Great Whale Count

The annual Great Whale Count, part of Maui Whale Festival, brings volunteers together to count whales from shore as part of a long-term survey of humpback whales in Hawai‘i. This event provides a snapshot of trends in relative abundance of whales and is one of the world’s longest-running community scientist projects.

Mahalo to everyone who participated in 2022’s Great Whale Count! View results below.

Since 2019, the Hawaiian Islands Humpback Whale National Marine Sanctuary’s Ocean Count and Pacific Whale Foundation’s Great Whale Count have been conducted on the same days in January, February, and March, to collect data on whales from all the main Hawaiian Islands simultaneously. You can find the latest stats from both counts below.
