Who we are
Built by players, for players — nearly 100,000 square feet of indoor pickleball near Seattle's Mount Baker neighborhood.
Sideout Tsunami was founded by veteran players and coaches from the Puget Sound community, and is independently owned and operated as part of the Side Out family. Twenty-six professional-grade indoor courts, three of them championship courts and open year-round.
We are also the official home of the Seattle Tsunami, a founding franchise of the National Pickleball League.
While anyone is welcome to walk in and play, becoming a member unlocks exclusive savings on court fees and priority court reservations so you can secure your spot ahead of time.
At Side Out Tsunami Pickleball Center, our mission is to create an environment that welcomes everyone at all skill levels with friendly competition, respect for each other and to build connections both on and off the court.
