Abstract: An omnidirectional wind indicator. An elongated mast is rotatable about its axis with respect to a base support. The mast is of tapered design and flexible, resilient composition with flexibility increasing with distance above the base support. A three-sided flag includes a curvilinear leading edge. A sleeve is formed along the curvilinear edge for receiving the mast. When inserted, the upper end of the mast follows the curvilinear shape of the sleeve. The resulting configuration spring-loads the flexible upper portion of the mast to maintain the flag in taut alignment. Wind velocity is indicated by tails sewn to the trailing edge of the flag and by wings pivotally mounted transverse to the plane of the flag.
