Whale watching season in Oahu runs from November through April, when thousands of humpback whales come to Hawaii’s warm waters to mate, give birth and raise their calves. Sightings are most reliable in mid-winter. You can see whales from shore at high coastal viewpoints such as Makapuʻu Point, the Diamond Head summit and the southeast coast around Halona, or get closer on a licensed whale-watching boat.
Here’s when to go, where to look, and how to watch responsibly.
When is whale season on Oahu?
NOAA’s Hawaiian Islands Humpback Whale National Marine Sanctuary says visitors can see whales from November through April.
- November and early December: the first whales arrive. Sightings are possible but less frequent.
- Mid-winter: the most reliable months, with the most whales in Hawaiian waters.
- March and April: sightings taper off as whales begin the long journey north.
If whales are high on your list, plan your trip for mid-winter, and treat the months either side as a bonus.
Why humpbacks come to Hawaii
Each winter, humpback whales, known in Hawaiian as koholā, travel from their feeding grounds in the cold waters of the North Pacific to the warm, shallow waters around the Hawaiian Islands. They come to breed, to give birth and to nurse their calves, not to feed.
That’s why you’ll often see mothers with young calves close to shore, and why you might see dramatic behavior such as males competing for females. It’s also why these waters are protected as a national marine sanctuary.
Where to see whales from shore on Oahu
You don’t need a boat. Height and a clear view of open ocean are what matter.
Makapuʻu Point. At the southeastern tip of Oahu, the paved Makapuʻu Point Lighthouse Trail, about two miles round trip, climbs to lookouts over the open channel. It’s one of the island’s classic winter whale-watching spots. Bring water and a hat, because there’s no shade.
Diamond Head summit. Hawaii State Parks notes that humpback whales can sometimes be seen from the summit in winter. You’ll need a reservation for the hike. Our guide to Diamond Head tickets and timing explains how to get one.
The southeast coast around Halona. The coastline between Hanauma Bay and Makapuʻu faces open water, and the lookouts along it are good places to scan for spouts.
The North and West Shores. Whales are seen off other coasts too, especially from higher ground, although the southeast is usually the most dependable.
How to spot a whale
- Look for the blow. A spout of misty air shooting a few feet up is usually the first thing you’ll see.
- Scan slowly, from the shoreline out to the horizon, rather than staring at one spot.
- Watch for splashes. Breaches, tail slaps and fin slaps throw up white water you can see from far away.
- Bring binoculars if you have them.
- Go in the morning, when the water is often calmer and splashes are easier to see.
- Be patient. Whales can stay under for many minutes. Where you’ve seen one, you’ll often see more.
What you might see
- The blow: the misty spout from a whale breathing out at the surface, often the first sign one is there.
- A breach: a whale launching most of its body out of the water and crashing back down. It’s the sighting everyone hopes for.
- Tail and fin slaps: a whale slapping its tail or long pectoral fin on the water, sending up spray you can see from far away.
- A fluke: the tail lifting clear of the water as a whale dives, often the last you’ll see of it for a while.
- Mothers and calves: a large whale and a small one surfacing together, often in calmer water closer to shore.
Whale-watching boat tours
For a closer look, licensed boat tours run from Honolulu harbors and the west side during the season. Choose an operator that follows the federal approach rules and doesn’t promise close encounters. If you’re prone to seasickness, take a remedy before you board, and choose a morning trip, when seas are usually calmer.
The rules: how close can you get?
Humpback whales are protected, and federal law sets clear limits in Hawaii:
- Stay at least 100 yards away from humpback whales, on a boat, kayak or paddleboard, or in the water.
- Aircraft must stay at least 1,000 feet away. If you fly a drone near the ocean, keep well clear of whales.
- Never chase, surround or cut off a whale’s path. If a whale approaches you, stay still or move away slowly.
These rules protect mothers and calves resting close to shore, and they keep you safe too. A 40-ton animal is not something to crowd.
Help count the whales
For 30 years, the sanctuary’s Sanctuary Ocean Count has brought volunteers to shore sites around the islands on winter mornings to count humpbacks and record their behavior. It’s a good way to spend a morning if you’re in Hawaii at the right time. Details are on the sanctuary’s website.
Seeing whales on the circle island tour
Between November and April, our full-day circle island tour begins along the coast where whales are often seen. The first two stops, the Diamond Head Lookout and Halona Blowhole, both look out over open ocean, so keep your eyes on the water. Whales are wild and there’s never a guarantee, but a spout on the horizon is a real possibility on a winter morning.
Later in the day, winter brings big waves to the North Shore, and our guide to Waimea Bay, Laniakea and Sunset Beach explains where to watch them.
Winter on Oahu, from the southeast coast to the North Shore. Our full-day circle island tour starts at two ocean-facing lookouts and covers nine stops in about 9.5 hours. The Standard tour is $59. Check dates and book
