The buoy measures wave height, wave direction, wave period, and sea surface temperature. Scientists say the location off Hanalei is the best point in the Main Hawaiian Islands to capture the dominant big swell during winter seasons. Wave buoys stream data to inform safe transit and recreation and provide critical information for coastal hazard and low-lying inundation forecasts for north-facing shores.
“There are active fishing and recreational communities on Kaua‘i that rely on accurate ocean forecasts to know when conditions are safe, and having a wave buoy in this location will improve these forecasts,” explains Heather Kerkering, PacIOOS director. “Data are updated every 30 minutes and broadcast on the National Weather Service’s Marine Weather Channel.”
The buoy joins PacIOOS’ existing network of eleven real-time wave buoys in Hawai‘i, Guam, the Northern Mariana Islands, and the Marshall Islands. Data stream from the buoys to the PacIOOS Voyager (pacioos.org/
Based within the School of Ocean and Earth Science and Technology at the University of Hawai‘i at Mānoa, PacIOOS is the Pacific Islands regional component of the U.S. Integrated Ocean Observing System (IOOS®). PacIOOS is a partnership of data providers and users working together to enhance ocean observations and develop, disseminate, evaluate, and apply ocean data and information products designed to address the environmental, economic, and public safety needs of stakeholders who call the Pacific Islands home.
