Abstract: We discuss how the surface gravity can be classically defined for dynamical black holes. In particular, we focus on defining the surface gravity for locally defined horizons and compare a number of definitions proposed in the literature. We illustrate the differences between the various proposals in the case of an arbitrary dynamical, spherically symmetric black hole spacetime. We also discuss how the trapping horizon formalism of Hayward can be related to other constructions.
