The prolonged westward track of Hurricane Fefa produced swells of up to 15 feet (4.5 m) in height. The swells hit eastward facing beaches along the island of Hawaii. The swells washed debris and sea water onto coastal roads near Punaluu Black Sand Beach, resulting in the roads being closed following the storm. Southwestern Maui experienced rough surf, as well. Despite being a weak tropical depression and a tropical wave while moving through the Hawaiian Islands, Fefa produced locally strong wind gusts of up to 50 mph (80 km/h) in the islands of Hawaii and Maui.
