Climate in Austin: timing your detached garage job
We use NOAA's 1991-2020 climate normals for Austin-Camp Mabry (5 miles from the city center). These are 30-year monthly averages, not forecasts.
October through May is the stretch where pouring concrete runs into the fewest weather problems in Austin (8 of 12 months). June, July, August and September have an average daytime high of 90°F or more.
Heat matters for concrete as well. With average highs of 90°F or more in June, July, August and September, crews often start early, wet the base and plan for faster set times.
Austin gets about 36 inches of precipitation in a normal year. The wettest months are May, June and October (5.0 inches in May). Inside the workable window, February and April are the driest, at 1.9 and 2.4 inches. The station averages about 123 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.

Austin 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 Austin is 0.87 times the national level.
For carpenters (47-2031, weighted 45%) the local median is $24.16 an hour, which is 17% below the national $29.12. The middle half of them earn between $23.05 and $28.01 an hour. BLS counts 2,540 of them working in the area, 19.6 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 $21.16 an hour, 7% below the US median of $22.66. The middle half of them earn between $18.34 and $23.12 an hour. About 11,140 work in the metro. That is 86.1 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
For cement masons and concrete finishers (47-2051, weighted 15%) the local median is $23.76 an hour, which is 13% below the national $27.41. The middle half of them earn between $21.66 and $27.82 an hour. BLS counts 2,650 of them working in the area, 20.5 for every 10,000 jobs (US: 13.3), so the local bench is deeper than average.
Electricians (47-2111), 10% of the weighting: a median of $29.03 an hour, 4% below the US median of $30.38. The middle half of them earn between $22.97 and $35.25 an hour. About 7,340 work in the metro. That is 56.7 per 10,000 jobs, compared with 48.7 nationally, which suggests plenty of local crews to bid.
For roofers (47-2181, weighted 10%) the local median is $22.76 an hour, which is 15% below the national $26.65. The middle half of them earn between $19.14 and $27.31 an hour. BLS counts 480 of them working in the area, 3.7 for every 10,000 jobs (US: 8.7), so the local bench is thinner than average.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($28.01 an hour) instead of the median, the labor line grows by about $1,300. At the 25th percentile ($23.05) it shrinks by about $370. The total moves by 3.3% or 0.9%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 1,293,690 jobs in the Austin-Round Rock-San Marcos area. That makes it the 24th largest of the 300 metros we cover, with 0.83% of US employment.
