Set on Lake Washington's 1.5 miles of shoreline, the Seafair Weekend Festival is the largest boating event, air show, and festival all rolled into one! Fans enjoy the Boeing Seafair Air Show featuring the U.S. Navy Blue Angels, the HomeStreet Bank Cup with 220MPH H1 Unlimited hydroplane racing, and the unforgettable sights, sounds, and smells of Alaska Airlines Park. Culminating the iconic, summer-long Seattle Celebration and known and loved as an unofficial Puget Sound holiday, this is the most anticipated event of the summer!
