The North Shore of Maui is a gently embayed coastal system with exposures to the northeast, north, and northwest. The shore is exposed to large swell during winter months, and short period, trade wind waves throughout the year.
The area has also experienced a history of tsunami inundation. The shoreline is dominated in the west by cobble and sand beaches, in the central region by lengths of sandy beach interrupted by engineered structures, and in the east by shorter lengths of sandy beach separated by rocky headlands.
