Independence from the Ocean Count program

This site is not affiliated with NOAA or with the sanctuary’s Ocean Count program. Registration and official results come only from the program’s own site, oceancount.org. We compile the published results across years and add notes on shore spots for watching whales.

About the Sanctuary Ocean Count

NOAA’s Hawaiian Islands Humpback Whale National Marine Sanctuary has run the Ocean Count since 1996. On the last Saturday of January, February and March, volunteers at shore sites count humpback whales from 8 am to 12:15 pm and record the whales’ surface behavior. On Maui and Lānaʻi, the Pacific Whale Foundation runs its own Great Whale Count on the same days.
