An extendable windshield wiper system includes a wiper blade assembly having: a resilient material wiper blade; and a wiper extension rod connected to the wiper blade. A wiper sleeve is configured to move about an arc of rotation with respect to an axis of rotation of the wiper sleeve. A bore of the wiper sleeve has the wiper extension rod slidably disposed within the bore. An actuation portion directs a pressurized fluid to outwardly extend the wiper extension rod from the wiper sleeve and thereby to outwardly extend the wiper blade in an extension direction during a first portion of the arc of rotation. The wiper blade is induced to traverse an extended arc of travel during rotation of the wiper extension rod and the wiper sleeve along the arc of rotation.
