That depends on whether the surface pressure is high enough to raise
the boiling temperature of nitrogen higher than the surface
temperature... or whether the surface temperature is lower than the
boiling temperature of nitrogen at the surface atmospheric pressure.


Temperatures in the polar regions would perhaps be low enough to liquefy
nitrogen.

Titan's orbital period around Saturn is 16 Earth days, and its
rotational period is also 16 days, so even in equatorial regions things
must get even colder during the 8 days of night, perhaps low enough to
liquefy nitrogen.
