The Buzzards Bay Coalition is encouraging swimmers to set a goal to swim for clean water this summer. The 25th anniversary of the Buzzards Bay Swim will be held on June 30. Registration is open now at www.savebuzzardsbay.org/swim.

With more than 150 swimmers and a dozen teams already signed up, organizers said this year’s swim may be the biggest in the event’s history.

Swimmers will complete a 1.2-mile point-to-point open-water course starting in New Bedford’s South End, past the Butler Flats Lighthouse and New Bedford hurricane barrier.

At the finish line at Fort Phoenix State Reservation in Fairhaven, swimmers and their guests will be welcomed with a beach party featuring a live steel drum band, pancakes cooked to order, gourmet coffee, free massages, local craft beer and awards and prizes.

Since the first Buzzards Bay Swim in 1994, the event has grown to attract more than 300 swimmers from communities across New England and beyond to the shores of New Bedford and Fairhaven each June. The swim welcomes swimmers of all abilities and fitness levels ages 11 and up.

Prizes are awarded for the top fundraisers and fastest swimmers, both individuals and teams.

Swimmers who have participated in the swim for five, 10 and 20 years will also receive special participation awards.

First-time and beginner swimmers can have a personal kayak or paddleboard safety escort, as well as choose to use swim aids such as fins or snorkels.

Many swimmers recruit friends and form a team to swim across the harbor together. This year, teams such as “The Cape Crusaders,” “Finding Dory” and several local YMCA teams are already training and fundraising.

All funds raised through the swim support the Buzzard Bay Coalition’s work to protect clean water in communities across the Buzzards Bay region.
