Aganoa Beach: Aganoa Beach is situated on the east coast of Savai'i island in Samoa.  The waters off the beach are a known surf reef break in the region and were the venue for the surfing competition at the 2007 South Pacific Games.  The left and right breaks are paddling distance from the beach.

Multi-purpose reef: A multi-purpose reef, also commonly known as an artificial surfing reef or surf reef, is a structure located offshore designed to induce wave breaking in a manner that creates a wave suitable for surfing or body boarding.  Artificial surfing reefs can exist in many different configurations and be built from a variety of different materials.  To date there have been fewer than ten attempts to build such a structure worldwide.

Swami's: Swami's, also known as "Swami’s Reef'" and "Swamis", is an internationally known surfing spot, a point break located in Encinitas, San Diego County, California.  Swami's was named after Swami Paramahansa Yogananda, because the grounds and hermitage of the Self-Realization Fellowship ashram, built in 1937, overlook this reef point.  The name "Swami's" is also given to the sand beach that extends south from the point to the next beach access point, which is next to the San Elijo State Beach camping area; this more southerly surf spot often goes by the name "Pipes".

Carol Philips: Carol Philips (born 1966) is a pioneer of big-wave bodyboarding for women.  She was the first woman to compete against the men at the Banzai Pipeline on the North Shore (Oʻ ahu).  She founded the World Championship of Women's Bodyboarding in memory of Don and Josie Over in 1990.  She was the first woman to hold a permit to run a contest at the Banzai Pipeline.  Philips is the founder of the North Shore Surf Girls - Surf School.

Banzai Pipeline: The Banzai Pipeline, or simply "Pipeline" or "Pipe," is a surf reef break located in Hawaii, off Ehukai Beach Park in Pupukea on O'ahu's North Shore.  A reef break is an area in the ocean where waves start to break once they reach the shallows of a reef.  Pipeline is notorious for huge waves which break in shallow water just above a sharp and cavernous reef, forming large, hollow, thick curls of water that surfers can tube ride.  There are three reefs at Pipeline in progressively deeper water further out to sea that activate according to the increasing size of approaching ocean swells.

Nelscott Reef: Nelscott Reef is an ocean reef near Lincoln City, Oregon, United States, that creates a reef break (a surf-break created by the presence of a rock or coral reef) that is known as the only place on the Oregon Coast with the right conditions for big wave surfing.  It is named for the former community of Nelscott, which is now a part of Lincoln City.  It is the venue of the Nelscott Reef Surfing Pro-Am Event held annually since 2005, and founded by local surfer Adam Wagner and Gabe Smith.

Al Gal: Al Gal is a beach area located on the west coast of Israel near the city of Bat Yam.  It is an exposed beach break and reef break that has fairly consistent surf, specially during the months of summer when most of the surf comes in the form of wind waves.

Surf break: A surf break (also break, shore break, or big wave break) is a permanent (or semi permanent) obstruction such as a coral reef, rock, shoal, or headland that causes a wave to break, forming a barreling wave or other wave that can be surfed, before it eventually collapses.  The topography of the seabed determines the shape of the wave and type of break.  Since shoals can change size and location, affecting the break, it takes commitment and skill to find good breaks.  Some surf breaks are quite dangerous, since the surfer can collide with a reef or rocks below the water.

Ruggles Avenue Surf Break: The Ruggles Avenue Surf Break is the premier East Coast big wave surf break.  Located at the eastern end of Ruggles Avenue in Newport, Rhode Island, the rocky reef break features three distinct breaks: "The Point" "Out Front" and "Around the Corner", each of which presents different challenges, and becomes active during different weather patterns.
