Summer. For most of the gray wolves' range in the United States, summer temperatures range from temperatures in the 70s to 80s. This is not the case for Alaska, and also not the case for New Mexico and Arizona's population of Mexican wolves.pring and fall temperatures range from mild to severe, 30 to 60 degrees Fahrenheit is common. During the spring, the gray wolf's prey is becoming more active, creating a better chance of a meal for the pack. Breeding occurs during spring, anywhere from January to April depending on how far north the wolves are.
