SeaFest 2020

SeaFest showcases Ireland’s abundant maritime resources – raising awareness of the value and opportunities provided by the sea and also celebrates our proud maritime heritage.

SeaFest 2020 will take place in Cork on May 15 to May 17, 2020 and incorporates a series of marine-related business and research events, the annual Our Ocean Wealth Summit, as well as a maritime festival.

The Marine Institute co-ordinates SeaFest on behalf of the cross-government Marine Coordination Group, working together with a wide range of agencies and organisations.

What can you experience at SeaFest?

A weekend of fun, family friendly events lay in wait for you at SeaFest. Discover all about our oceans, including the creatures that live beneath, how we explore our seas, the ships that transport us and the fascinating tales from the deep.

Take part in interactive activities, watch demonstrations and go onboard a ship. The festival covers all things marine – from seafood cookery to science, cultural history to deep sea exploration and much more!

SeaFest has quickly become one of the most popular summer festivals in Ireland. The majority of events are free – however, a small number of events may require pre-booking for capacity reasons.

Why is SeaFest important?

SeaFest is a key part of Harnessing Our Ocean Wealth: An Integrated Marine Plan for Ireland (HOOW) and its goal of increasing participation and engagement with the sea.

Oceans flow over nearly three-quarters of our planet, and hold 97% of the planet’s water. They produce more than half of the oxygen in the atmosphere, and absorb the most carbon from it.

No matter how far from the shore that you live, oceans still affect your life and the lives of your families and friends, classmates and colleagues. For more information on the plan and on our oceans in general, visit
