Concrete Pouring Weather in Tennessee: Best Months by City

Concrete Pouring season in Tennessee, city by city: peak months, season boundaries, and annual workable-day counts from NOAA 1991–2020 normals. Chattanooga leads with 144 workable days a year; Franklin runs the shortest at 114.

Tennessee is not one climate: Chattanooga banks 144 workable concrete pouring days a year while Franklin gets 114 — a spread the table below itemizes month by month. Season boundaries mark the first and last month averaging 8+ workable days against the label rules (40–90°F, nights 40°F+).

If one month anchors the Tennessee calendar it's September, 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.

The rules behind these numbers

Typical label thresholds for concrete pouring — the single ruleset used by every check on this page.
CheckThresholdWhy 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.
