World days, 8 Jun 2027

World Oceans Day

The United Nations day for the ocean, held on 8 June, with events at aquariums, beaches and reefs.

The idea of an ocean day was put forward at the Earth Summit in Rio de Janeiro in 1992, and the United Nations made 8 June World Oceans Day from 2009. Aquariums, schools and conservation groups use it to talk about overfishing, plastic, warming seas and coral bleaching, and about the marine protected areas where fishing is limited so that stocks can recover. Many of the events centre on fish that people know and like: sharks, rays, reef fish and the great migratory tunas.
