Concrete Pouring Weather in Mississippi: Best Months by City
Concrete Pouring season in Mississippi, city by city: peak months, season boundaries, and annual workable-day counts from NOAA 1991–2020 normals. Gulfport leads with 219 workable days a year; Jackson runs the shortest at 159.
Across Mississippi's 3 listed cities, annual workable days for concrete pouring run from 159 (Jackson) up to 219 (Gulfport). Every number comes from NOAA 1991–2020 normals scored against the same label ruleset; every city name links to its live 10-day check.
If one month anchors the Mississippi calendar it's October, the statewide leader in workable days. Use this page to pick the month, then the city page's 10-day strip to pick the days — and the national concrete pouring guide for the physics behind each rule.
Cities in Mississippi
| City | Peak months | Season | Workable days/yr |
|---|---|---|---|
| Jackson | Oct, May, Nov | February–June | 159 |
| Gulfport | Oct, May, Apr | September–June | 219 |
| Hattiesburg | Oct, Nov, May | February–June | 166 |
The rules behind these numbers
| Check | Threshold | Why it matters |
|---|---|---|
| Air temperature | 40–90°F — ideal 50–85°F | DIY pours work from 40–90°F; 50–85°F is the sweet spot. |
| Overnight low | ≥40°F during the first 48 h | A low under 40°F inside the first 48 hours puts you in cold-weather concreting — not a DIY window. |
| Dry before | no soaking (≥1.0") in the prior 24 h | Rain before the pour only matters if the ground is soaked or standing in water. |
| Dry after | <0.1" rain for 6 h after (12 h light rain after finishing still risks surface marks) | A downpour in the first 6 hours can wash the surface; after final set, rain actually helps curing. |
| Wind | ≤20 mph (rapid surface drying up to 28 mph) | Hot wind pulls bleed water out faster than the slab can handle. |
Always follow your product label — formulas vary. The table above is the typical range across major manufacturers, not a promise about your can.
