Aurora is located in northeastern Illinois, straddling both the east and west sides of the Fox River. The Fox River Valley runs fairly north-south around the river. The area is part of the Great Lakes Plains, which is mainly flat except for some small hills in the west near the start of the Till Plains, the flat fertile area covering most of the state. Aurora is situated far enough away from Lake Michigan to not receive any lake effect snow, but still averages about 38 inches of snow a year, with January being the snowiest month. Temperatures in the summer months average in the low 80s, with about 4 inches of rainfall per month.
