It’s icy, frosty and just plain cold: it’s Renton’s Polar Bear Plunge. This annual New Year’s Day tradition at Gene Coulon Park will start your 2025 with a jolt!

Renton’s Polar Bear Plunge is at 10 a.m. on January 1, 2025. It’s free to participate, but you need to pre-register. 

The goal is simple: make a run into the chilly waters of Lake Washington – and run back out as fast as you can. Expect the water to be about 45- to 47-degrees. Sometimes, it feels colder because of the wind. The crowd will cheer you on as you immerse yourself in Lake Washington – or just dip your toes. Either way, it’s a fun-filled morning that’s guaranteed to wake you up.


Renton hosted its first Polar Bear Plunge in 2008. Ever since, residents and visitors alike have made it a tradition to take a dip in Lake Washington on New Year’s Day.
