Consider the initial value problem for the three‐dimensional Navier–Stokes equations with rotation in the half‐space ℝ<sup>3</sup><sub>+</sub> subject to Dirichlet boundary conditions as well as the Ekman spiral, which is a stationary solution to the above equations. It is proved that the Ekman spiral is nonlinearly stable with respect to L<sup>2</sup>‐perturbations provided that the corresponding Reynolds number is small enough. Moreover, the decay rate can be computed in terms of the decay of the corresponding linear problem.
