Surfing was popularised in Cornwall during the late 20th century, and has since become readily associated with Cornishness. The waves around the Cornish coastline are created by low pressure systems from the Atlantic Ocean which unleash powerful swells eastwards creating multiple, excellent surfing conditions around Cornwall. Newquay, one of Britain's "premier surfing towns", regularly hosts world championship surfing events. Surfing in particular is very popular, as locations such as Bude and Newquay offer some of the best surf in the UK. On 2 September 2007, 300 surfers arrived at Polzeath beach, Cornwall to set a new world record for the highest number of surfers riding the same wave (as part of the Global Surf Challenge and part of a project called Earthwave to raise awareness about global warming).
