Whale Watching Tours in Oahu

Every winter approximately 10,000 to 12,000 humpback whales travel to Hawaii from Alaska to Hawaii during their mating and calving season, and from November to May, you will often see these massive marine mammals in the warm waters surrounding the islands of Hawaii.

Although the protected oceanic areas known as the Humpback Whale National Marine Sanctuary are mainly found between the islands of Maui, Molokai and Lanai, the island of Oahu is also a popular destination for humpback whales, and they can be found off the shores of Waikiki, the North Shore, and both the east (windward) and west (leeward) side of the island.

Oahu whale watching tours are available for only a limited amount of time, and should not be missed by anyone on the island during the winter whale watching season.

More details can be found in our Hawaii Whale Watching Guide!

• Humpback whales travel annually between Hawaii and Alaska to both give birth and raise their young in the warm waters off the islands of Hawaii. Once the calves have become bigger and stronger, the humpback whale pods return to Alaska for spring and summer.
• Adult humpback whales do not eat while they are in Hawaii, and female humpback whales expend tons of energy feeding their calf during their Hawaiian visit.
• Humpback whales spend most of their time underwater, but stay on and just below the ocean’s surface for approximately 15 minutes. If they are feeling energetic, you can sometimes see them jump or breach out of the water, and even slap their tails and fins on the water.
• You will want to catch sight of humpback whales as quickly as possible once they surface since they can stay underwater for up to an hour with lungs as large as a small car.
• Once a humpback whale calf is born, they gain around 100 lbs a day while their mothers nurse them, and marine biologists and ocean conservationists track the calve’s progress before they head back to Alaska.
• While humpback whale calves grow exponentially while in Hawaii, adult humpback whales are quite the opposite. They will normally lose around 25% of their body weight during their stay in Hawaii, and need to return to Alaska to feed.
• Many Oahu whale watching cruise boats come equipped with hydrophones which will allow you to hear the famous whale songs of the humpback whales. Male humpback whales all sing the same complex whale song throughout the season, and then pick-up the following season where the previous song left off.
• While beautiful whale songs are special in their own way, scientists do not have a definitive reason as to why the humpback whales sing, but it is said that whales sing to communicate, locate food, and find each other.

• Guests who are prone to motion sickness should plan on taking a motion sickness preventative at least one hour prior to departure.
• Many of the top Oahu whale watching tours book up days or weeks in advance. Be sure to book whale watching tours as early as possible to ensure a spot on the boat.
• Keep an eye out for the following humpback whale behaviors on Oahu: A spout of water from the blowhole which will look like a spray from the ocean’s surface, whale tails or fins coming up from the water, or an epic partial or full breech where they will propel themselves out of the water to belly flop onto the surface.
• Be patient during your Oahu whale watching cruise, and keep your eye out for irregularities on the water. You will never know when humpback whales will make their presence known, and if the humpback whales do not make an appearance during your cruise, enjoy your time in Hawaii’s waters.
• Federal laws require that all boats and persons stay at least 100 yards away from humpback whales at all times. Sometimes whales become curious and will swim to a boat, and the boats are required to turn off their engines and wait till the humpback whale moves away.
• The best time for whale watching Oahu tours is often during the morning and afternoon since the ocean and winds are much calmer at this time. This is not to say that humpback whales cannot be seen during dusk and sunset, and depending on how active the calves are, they can be quite playful throughout the day.
