Regional context

By the nearest station's NOAA NCEI 1991-2020 normals, Jackson sees 46°F Januarys and 83°F Julys, a 37°F range, plus around 45.8 inches of precipitation across 177 days.

Jackson's moisture rides winter storm tracks: December brings 5.4 inches over 15.3 wet days, while October sees only 2.2 inches across 8.5 days in the dry warm season. That groups Jackson with places like Richland, MS, Pearl, MS and Flowood, MS on the same cool-season storm track.

Freezes are uncommon in Jackson, where the coldest month averages 46°F; cool-season crops grow fall through spring. Summer heat in July (about 83°F) is the binding constraint, not cold. Jackson's coastal lots stay 4-7°F milder overnight than Jackson's inland parcels.

Similar climates: Richland, MS, Pearl, MS, Flowood, MS, Clinton, MS, Ridgeland, MS.

Late May brings the peak migration of indigo buntings through central Mississippi, their electric blue males singing from power lines and forest edges.
