Thermal actuation of a riblet is described herein. An apparatus includes a riblet structure (300) defining an aerodynamic surface (303) of a vehicle. The apparatus also includes a thermal expansion element (304) within or operatively coupled to the riblet structure (300), wherein the thermal expansion element (304) changes shape in response to a surrounding temperature, to displace a movable portion (402) of the riblet structure (300), relative to the aerodynamic surface (303), to alter an aerodynamic characteristic of the vehicle.
