We study the relation between the mean effective surface
temperature 
and the internal temperature 
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 
-relation for
different magnetic configurations is always much smaller than the
possible difference caused by variations of the chemical composition
in the envelope.
