A method for aligning a wind turbine with the wind direction is provided. The method includes measuring at least one first pressure at a first side of the wind turbine's nacelle, determining the pressure difference between the measured first pressure and a second pressure, and rotating the nacelle in dependence to the determined pressure difference. A wind turbine arrangement including a nacelle, a yaw alignment controller, and a yaw drive is also provided.
