The Nam O Cau Ngu Festival originated hundreds of years ago, closely linked to the formation and development of Nam O fishing village, one of the oldest coastal villages in Da Nang. According to historical records and elders' accounts, the festival was established in the 17th century when the first residents from Quang Nam migrated to this land to settle and make a living from fishing.
Amidst the vast ocean, where every sea trip carries inherent dangers, the people of Nam O formed the Cau Ngu ritual as part of their belief in worshipping Ca Ong (whales). They believe that Ca Ong is the guardian deity of the sea, protecting fishermen through big waves and violent storms, bringing bumper fish catches and peace to the community.

In 2017, the Nam O Cau Ngu Festival was recognized by the Ministry of Culture, Sports and Tourism as a National Intangible Cultural Heritage. This event not only affirms the festival's historical and spiritual values, but also opens up opportunities to preserve and promote marine cultural heritage amidst Da Nang's rapid urbanization. To date, the festival is regularly held from the 13th to 15th day of the second lunar month (usually falling in late March or early April in the Gregorian calendar), attracting thousands of tourists and locals to attend and immerse themselves in the sacred and bustling atmosphere of the Nam O coastal village.
