Queensland's Gold Coast is Australia's most visited stretch of coastline and the justifiably famous right point-breaks can get crowded especially at Kirra and Snapper Rocks. However away from 'Surfers' Paradise' and the further north you travel up the 'Sunshine Coast' the crowds thin but other factors such as hazardous wildlife start to become a factor before the fickle Great Barrier reef starts to block incoming swells from the mainland. Facing east before progressively sloping west, the coastline below this reef picks up any east swells and some north-easterly during summer, including cyclone swells. Southerly winds dominate except for during the summer when they swing northerly. Water temperatures are sub-tropical, ranging from 19-25°C or 66-77°F. Introduced to the area by local lifeguards in the 1920s, the local surfing population now exceeds 100,000.
