According to the United States Census Bureau, the city has a total area of 62 square miles (160 km2), of which 60 square miles (160 km2) is land and 2.7 square miles (7.0 km2) of it (4.3%) is water. The city is located in the Piedmont region of Virginia, at the highest navigable point of the James River. The Piedmont region is characterized by relatively low, rolling hills, and lies between the low, sea level Tidewater region and the Blue Ridge Mountains. Significant bodies of water in the region include the James River, the Appomattox River, and the Chickahominy River. In winter, the Piedmont is colder than the coast, with temperatures usually averaging in the upper 40s–lower 50s °F (8–12 °C) during the day and often dropping below the freezing point at night. The region averages around 3–5 in (8–13 cm) of snowfall annually in the Charlotte area, and slightly more north toward the Virginia border. The Piedmont is especially notorious for sleet and freezing rain. Freezing rain can be heavy enough to snarl traffic and break down trees and power lines. Annual precipitation and humidity are lower in the Piedmont than in the mountains or the coast, but even at its lowest, the average is 40 in (1,020 mm) per year.
