A creature protected by endure elements suffers no harm from being in a hot or cold environment. It can exist comfortably in conditions between -50 and 140 degrees Fahrenheit without having to make Fortitude saves (as described in the Dungeon Master's Guide). The creature's equipment is likewise protected.
Endure elements doesn't provide any protection from fire or cold damage, nor does it protect against other environmental hazards such as smoke, lack of air, and so forth.
