A wind detecting and alerting apparatus includes a wind-sensing member, a support member, and an annular member, all of which are electrically-conductive. The apparatus also includes a support platform, and an electrical alarm circuit. The wind-sensing member has an elongated arm, a wind vane mounted on the arm and capable of sensing wind direction, and a wind deflector mounted on the arm and capable of sensing wind velocity. The support member mounts the elongated arm of the wind-sensing member to undergo rotational movement in response to the sensing of wind direction by the wind vane and pivotal movement in response to the sensing of wind velocity by the wind deflector. The support platform mounts the support member in an upright orientation and mounts the annular member concentrically about and spaced outwardly from the upright support member and below the rotational path of the wind-sensing member. The electrical alarm circuit is electrically connected between the upright support member and the annular member and is normally in an open switch condition. The circuit is capable of changing to a closed switch condition upon pivotal movement of the wind-sensing member through a sufficient displacement to make electrical contact with the annular member in response to sensing of wind velocity above a preset magnitude.
