Hawaiian Islands Humpback Whale National Marine Sanctuary

Every winter, thousands of humpback whales travel to the warm, shallow waters of Hawai‘i to mate, give birth, and raise their young. Hawaiian Islands Humpback Whale National Marine Sanctuary protects these whales and their habitat. From November through April, visitors to the sanctuary can see whales from shore and at sea.

Whale Protection

More than half of the humpback whales in the North Pacific seasonally use the waters around the Hawaiian Islands as their principal breeding and calving wintering ground. The sanctuary's mission is to protect Hawai‘i humpback whales and this extremely important habitat through closely aligned education, research, and resource protection efforts. The sanctuary works with the community and our other partners to reduce threats to humpback whales, including through enforcement.

Native Hawaiian Heritage

Ocean stewardship is deeply embedded in Native Hawaiian culture. Humpback whales, or koholā, are an important part of history, legends, and connection to the sea. The cultural and maritime heritage of Hawai‘i plays a role in management decisions and how the sanctuary's daily activities are carried out.
