Baltic Sea Day

Baltic Sea Day

Baltic Sea Day was celebrated on 28 August. We are responsible for both coordinating international celebrations and organising our own events throughout the day.

In 2025

• We inspired several cities and other maritime operators to get involved. About 160 events and activities were listed on the Baltic Sea Day website. The largest events were held in Hanko (City of Hanko and its partners), Turku (The Baltic Sea Challenge), and Helsinki (John Nurminen Foundation).
• In Helsinki, we organised and coordinated the Baltic Sea Festival – a joint event involving several environmental and cultural organisations – at Kansalaistori Square and on Pakkahuoneenlaituri Quay. 31 organisations participated, and about 3,300 visitors attended the event.
• We also organised The Plunge on Hietalahti Beach, guided tours of our Maritime Museum, Baltic Sea morning coffee meetings for companies, and a culture-themed discussion at Helsinki Art Museum. Our experts participated in events arranged by other organisations.
• We were in charge of marketing and joint media appearances. Baltic Sea Day got about 120 news hits.
• A significant portion of the celebrations took place on Baltic Sea Day’s social media, which was managed by the Foundation. Our Baltic Sea Day content on Instagram reached more than 200,000 accounts during the last few days of August.
• We helped our international partners to organise their Baltic Sea Day events.

Our partners included:
Race for the Baltic (Sweden), Voice of the Ocean (Sweden), the Finnish Institute in Estonia (Estonia), City of Hanko, Baltic Sea Challenge (Turku), Finnish Nature League, Finnish Environment Institute, Finnish Swimming Teaching and Lifesaving Federation, Aquatics Finland, Helsingin Sanomat, JCDecaux, Sponda Shopping Centres, and HAM Helsinki Art Museum.
