Mississippi Climate

Mississippi has a warm humid subtropical climate with long summers and short, mild winters. Temperatures average about 82°F (about 28°C) in July and about 48 °F (about 9 °C) in January. The temperature varies little across the state in summer, but in winter the region near Mississippi Sound is significantly warmer than most of the rest of the state. The recorded temperature in Mississippi has ranged from -19 °F (-28.3 °C), in 1966, at Corinth in the northeast, to 115 °F (46.1 °C), in 1930, at Holly Springs in the north. Yearly precipitation generally increases from north to south. Thus, Clarksdale, in the northwest, gets about 50 inches (about 1,270 mm) of precipitation annually and Biloxi, in the south, about 61 inches (about 1,550 mm). Small amounts of snow fall in northern and central Mississippi, although snow is not unheard of around the southern part of the state.

In the late summer and the fall, the state (especially the southern part) is often affected by hurricanes moving north from the Gulf of Mexico, and occasionally impacted by major hurricanes, which can be quite devastating in coastal communities. Thunderstorms are common in Mississippi, especially in the southern part of the state. On average, Mississippi has around 27 tornadoes annually with the northern part of the state more vulnerable earlier in the year and the southern part becoming more vulnerable a little later.
