Humpback Whale Behaviors Explained: Breaches, Spouts, and Songs
Reading the Language of the Whales

Part of what makes whale watching on Oahu so thrilling is that humpback whales are wonderfully active at the surface. They leap, slap, spout, and even sing, and each of these behaviors tells a little story. Knowing what you are seeing turns a good whale watch into a great one. Here is a guide to the most common humpback whale behaviors and what they might mean.

The Spout, or Blow

The first sign of a whale is usually its spout, the misty cloud that shoots up when a humpback exhales at the surface. This blow can rise several feet into the air and is often visible from far away, making it the easiest way to spot a whale. A humpback surfaces to breathe every few minutes, so watching for that telltale puff of mist is how most sightings begin.

Breaching: The Big Leap

The most spectacular behavior of all is the breach, when a humpback launches much of its massive body out of the water and crashes back down in an explosion of spray. For an animal that can weigh 40 tons, it is a jaw-dropping sight. Scientists are not entirely sure why whales breach, and the possible reasons only add to the wonder.
- To communicate with other whales through the huge splash.
- To shake off skin parasites.
- Or perhaps simply for play.
Whatever the reason, catching a full breach is the moment every whale watcher hopes for.

Tail and Fin Slaps

Humpbacks often slap the surface with their tails or their long pectoral fins, creating a loud smack that carries across the water. A tail slap, sometimes called lobtailing, and a pectoral slap are thought to be forms of communication, or a way to signal excitement or warning. When you see a whale repeatedly slapping the water, you are watching it send a message.

The Fluke and the Dive

When a humpback lifts its tail, or fluke, high into the air, it is usually about to make a deeper dive. This graceful move, called fluking, is a favorite of photographers, since the underside of each whale’s tail has a unique pattern that researchers use to tell individuals apart. A raised fluke is a beautiful goodbye as the whale slips below the surface.

The Song of the Humpback

Perhaps the most magical behavior of all cannot be seen, only heard. Male humpbacks are famous for their long, complex songs, which they sing in Hawaiian waters during the winter breeding season. These haunting sounds can travel for miles underwater, and on a quiet boat you may even feel them through the hull. It is one of nature’s most mysterious performances.

Watch the Show Unfold

From the first misty spout to a thundering breach, a slap of the tail, or the raised fluke of a diving whale, every humpback behavior is a window into these gentle giants. The next time you head out on an Oahu whale watching tour, keep your eyes on the water and you will start to read their language. Watch respectfully from a distance, and let the humpbacks put on a show you will never forget.

What to Bring Whale Watching on Oahu
Pack Right for a Day on the Water

A whale watching tour on Oahu is an unforgettable experience, and packing the right things helps you stay comfortable so you can focus on the whales. You will be out on the open ocean for a couple of hours, often in the cooler winter months of whale season, so a little preparation goes a long way. Here is exactly what to bring on your Oahu whale watching tour.

Dress in Warm Layers

This is the tip that surprises the most people. Even in sunny Hawaii, it can feel cool and breezy out on the open water, especially with the wind and spray, and whale season falls in the cooler part of the year. The trick is to dress in layers you can add or remove.
- A windbreaker or light jacket to block the wind and spray.
- A warm layer underneath for the breeze offshore.
- Long pants or a light layer over your legs for comfort.
You can always take a layer off if the sun warms you up, but you cannot add one you did not bring.

Sun Protection Still Matters

Even on a cool, breezy day, the Hawaiian sun is strong and reflects off the water from every angle. Bring reef-safe sunscreen to protect your skin and the ocean the whales call home, along with sunglasses and a hat. It is easy to underestimate the sun when the wind keeps you cool, so apply and reapply throughout the trip.

Gear to See the Whales

A few items make spotting whales far more rewarding. Binoculars are wonderful for getting a closer look at spouts and distant breaches, and a camera with a good zoom lens helps you capture the action, since boats keep a respectful distance from the whales. Keep your camera secured with a strap, and consider a waterproof pouch to protect it from spray. Watching a whale leap through a good lens is a memory you will treasure.

Comfort Essentials

Finally, pack a few things to keep you comfortable for the whole trip. Bring water to stay hydrated and a small snack for energy. Most importantly, if you are at all prone to motion sickness, take a remedy or some ginger candies before you board, since the open ocean can be bumpier than the calm shore. Feeling good keeps your eyes on the horizon instead of the rail.

Ready to Meet the Whales

With warm layers, sun protection, binoculars and a camera, and a few comfort essentials, you are all set for a wonderful day of whale watching on Oahu. Dress for the cool ocean breeze, protect your skin, and keep a motion-sickness remedy handy. Do that, and all that is left is to watch the horizon for that first misty spout and the giant that follows it.

Whale Watching on Oahu: A Guide to Humpback Whale Season
Hawaii’s Greatest Winter Show

Every winter, thousands of humpback whales leave the cold waters of Alaska and swim all the way to Hawaii, and Oahu offers a front-row seat. There is nothing quite like watching a 40-ton whale launch itself clear out of the ocean, then land with a thunderous splash. If a Hawaii trip is in your future, here is everything you need to know about whale watching on Oahu, from when to come to how to do it right.

When Is Whale Season on Oahu?

Oahu’s whale season runs roughly from November through May, with the peak stretch from January into March. That is when the most humpback whales, known in Hawaiian as kohola, are gathered in island waters. Whale watching tours generally sail throughout the season, and if you visit during the peak months, your chances of a sighting are excellent.

Why the Whales Come to Hawaii

The humpbacks make one of the longest migrations of any mammal, traveling thousands of miles from their Alaskan feeding grounds to Hawaii’s warm, shallow, sheltered waters. They come here not to eat, since they mostly fast during their stay, but to mate, give birth, and nurse their young. These waters are so important that they are protected as the Hawaiian Islands Humpback Whale National Marine Sanctuary, a reminder of just how special this seasonal gathering is.

What You Will See

Humpbacks are among the most active and acrobatic of all whales, and part of the thrill is never knowing what they will do next. Keep your eyes on the water for these classic behaviors.
- Spouts, the misty blows you can spot from far away.
- Breaching, when a whale leaps almost fully out of the sea.
- Tail and pectoral fin slaps against the surface.
- Mothers gliding alongside their newborn calves.
Male humpbacks are also famous for their long, haunting songs, and on a quiet boat you may even feel the ocean carry that sound.

Where and How to Watch on Oahu

You can sometimes catch a distant spout from shore at spots like Diamond Head or the Makapuu Lighthouse lookout, but the best way to experience the whales is from the water. A whale watching tour takes you out to where the humpbacks gather, usually sailing from the Waikiki and Honolulu area, and gets you far closer to the action than any overlook. As a local curator of these tours, we help match you with the right boat and departure for your group.

Whale Watching the Responsible Way

These whales are protected, and giving them room keeps everyone safe. In Hawaii, federal law requires boats and people to stay at least 100 yards away from humpback whales. Responsible captains cut their engines and let the whales set the pace, and they never chase or crowd them. Now and then a curious whale will approach a boat on its own, which is an unforgettable gift, but the rule is always to let the whale come to you.

Tips for the Best Trip

A little planning makes a whale watching morning even better. Mornings often bring the calmest seas, so an early tour can mean a smoother ride and better viewing.
- Dress in layers with a windbreaker, since it is breezy on the water.
- Bring sunscreen, sunglasses, and a camera or zoom lens.
- Take a motion-sickness remedy beforehand if you are prone to it.
- Pack a little patience, since these are wild animals worth the wait.
Sightings are common in peak season, and many operators are so confident that they offer a sighting guarantee, so ask about that when you book.

Come Meet the Kohola

Whale watching on Oahu is one of the most awe-inspiring experiences Hawaii has to offer, a chance to share the water with gentle giants who traveled thousands of miles to be here. Visit between November and May, head out with a respectful tour, keep your distance, and get ready for the moment a humpback rises from the sea. It is a memory that will stay with you long after you leave the islands.
