Lake Sammamish borders Redmond's western edge, while the city of 73,000 extends eastward onto the plateau between Seattle and the Cascade foothills. The Sammamish River flows north through central Redmond, creating a natural corridor through the urban landscape. Pacific Northwest maritime climate brings mild, very wet winters averaging in the low 40s and dry summers reaching the mid-70s. Redmond sits at roughly 100 feet elevation, part of the greater Seattle metropolitan area. Corporate campuses occupy significant portions of the city, interspersed with residential neighborhoods and preserved greenspaces.
