Charlotte lies in the southeastern United States’ Piedmont region and features a humid subtropical climate (Köppen Cfa) with four distinct seasons. Classified as USDA hardiness zone 8a—transitioning to 7b in most suburban areas—Charlotte enjoys mild winters, warm summers, and a long growing season of approximately 220 days.

Winter temperatures are generally short and mild, with a normal January daily mean of 42.1 °F (5.6 °C). While temperatures occasionally drop below 20 °F (−6.7 °C), many winter days reach highs above 65 °F (18.3 °C). Charlotte averages 59 nights per year at or below freezing, with just 1.5 days failing to rise above freezing.

Summers are hot and humid, with a normal July daily mean of 80.1 °F (26.7 °C) and an average of 44 days per year exceeding 90 °F (32 °C). Charlotte has experienced record highs of 104 °F (40 °C) and record lows down to −5 °F (−21 °C). Precipitation is evenly distributed throughout the year, averaging 43.6 inches (1,110 mm) annually, with August slightly wetter than other months. Seasonal snowfall is light, averaging 3.5 inches, mainly in January and February, though occasional ice storms and sleet are common, with historic extremes ranging from 0 to 22.6 inches in a season.

Charlotte’s location exposes it to subtropical moisture from the Gulf of Mexico, producing frequent rain and thunderstorms, particularly in spring and early summer. The area also enjoys many clear, sunny days. However, the metropolitan region faces a significant weather radar gap, with the nearest NWS-owned radar located over 80 miles away in Greer, South Carolina. This creates challenges for detecting severe thunderstorms or tornadoes in the Charlotte area, as radar coverage is limited near the ground.

Overall, Charlotte’s climate provides a balance of seasonal variation, abundant rainfall, and mild winters, supporting its extensive green spaces and year-round outdoor activities.
