Saturday 12th September 2026
11:00 – 14:00
Entry is by qualification only through the Leinster Open Sea calendar, making it one of the hardest open water entries to secure in the country.
For over a century, The Dublin City Liffey Swim has been the pinnacle of the open sea season.
This historic event provides an unforgettable experience for competitors and spectators. The swim starts at Rory O’More Bridge near Guinness Brewery gate and ends at North Wall Quay famously standing before The Custom House, passing under eleven bridges along the route, including landmarks like the Four Courts.
The Liffey is a tidal river, and the swim is timed to coincide with the incoming tide to give swimmers an assist. Water temperature in September is typically 13–15°C.
Swim Ireland are delighted to once again be hosting this historical event on Saturday 12th September 2026 with a prize giving at Custom House Quay afterwards.
