Climate in Dayton: timing your detached garage job
We use NOAA's 1991-2020 climate normals for Dayton Mcd (5 miles from the city center). These are 30-year monthly averages, not forecasts.
April through October is the stretch where pouring concrete runs into the fewest weather problems in Dayton (7 of 12 months). January, February, March, 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.
Dayton gets about 42 inches of precipitation in a normal year, including roughly 12 inches of snow. The wettest months are April, May and June (4.5 inches in April). Inside the workable window, September and October are the driest, at 3.0 and 3.0 inches. The station averages about 39 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.

Dayton labor market for detached garage
Wages are the part of this estimate that changes most from town to town. 5 trades carry the job here, and each is compared with its US median. The weighted result for Dayton is 1.01 times the national level.
For carpenters (47-2031, weighted 45%) the local median is $28.04 an hour, which is 4% below the national $29.12. The middle half of them earn between $23.03 and $31.60 an hour. BLS counts 950 of them working in the area, 25.5 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Construction laborers (47-2061), 20% of the weighting: a median of $25.48 an hour, 12% above the US median of $22.66. The middle half of them earn between $22.00 and $35.00 an hour. About 1,390 work in the metro. That is 37.3 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
For cement masons and concrete finishers (47-2051, weighted 15%) the local median is $30.09 an hour, which is 10% above the national $27.41. The middle half of them earn between $23.64 and $37.19 an hour. BLS counts 260 of them working in the area, 7.0 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Electricians (47-2111), 10% of the weighting: a median of $29.75 an hour, in line with the US median of $30.38. The middle half of them earn between $23.38 and $37.96 an hour. About 1,920 work in the metro. That is 51.5 per 10,000 jobs, compared with 48.7 nationally, so the supply of crews looks typical.
For roofers (47-2181, weighted 10%) the local median is $24.72 an hour, which is 7% below the national $26.65. The middle half of them earn between $22.20 and $29.78 an hour. BLS counts 320 of them working in the area, 8.6 for every 10,000 jobs (US: 8.7), so the local bench is about average.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($31.60 an hour) instead of the median, the labor line grows by about $1,200. At the 25th percentile ($23.03) it shrinks by about $1,650. The total moves by 2.8% or 3.9%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 372,660 jobs in the Dayton-Kettering-Beavercreek area. That makes it the 70th largest of the 300 metros we cover, with 0.24% of US employment.
