So you’re thinking about escaping to Kauai in January? Smart move.
I’m writing this wearing three layers because it’s freezing in Seattle, and I’m daydreaming about the last time I visited Kauai in January with my kids.
Let me tell you something: while everyone back home is scraping ice off their windshields, you could be watching humpback whales breach off the Na Pali Coast.
As someone who’s visited Hawaii over 40 times (yes, I’m a professional tourist and certified Hawaii Destination Specialist), I can confidently say January is one of the best months to visit Kauai.
Here’s why: smaller crowds than summer, perfect hiking weather, and whale season is in full swing.
Plus, you’ll dodge the holiday rush but still get that warm tropical escape your soul needs.
What’s Kauai Weather Like in January?
Let’s talk about what to actually expect weather-wise, because I get this question constantly.
January in Kauai is what I call “perfect sweater weather.” Daytime temps hover around 78-81°F, while evenings can dip to about 65°F.
That means you’ll want to pack a light cardigan or hoodie for evening dinners. My kids always joke that I’m overdressed when I bring a sweater, but trust me on this one.
The trade winds pick up a bit in January, which is fantastic for keeping you cool during hikes but can make beach days feel a touch breezy.
And yes, it’s the wet season, so you’ll want to check the forecast daily and have a backup plan.
But here’s the secret: the rain usually comes in short bursts, and you can often just drive to a different part of the island to find sunshine.
I’ve learned to embrace the occasional rain shower. Some of my favorite Kauai memories involve getting caught in warm tropical rain while hiking to a waterfall. It’s all part of the adventure.
The Absolute Best Things to Do in Kauai in January
1. Go Whale Watching (This is Peak Season!)
January is THE time to see humpback whales in Hawaii.
These massive creatures migrate from Alaska to Hawaii’s warm waters every winter, and let me tell you, watching a 40-ton whale breach right in front of you is absolutely unforgettable.
My family’s favorite spot for whale watching is taking a boat tour along the Na Pali Coast. You get the stunning cliffs AND whale sightings all in one trip.
We’ve also spotted whales from shore at Kilauea Lighthouse and from the Kalalau Trail overlooks.
You can book excellent whale watching tours through Viator or Get Your Guide, where they often have last-minute availability and good cancellation policies.
Pro tip from a Hawaii travel expert: morning tours tend to have calmer seas, which is better if anyone in your group gets seasick.
Also, humpback whale season runs from November through April, but January and February are when you’ll see the most whales.
2. Hike the Sleeping Giant Trail
This trail holds a special place in my heart. The legend behind it is that a giant named Nounou helped villagers build a massive earth oven for a feast, then ate so much he fell asleep and never woke up.
When you see the mountain from Kapaa, you can actually see his profile.
The hike itself is about 2 miles roundtrip (if you take the East Trail) with stunning 360-degree views at the top.
You’ll climb through ironwood forests and get glimpses of the ocean as you ascend.
Near the summit, there’s a picnic shelter where you can catch your breath before the final scramble to the very top.
Fair warning: that last bit requires some light rock climbing. The first time I did it with my kids, I was definitely nervous, but we all made it and felt so accomplished.
Start early to beat both the heat and the crowds. And please, wear proper hiking shoes. The trail gets muddy and slippery, especially if it’s rained recently.
3. Experience a Traditional Hawaiian Luau
Look, I know luaus can feel touristy, but they’re also an incredible way to learn about Hawaiian culture and traditions.
As someone who’s been dancing hula for over 20 years, I can tell you that the good luaus are doing important cultural work by keeping these traditions alive.
My family’s favorite is the Smith Family Luau at Wailua. The imu ceremony (where they unearth the kalua pig from the underground oven) is fascinating to watch.
The kids love the fire knife dancing, and the buffet always includes dishes you won’t find at regular restaurants.
Another excellent option is Luau Kalamaku at Kilohana Plantation. It’s performed in-the-round, so everyone gets a great view.
Book your luau tickets in advance through Viator or directly with the venues. January is less crowded than summer, but the popular nights still sell out.
4. Explore Kilauea Point Lighthouse and Wildlife Refuge
This is hands-down one of my favorite spots on the entire island. Perched 200 feet above the ocean on Kauai’s northernmost point, the lighthouse was built in 1913 and is absolutely gorgeous.
But honestly? The real stars here are the seabirds. You’ll see red-footed boobies nesting right along the walkway, Laysan albatross soaring overhead, and if you’re really lucky, you might spot Hawaiian monk seals or sea turtles in the water below.
Here’s what you need to know: the refuge now requires advance reservations through Recreation.gov.
It’s only open Wednesday through Saturday, 10 AM to 4 PM, and you’ll need to book up to 60 days ahead. Entry is $10 for adults (plus a $1 reservation fee), but kids under 16 are free.
The America the Beautiful Pass is accepted here, which is a great deal if you’re planning to visit multiple national parks or refuges during your trip.
5. Relax at Lydgate Beach Park
When you have kids, finding a beach with calm water is gold. Lydgate Beach Park has these amazing rock-wall pools that protect swimmers from the waves and current. It’s like nature’s swimming pool.
The snorkeling here is fantastic, even for beginners. My kids saw their first sea turtle at Lydgate, and they still talk about it. The fish are used to people, so they swim right up to you.
There are lifeguards on duty, tons of parking, restrooms, and a massive playground. Honestly, it’s the perfect setup for families. Pack a picnic lunch and plan to spend half the day here.
Pro tip: the pools are calmest in the morning before the afternoon winds pick up. And yes, it can get a bit crowded on weekends, so weekday mornings are ideal.
6. Discover Old Koloa Town
This historic plantation town dates back to 1835 and has this charming, nostalgic vibe. My family always stops here for lunch when we’re exploring the South Shore.
The Koloa Fish Market serves these incredible plate lunches. Get the spicy ahi poke. Seriously, do it. There are also two food truck lots with award-winning trucks serving everything from fresh fish tacos to Korean bbq.
Browse the cute shops, check out the Old Sugar Mill Memorial, and soak in the small-town Hawaii atmosphere. It’s a nice break from the resort areas and gives you a real sense of Kauai’s history.
7. Take a Scenic Drive or Helicopter Tour
The views in Kauai are legitimately insane. I’m talking about Jurassic Park-level scenery (because yes, they filmed there).
If helicopters are in your budget, do it. You’ll see parts of the island that are completely inaccessible any other way, including the center of Waialeale Crater.
Book through Viator or Get Your Guide for the best rates and flexibility.
Not ready to splurge on a helicopter? The drive to Waimea Canyon (the “Grand Canyon of the Pacific”) is absolutely stunning and completely free. Just fill up your rental car and go.
Speaking of rental cars, I always book through Discount Hawaii Car Rental because they compare all the major companies and usually have the best rates.
8. Visit Tunnels Beach for Snorkeling
When the North Shore is calm (which it often is in winter mornings), Tunnels Beach offers some of the best snorkeling on Kauai.
The underwater lava tubes and caves create this magical underwater landscape.
I’ve seen sea turtles, tropical fish, and even monk seals here. The coral formations are stunning, and the water is incredibly clear when conditions are good.
Check ocean conditions before you go. If there are high surf warnings, skip it and head to the South Shore instead. Safety first, always.
9. Experience Makai Music & Arts Festival
Every Wednesday from 1:00 PM to 5:00 PM, the Princeville Makai Golf Club hosts this lovely local market.
You’ll find handmade jewelry, local art, and live music from some of Kauai’s best musicians.
Bring a lawn chair, grab something from the food vendors, and just relax. It’s free, family-friendly, and a great way to support local artists and businesses.
Plus, the setting overlooking the ocean is gorgeous.
10. Play Golf with Ocean Views
If you’re a golfer, Kauai’s courses are bucket-list worthy. The Poipu Bay Resort Golf Course and Hokuala Golf Course both offer stunning ocean views and challenging play.
Even if you’re not super into golf, these courses are beautiful places to spend a morning. Many offer food and drinks, so you can make it a leisurely experience.
January Events on Kauai
Pu’uwai Canoe Club Resolution Run (Early January)
This annual 5K run usually happens in early January at the Hokuala Resort. It’s a fun, family-friendly race that benefits the Pu’uwai Canoe Club and their youth programs.
Kids under 12 race free with a registered adult, and leashed dogs are welcome.
The course winds through beautiful trails with ocean views. Even if you’re not a runner, it’s a festive way to start the new year in Hawaii.
Makai Music & Arts Festival (Every Wednesday)
I mentioned this earlier, but it’s worth highlighting again.
Every Wednesday, you can catch local musicians, browse handmade crafts, and enjoy the aloha spirit at the Princeville Makai Golf Club. Free admission, and it’s a great afternoon activity.

Where to Stay in Kauai in January
The South Shore (Poipu area) tends to be drier in January, which makes it a solid choice for families. The North Shore is stunning but gets more rain. Personally, I love staying on the East Side in Kapaa because you’re centrally located and can easily access both sides of the island.
Browse hotels and compare prices on Expedia to find the best deals for your dates.
Your January Kauai Adventure Awaits
January in Kauai is special. You get whale season, gorgeous weather, fewer crowds, and that perfect mix of adventure and relaxation.
Whether you’re hiking to viewpoints, snorkeling with sea turtles, or just watching the sunset with a mai tai in hand, you’re going to make memories that last a lifetime.
My mother lives part-time on Kauai, and my grandmother spent years there before she passed. This island is woven into my family’s story, and I never get tired of returning.
There’s something magical about Kauai that keeps pulling you back.
Pack that light sweater, book your activities in advance, and get ready for an incredible January escape.
Mahalo for reading, and safe travels!
