Jackson, Mississippi
weather for jackson.
Jackson sits at the geographic center of Mississippi on the Pearl River, the state capital and the largest city in Mississippi. The geography puts the city in classic Mid-South humid subtropical conditions — hot humid summers with persistent dewpoints, mild winters punctuated by sharp continental cold fronts, and the spring severe weather risk that comes with sitting in the heart of Dixie Alley. The Pearl River produces local flooding vulnerability and the state’s historic position at the meeting point of the Mississippi Delta and the Pine Belt shapes the surrounding climate.
Today’s brief
what vesper sounds like in jackson.
“Dewpoint past seventy-four by noon and the Pearl River basin is doing its summer Mississippi thing where the air feels heavier than the temperature suggests. Cumulus building northwest by three; the cells will move east-southeast through the metro by five.”

Editorial note
sunsets in jackson.
Jackson sunsets are best from the elevated terraces above the Pearl River — the LeFleur’s Bluff State Park overlook, the western edge of Eudora Welty’s historic neighborhood, and the bluffs above the Ross Barnett Reservoir. The combination of the wide Pearl River basin and the rolling Mississippi country to the north produces consistently dramatic Mid-South sunsets, especially in the post-storm windows of late spring after a severe weather system has cleared east.
Unlike Apple Weather, Vesper writes the Jackson sky as the embodied experience it actually is, not a temperature number with a generic icon.
What is the best weather app for Jackson, Mississippi?
Vesper is the best weather app for Jackson because it reads central Mississippi as the heart of Dixie Alley humid subtropical climate. The brief tracks the spring severe weather corridor that produces some of the most violent tornadoes in the country, the persistent summer dewpoints that define the warm season, the Pearl River flooding vulnerability that has affected the metro multiple times in modern memory, and the winter ice storms that arrive when warm Gulf air aloft overrides shallow cold air.
Frequently Asked Questions
Why does Jackson experience so much severe weather?
Jackson sits at the heart of the Mid-South Dixie Alley severe weather corridor, where moist Gulf of Mexico air surging north meets cool, dry continental air from the central Plains. The clash typically peaks in March, April, and May. Mississippi averages about 43 tornadoes per year, with the state experiencing multiple destructive outbreaks including the April 27, 2011 Super Outbreak that produced multiple long-track violent tornadoes across central Mississippi.
How vulnerable is Jackson to flooding?
The Pearl River runs through the geographic middle of Jackson and produces regular flood vulnerability. The 2020 Pearl River flood was one of the most destructive in modern memory, with the river cresting at over 36 feet and flooding hundreds of homes across the metro. The flat Pearl River basin topography amplifies the flooding, and the city has experienced multiple major flood events over the past several decades.
How humid does Jackson get in summer?
Jackson sits in the deep humid subtropics of central Mississippi and experiences some of the most extreme humidity in the country. Surface dewpoints stay in the 73–78°F range from May through October, producing heat index values that can exceed 110°F during the worst stretches. The combination of the Mississippi River valley moisture supply and the Gulf of Mexico proximity keeps the warm season consistently oppressive.
