The skin
effect does not depend on:
Nature of
material
Size of wire
Supply frequency
Ambient temperature
Ambient temperature
The skin
effect is depending upon-
(1) Frequency
of supply
(2) Diameter
of conductor 
D2 (shape of conductor)
(3) Distance
between the conductors
(4)
Permeability of conductor material 
(Nature of material)
(5)
Conductivity of conductor.
Hence ambient temperature does not depend on skineffect.
