii in January

While January is lighter when it comes to festivals and gatherings, it’s a beautiful month for outdoor events, learning about the Hawaiian culture at your own pace, and unforgettable wildlife experiences.

Whether you’re catching a live show, wandering a weekend market, or watching whales breach offshore – there’s still plenty happening across the islands.

1. Go Whale Watching

January is peak humpback whale season in Hawaii, as thousands of these giants migrate from Alaska to give birth and mate in warm island waters.

It’s one of the most magical winter sights you can experience – and you don’t even need a boat to see them.

? I love this catamaran whale watching tour that takes off from West Maui. It has all 5 star reviews with a ton of other Hawaii visitors that agree.

Whale activity is strongest off the coast of Maui, especially around Lahaina and Maʻalaea Bay. But you can spot them from land on every island. Here’s where to look:

• Oahu: Makapuʻu Lighthouse Trail – a favorite for sweeping coastal views and spouts offshore. I’ve also had great luck spotting them off of the southern Ko Olina resorts.
• Maui: Papawai Scenic Lookout – just outside Lahaina, one of the best roadside viewing spots. In Maui, you can also ride on an eco-raft and see them up close!
• Kauai: Kīlauea Lighthouse – panoramic ocean views and frequent whale sightings
• The Island of Hawaii: Puʻukoholā Heiau – north of Kona, a peaceful and historic bluff with a great vantage point

Whale watching cruises are also super popular this time of year if you want a closer look – especially out of Lahaina, Kīhei, or Wailea.

Tip : To spot them, look for spouts, splashes, or full breaches (you might even catch a tail slap!).

Oahu In January : Things To Do & Events

Oahu brings a great mix of events in January – from iconic surf culture and community races to one of Honolulu’s most beloved New Year celebrations. If you’re looking for something beyond the beach, these are a few worth checking out:

2. Kick Off The New Year With A Traditional Event

Hosted by the Japanese Cultural Center of Hawaii, the New Years ‘Ohana Festival celebrates the New Year with food, entertainment, crafts, and taiko performances. It’s a beautiful blend of local and Japanese traditions.

It typically takes place the second week in January.

3. Go For A Hike With Ms. Hawaii

One of my dearest friends is Ms. Hawaii! As an avid fitness enthusiast and guide, she takes visitors up Oahu’s famous Koko Crater Railway Trail.

You’ll climb up 1,048 historic steps to the summit for views of Hanauma Bay, Diamond Head, and the coast.

Nicole is the kindest person and is such a blast to hang out with. She’ll keep you motivated during this challenging hike. She loves Hawaii inside and out, and will give you great tips for the rest of your trip. You’re in the best hands with her!

4. Watch World Famous Surfers Compete

If swells at Waimea Bay are big enough, the legendary Eddie Aikau Big Wave Invitational surf competition is a must-see. “The Eddie” only runs under perfect conditions, so keep an eye on surf forecasts if you’re on Oahu in January.

5. Visit A Local Favorite Beach

Wanting to experience Waikiki beaches without the intense crowds? Head towards the eastern end, where Kaimana Beach invites you to stay all day. It’s walking distance of Waikiki, but much quieter.

Here, you’ll find swimmable waters (perfect for paddle boarding), have access to bathrooms and a lifeguard. I’ve spotted seals and turtles on this beach.

You’ll love having access to Hau Tree Restaurant at the bottom of Kaimana Beach Hotel.

Tip : Kaimana Beach Hotel is one of my favorite beachfront hotels in Hawaii! If you stay here, be sure to splurge for an oceanfront room or suite.

Maui In January : Things To Do & Events

January is a mellow month on Maui. It’s perfect for relaxation, and keeping your eyes on the ocean horizon for whales. Whether you’re running along the coast or leaning into a post-holiday reset, this island makes it easy to start the year off right.

6. Run In (Or Cheer On!) A Marathon

Held each January, the Maui Oceanfront Marathon takes runners from Wailea to Lahaina, offering stunning ocean views and a mix of athletic challenge + island vibes. Running with a Maui backdrop is always a better way to run!

7. Snorkel In Clear Protected Waters

Spend some time on Maui’s beloved Kaanapali Beach, and plan to snorkel at Black Rock. Black Rock is a volcanic rock that is known for its nightly cliff diving ceremony. It’s an excellent spot for snorkeling due to its clear visibility and protected waters.

Kauai In January : Things To Do & Events

Kauai is always a peaceful island to visit any time of the year, but it’s especially quiet in January. It’s a great pick if you’re looking for the combo of nature + culture without the big crowds.

8. Tour The Grand Canyon Of The Specific

One of Kauai’s natural wonders, Waimea Canyon is an incredible place to explore and take in. Level up your time spent in the canyon with a private all day tour, led by a local. You’ll leave the driving to someone else so that you can take it all in, and have an insider guiding you on all the best spots.

? Check out my favorite private Waimea Canyon Tour here!

9. Visit Farmer’s & Artisan Markets

Honestly, I love visiting the Hawaiian markets during any visit to the islands. You can find them pretty much any day of the week throughout each island. It’s a wonderful opportunity to purchase local food and art, to meet wonderful people – and to slow the pace a bit.

Tip : I typically jot down all the markets during the dates of my visit so that I have them at hand wherever our adventures lead us. Go Hawaii has a fantastic list of all the farmers markets.

10. See The Na Pali Coast From The Skies

I continually recommend this Private Doors-Off Helicopter Tour, and there’s a reason that it’s 5-Star Rated. Seeing Kauai from the skies is truly a once-in-a-lifetime experience that you’ll never forget.

January is a really great time for the tour – not only will you gets views of Kauai favorites like the Na Pali Coast and Waimea Canyon – but you can even spot humpbacks from the skies!

The Island Of Hawaii In January : Things To Do & Events

The pace of the Island of Hawaii is always wonderful contrast to busier resorts and buzz. It’s perfect if you’re seeking space, nature, and that luxe‑coastal lifestyle without the crowds.

11. Help In A Whale Count

Each year the The Sanctuary Ocean Count invites visitors and locals alike to scan shorelines for humpback whales and note behaviors in the ocean. Held on the last Saturday of January (and again in February and March), it’s a meaningful way to engage with the whale season while being part of conservation.

12. Stargaze Under The Winter Skies

January is one of the best times to stargaze under the clear night skies of the Island of Hawaii.

Head to the summit of Mauna Kea, The Island of Hawaii’s tallest peak just before sunset. After watching the sun dip, you’ll be treated to a telescope, hot chocolate, desert and a hooded parka to watch the skies.

? This is the small group stargazing experience that we love.

Or, you can take off for a day experiencing Hawaii’s favorites like local coffee and sweet bread, visiting a black sand beach, checking out Volcanoes National Park – and ending the day with a guided stargaze.

January in Hawaii: What to Pack

In January, the weather is still tropical, but you’ll want to be ready for quick rain showers and slightly cooler evenings. Here’s what I always recommend tossing in your suitcase:

• Light layers – Think breezy long sleeves or a thin sweater for evenings or early mornings.
• Compact rain poncho or light rain jacket – Showers are usually brief, but I always carry one with me in Hawaii, to be ready.
• Binoculars – Perfect for whale watching from the shoreline during peak season.
• Swimsuits – You’ll still be living in them most days.
• Cover-ups + casual dresses – Easy to throw on after the beach.
• Comfy sandals and water shoes – For beach hopping and exploring lava rocks or tidepools.
• Reef-safe sunscreen and SPF lip balm – The sun is still strong, even in winter
• Dry bag or waterproof pouch – Great for boat tours, beach days, or rain sprinkles.
• Sun hat + sunglasses – A must year-round.
• Reusable water bottle – Stay hydrated, especially if you’re out adventuring.
• Small daypack or beach tote – For daily essentials on the go.

FAQ’s

As someone who visits Hawaii during every season, these are the questions that I’m often asked to help others have their best trip :

What’s the best island to visit in Hawaii in January?

If whale watching is on your list, Maui is hard to beat in January. It offers the best up-close experiences (both from shore and on the water).

Every island has its charm this time of year, though. Kauai and the Island of Hawaii tend to be less crowded, while Oahu gives you a little of everything.

Is Hawaii swimmable in January?

Yes! The ocean is warm year-round in Hawaii. Be mindful of winter ocean conditions in January, though – especially on north shores, where waves can get rough. For calmer water, stick to lifeguard-monitored beaches on the south and west sides, and always check local surf advisories.

What are the best and worst months to visit Hawaii?

There’s no “bad” time to visit Hawaii. Some months bring better deals, fewer crowds, or more stable weather though.

Late spring (April–May) and fall (September–October) tend to offer the best balance of value, weather, and lighter tourism traffic.

December is the rainiest and most expensive month, especially around the holidays. January is a sweet spot after that rush, with the bonus of whale season and cooler beach days.

Final Thoughts : Hawaii In January

January might not be the absolute driest or hottest time to visit Hawaii – but it’s still an incredible month to be on the islands. With whale season in full swing, fewer crowds after the holidays, and cooler beach days that still feel like summer, it’s a special way to kick off the new year.

I’ve experienced both sunshine and showers this time of year, but I’ve always left feeling refreshed, inspired, and ready to come back again. I love visiting in January for a rejuevenating, slow-paced way to kick off my year.

Wherever your trip takes you, I hope it’s beautiful, relaxing, and full of unforgettable moments. Safe travels and soak it up – a trip to Hawaii really is the perfect way to kick off the new year.
