The Washington State Open has been an integral part of Seattle Tennis Club since the inception of both institutions in 1890. Now in their 129th year together, Washington State Open and Seattle Tennis Club are excited to welcome the USTA, fans, staff, and athletes back once again for the Pacific Northwest's flagship tennis event. In 1950, what was already a thrilling week of tennis was forever changed when Seafair joined the Seattle event landscape. The Washington State Open takes place simultaneously with Seafair Weekend, offering unparalleled views of the Boeing Seafair Air Show from our lakefront location.
