In general, the weather in Zaragoza is enjoyable. During the winter months, the tempature stays between 5-10 degrees celsus.  It Never snows and hardly ever rains as the city is located in a valley. The only negative thing about the winter months is there is a lot of wind, so often it feels colder outside.

The summer months are HOT and i would not recommend traveling a lot in july or august as it is between 35-40 degrees celsus every day!

If you plan on traveling, the best times are in september and october and march, april, may and june.
