Cassiopeia is located in the northern sky and from latitudes above 34°N it is visible year-round. In the (sub)tropics it can be seen at its clearest from September to early November, and at low southern, tropical, latitudes of less than 25°S it can be seen, seasonally, low in the North.

The constellation Cetus, the sea monster, can be seen in the northern hemisphere in the late fall and early winter. It is visible at latitudes between 70 degrees and -90 degrees.
