Concrete Pouring Weather in Arizona: Best Months by City

Concrete Pouring season in Arizona, city by city: peak months, season boundaries, and annual workable-day counts from NOAA 1991–2020 normals. Phoenix leads with 198 workable days a year; Flagstaff runs the shortest at 73.

Across Arizona's 17 listed cities, annual workable days for concrete pouring run from 73 (Flagstaff) up to 198 (Phoenix). Every number comes from NOAA 1991–2020 normals scored against the same label ruleset; every city name links to its live 10-day check.

Statewide, April is the strongest month — it tops or ties the table in most listed cities. The live strips on each city page decide the week; this table decides the month. Scoring rules: methodology; the national playbook: the concrete pouring guide.

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.
