Mississippi Weather

Mississippi climate

Mississippi has a humid subtropical climate with long, hot summers and short, mild winters. The state receives heavy precipitation, averaging 55 to 65 inches per year, making it one of the wettest states in the Southeast. Gulf moisture dominates the state's weather for much of the year, contributing to high humidity and frequent thunderstorm activity.

The state is highly vulnerable to severe weather, including tornadoes, hurricanes, and flooding. Mississippi sits within Dixie Alley and experiences tornadoes year-round, with peak activity in spring. Hurricane Katrina in 2005 devastated the Mississippi Gulf Coast with a catastrophic 28-foot storm surge. The Mississippi River and its tributaries pose constant flooding threats during heavy rain events.

Summers in Mississippi are hot and oppressive, with temperatures regularly reaching the mid-90s and heat indices exceeding 110 degrees Fahrenheit. Air conditioning is considered essential for daily life from May through September. Winters are mild, with freezing temperatures occurring primarily in the northern part of the state, and snow is a rare event that generates significant excitement when it does occur.
