PURPOSE: An apparatus and a method for measuring wind direction and wind speed are provided to compensate a change of ultrasonic wave velocity and to reduce power consumption. CONSTITUTION: An apparatus for measuring wind direction and wind speed comprises: a transmitting sensor, a plurality of receiving sensors, and an outputting module. A method for measuring wind direction and wind speed comprises: a step of periodically transmitting ultrasonic waves by the transmitting sensor(S110); a step of receiving the ultrasonic waves from the transmitting sensor(S120); and a step of calculating the wind direction and wind speed(S150). [Reference numerals] (AA) Start; (BB) End; (S110) Transmitting ultrasonic wave signals; (S120) Receiving the ultrasonic wave signals; (S130) Calculating the compensated transferring time of ultrasonic waves; (S140) Calculating the compensated transferring speed of the ultrasonic waves; (S150) Calculating wind direction; (S160) Calculating wind speed
