A wind indicator is described that includes a body with a frame including a spindle axis and a web. A pivot is connected to the frame to permit the body to rotate about a pivot axis. A spindle is disposed on the spindle axis and is rotatable about the spindle axis. The spindle includes first and second hubs, each of which include a central body portion and at least one vane support receiving element. The wind indicator also has at least one element connecting the first hub to the second hub to maintain the first and second hubs in positional relation with respect to one another. The connecting element is offset from the spindle axis by a predetermined distance. At least one vane extends between the vane support receiving elements on the two hubs. The vane captures air movement and translates it into rotational movement of the spindle.
