For cubic type II superconductors the H c2 anisotropy is evaluated in the non‐local regime, i.e., for metals with moderate impurity content at arbitrary temperatures below T c . In particular it is shown that the contributions of H c2 anisotropy originating from anisotropic electron‐electron coupling and those resulting from Fermi surface anisotropies differ in their impurity and temperature dependences.
