A method for ice detection for a wind turbine is provided. The method includes providing an ice condition threshold parameter adapted for distinguishing a condition during which icing may occur and a condition during which icing may not occur, measuring a wind velocity with a first anemometer, wherein the first anemometer being of a first type, measuring a wind velocity with a second anemometer, wherein the second anemometer being of a second type, and wherein the second type is different from the first type, evaluating, for a condition during which icing may occur, a deviation of the wind velocity measured with the first anemometer and the wind velocity measured with the second anemometer, and determine whether the deviation exceeds a limit value based on a calibration conducted under a condition during which icing may not occur.
