Across Maine's 2 listed cities, annual workable days for concrete pouring run from 105 (Augusta) up to 113 (Portland). 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 Maine calendar it's August, 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.

Top 2 Maine calendars for concrete pouring
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.
