We study the relation between the mean effective surface temperature <T>_s and the internal temperature T_b for magnetic neutron stars, assuming that the magnetic field near the surface has a small-scale structure. The heavy-element (iron) and light-element (accreted) heat-blanketing envelopes are considered, and the results are compared with the case of a dipole magnetic field. We argue that the difference in the T_b(<T>_s)-relation for different magnetic configurations is always much smaller than the possible difference caused by variations of the chemical composition in the envelope.
