Astrology can't be defined as either a science or an art.It is the combination of both.
Astrology is a science as it is based on the positions of the nine planets in different houses of a person's kundali.
And we can say that astrology is an art as it is a skill acquired by the astrologer by the experience.This skill is required for making the charts, understanding them,making the horscopes and predicting the dashas of a person for the whole life.
