Oahu’s Whale Watching Season: When & Where to See Humpback Whales in Hawaii
Every year, one of nature’s most remarkable migrations takes place just off the shores of Oahu. From the depths of Alaska, thousands of humpback whales make their way to Hawaii’s warm waters to breed, calve, and rest. For visitors, this creates an extraordinary opportunity to observe these gentle giants up close.
If you’re planning a winter getaway to Hawaii, whale watching is one of the must-do experiences — and Oahu offers some of the best viewing locations in the islands.
When Do Whales Arrive in Oahu?
Humpback whales typically arrive in Hawaii around late November and stay through early April. The most active months tend to be:
- January
- February
- March
This is when whale sightings are incredibly common, often happening multiple times throughout a single tour. Mothers and newborn calves are especially active near the surface, making for unforgettable viewing.
Where Is the Best Place to Watch Whales on Oahu?
What makes Oahu unique is that whale-watching tours depart from both sides of the island:
✔ Ko Olina (West Oahu)
Calm waters and beautiful open-ocean views perfect for photography.
✔ Waikiki (South Shore)
Cityside departures with Diamond Head as the backdrop.
✔ Offshore Channels
Deep-water areas that attract whales for mating and breaching.
No matter where you stay, there’s a convenient spot to join a tour and enjoy prime whale activity.
