This year, we’re celebrating our 21st annual Polar Bear Plunge to "Keep Winter Cold!" Every winter for the past 20 years, hundreds of passionate climate activists have dashed into icy cold waters for a winter swim to raise funds in support of the work of the Chesapeake Climate Action Network (CCAN). Just like a charity fun run, Plunge participants accept donations from their friends and family to support our vital climate work!
All Plungers are invited to join us for a morning of fun on February 7, 2026 to plunge in person at the National Harbor on the banks of the Potomac River.
