Get ready to make waves, Eastie! The 15th annual Shamrock Splash is back at Constitution Beach, and it’s your chance to take a freezing but fun dive into Boston Harbor—all for a great cause.

On Sunday, March 2nd, from 11 AM – 2 PM, brave souls will be plunging into the (very cold) water to support Save the Harbor’s Better Beaches Grant Program, which helps fund free beach events and programs for the community. And don’t worry—it’s not just about the splash! There will be a costume competition, so bring your best themed look, plus plenty of warm food and drinks to help you defrost afterward.

Whether you’re jumping in or just cheering from the shore, it’s a great way to support our local beaches while having an absolute blast. Ready to take the plunge? Register here
