A method of monitoring strain on a wind turbine blade that has several structural components comprises locating at least three strain sensors (2a, 2b, 2c) on one of the structural components of the turbine blade, the positions of the strain sensors defining a plane transverse to the longitudinal direction of the turbine blade and resolving strain signals from the three strain sensors into strain measurements in two orthogonal directions.
