The PacIOOS wave buoy off Hanalei (CDIP #202; NDBC #51208) measures water temperature in the vicinity of Hanalei Bay at approximately 4 miles (6 km) offshore of Hāʻena Point on the North Shore of Kauaʻi in the State of Hawaiʻi. Data are transmitted every half hour. The temperature sensor is located at the base of the 0.9 meter spherical buoy, approximately 45 cm or 18 inches below the ocean surface.

The Hanalei Bay wave buoy is owned and managed by PacIOOS. The NOAA Coastal Storms Program (CSP) provided initial funding to purchase this buoy. Data are managed by the Coastal Data Information Program (CDIP) at Scripps Institution of Oceanography of the University of California, San Diego (UCSD). Long-term partnerships between PacIOOS, the U.S. Army Corps of Engineers (USACE), and CDIP enable data streaming into the PacIOOS website and PacIOOS Voyager.
