An assembly for monitoring air flow at a surface of a rotor blade of a wind turbine is described. The assembly comprises (a) a surface module adapted to be arranged at a predetermined location of the rotor blade surface, the surface module comprising two air inlets facing opposite directions along an axis, (b) a sensor module comprising two pressure sensors, wherein one of the two pressure sensors is in fluidic communication with one of the two air inlets and the other one of the two pressure sensors is in fluidic communication with the other one of the two air inlets, wherein the sensor module is adapted to output two pressure signals indicative of the pressures sensed by the two pressure sensors, and (c) a processing unit adapted to determine at least one of a flow direction and a flow speed along the axis based on the two pressure signals. Furthermore, a wind turbine and a method are described.
