West Seattle Polar Plunge 2025. Celebrate new year's day with a fun 5k with zona dos run club run followed by a refreshing polar plunge at alki beach! The new year polar bear plunge is back for 2025.

The dip in the water is at noon sharp, but come early to sign up. It was as much shrieking as swimming when more than a thousand people ran into and out of puget sound along alki beach this morning during the 2025 edition of the west seattle new year’s day.
