Climate in Manchester: timing your concrete slab job
We use NOAA's 1991-2020 climate normals for Manchester Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
May through October is the stretch where pouring concrete runs into the fewest weather problems in Manchester (6 of 12 months). January, February, March, April, November and December have an average overnight low of 40°F or below.
The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.
Manchester gets about 40 inches of precipitation in a normal year. The wettest months are June, September and October (4.0 inches in June). Inside the workable window, July and August are the driest, at 3.3 and 3.4 inches. The station averages about 16 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.
| Month | Avg high °F | Avg low °F | Precip (in) | For this job |
|---|---|---|---|---|
| Jan | 34 | 17 | 2.4 | Cold |
| Feb | 37 | 19 | 2.7 | Cold |
| Mar | 46 | 27 | 3.5 | Cold |
| Apr | 59 | 38 | 3.3 | Cold |
| May | 70 | 48 | 3.4 | Workable |
| Jun | 79 | 58 | 4.0 | Workable |
| Jul | 84 | 64 | 3.3 | Workable |
| Aug | 82 | 62 | 3.4 | Workable |
| Sep | 75 | 54 | 3.7 | Workable |
| Oct | 62 | 42 | 3.9 | Workable |

Why two Manchester quotes can differ
Base and reinforcement
A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.
Truck and pump access
If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.
Small-job minimums
Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.
Planning more than one job in Manchester?
Because every project leans on different trades, Manchester's wage level does not move all prices equally. Against the US midpoint, asphalt driveway runs +2% and stamped concrete −1%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete driveway | 600 sq ft | $3,650 – $9,200 | level |
| Concrete patio | 300 sq ft | $1,250 – $4,000 | level |
| Detached garage | 576 sq ft | $28,800 – $57,800 | −1% |
| Stamped concrete | 400 sq ft | $3,200 – $7,900 | −1% |
| Asphalt driveway | 600 sq ft | $3,100 – $7,550 | +2% |
| Gravel driveway | 1,000 sq ft | $2,500 – $10,100 | −1% |
Manchester labor market for concrete slab
Wages are the part of this estimate that changes most from town to town. 4 trades carry the job here, and each is compared with its US median. The weighted result for Manchester is 1.00 times the national level.
For cement masons and concrete finishers (47-2051, weighted 50%) the local median is $27.38 an hour, which is in line with the national $27.41. The middle half of them earn between $22.98 and $29.00 an hour. BLS counts 80 of them working in the area, 4.0 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Construction laborers (47-2061), 30% of the weighting: a median of $22.84 an hour, in line with the US median of $22.66. The middle half of them earn between $19.68 and $26.49 an hour. About 1,070 work in the metro. That is 53.6 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
For operating engineers and other construction equipment operators (47-2073, weighted 10%) the local median is $29.02 an hour, which is in line with the national $28.78. The middle half of them earn between $25.00 and $33.38 an hour. BLS counts 210 of them working in the area, 10.5 for every 10,000 jobs (US: 30.7), so the local bench is thinner than average.
For carpenters (47-2031, weighted 10%) the local median is $29.47 an hour, which is in line with the national $29.12. The middle half of them earn between $23.91 and $35.02 an hour. BLS counts 820 of them working in the area, 41.1 for every 10,000 jobs (US: 43.1), so the local bench is about average.
Quotes come from real crews, not medians. If the cement masons and concrete finishers on your job are paid at the 75th percentile ($29.00 an hour) instead of the median, the labor line grows by about $45. At the 25th percentile ($22.98) it shrinks by about $130. The total moves by 1.2% or 3.4%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 199,560 jobs in the Manchester-Nashua area. That makes it the 115th largest of the 300 metros we cover, with 0.13% of US employment.
