Hartwell is located in the humid subtropical climate zone of the Southeastern United States. Hartwell is located in the Piedmont Plateau region along the eastern side of the Appalachian Mountainsat an elevation just above 800 feet. Due to some of the highest of elevations in the Appalachians being between Hartwell and Canada, this allows for slightly warmer conditions than areas further south such as Atlanta. One exception to this rule is called the "wedge" or Cold air damming. This is due to a large high pressure system in eastern Canada driving colder drier air down against the eastern side of the Appalachian Mountain range. When this phenomenon is joined by gulf moisture, it frequently causes ice storm or freezing rain in the region. This same geographical feature can also cause frequent drought. Hartwell averages 51.96 inches of precipitation annually. The average snowfall is 2 inches, although more can fall, it is just as likely to have no measurable snowfall in any given year. The Storm of the Century (1993) brought 6 inches of snow to the area.
