Wave-cut platforms are a common coastal feature found on the island of Oahu in Hawaii. These flat, rocky surfaces are formed by the constant erosion of waves crashing against the shoreline.

Locations of Wave-Cut Platforms on Oahu

There are several locations on Oahu where you can see wave-cut platforms:

• Makapu’u Beach: Located on the eastern side of the island, Makapu’u Beach is known for its stunning views and rocky coastline. The wave-cut platform here is easily accessible and provides a great spot for fishing and exploring tide pools.
• Waimea Bay: This popular surfing spot on the North Shore of Oahu also has a wave-cut platform that can be seen at low tide. The platform is made up of lava rock and is a great place to watch the waves and take in the scenery.
• Halona Cove: This small cove on the southeastern side of the island is known for its beautiful beach and clear waters. The wave-cut platform here is located just offshore and can be seen from the beach.
• Kaena Point: Located on the westernmost tip of Oahu, Kaena Point is a remote and rugged area with a wave-cut platform that can be seen from the hiking trail that leads to the point.

How Wave-Cut Platforms are Formed

Wave-cut platforms are formed through a process called marine erosion. As waves crash against the shoreline, they wear away the rock and sediment, creating a flat surface. Over time, this surface can become quite large and can be seen at low tide when the water recedes.

Wave-cut platforms are not only interesting to look at, but they also provide important habitats for marine life. Many species of plants and animals can be found living on these rocky surfaces, making them an important part of the coastal ecosystem.
