The first Homo Sapiens that left Africa avoided the cold regions and only settled areas that had a climate similar to Africa. Humans went from Africa to Southeren Middle East, Southeren India, Sri Lanka, Thailand, Indonesia and then to Australia. Europe and Siberia were not settled until humans had the technology (advanced clothing) and social skills to live in a cold environment where the group hunting large animals was going to be the main source of food.
As for non human hominids, some of them were better adapted for colder climates (stocky builds, hairier bodies). Even then, Neanderthals probably first evolved in the Middle East and then colonized Europe after they developed a more complete tool kit. The far more primitive Homo Erectus might have evolved locally. If so, they customized themselves for colder areas (Peking Man verse Java Man and African based erectuses). Anthropologists vary as to how human erectus was and the opinions range from "barely" to "nearly".
