Festuca occidentalis is a tufted fescue that lacks rhizomes. The smooth and shiny culms are  tall. Culms have two exposed nodes and have glabrous internodes. The shoots are intravaginal. The leaf sheaths are glabrescent and rounded with a prominent midvein. The position of the auricle is marked by a distinct swelling. The minutely erose ligule is  long. The basal leaves are capillary and  long. In cross section, the leaf blades are  wide and  thick, with three large veins and one to five ribs. The basal offshoots are erect, arising from the tops of the pale brown sheaths. The lax, subsecund, flexuous panicle is  long. The panicle has two unequal and strongly reflexed branches at the lower node, with branches  long bearing minute trichomes. The three to five flowered spikelets are  long. The rachilla is visible at anthesis and internodes are  long. The unequal glumes are narrow and acute. The lower glume is  long with one vein, and the upper glume is  long with one to two veins. The membranaceous, oblong to lanceolate lemmas are  long, with slender, flexuous awns  long. Paleas have inflexed sides that meet in the middle, measuring  long.
