As the wave passes over the shallow area its shape is raised and steepened, creating a localised wave formation. The size and shape of bombora waves makes them attractive to surfers willing to take the risk of riding what is generally considered a hazardous pursuit.
These formations can pose a significant danger even in good weather as a bombora may not be identifiable because it may not always have breaking waves.
The term bombora was given wide circulation in 2009 on ABC TV with the airing of a documentary that received a nomination for the 2010 Logie Awards in Australia.[full citation needed] The documentary explored historical dimensions of the relationship between surf culture and Australian cultural identity.
"Bombora" is also the title of a popular music instrumental released in 1963 by Australian surf rock band The Atlantics.
The term bombora is also used for a sketchy surf spot where waves seem to break on the outside.
