Climate in College Station: timing your home addition job
We use NOAA's 1991-2020 climate normals for College Stn (5 miles from the city center). These are 30-year monthly averages, not forecasts.
October through May is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in College Station (8 of 12 months). June, July, August and September have an average daytime high of 90°F or more.
College Station gets about 42 inches of precipitation in a normal year. The wettest months are May, June and October (4.9 inches in October). Inside the workable window, February and April are the driest, at 2.9 and 2.9 inches. The station averages about 117 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.

College Station labor market for home addition
Wages are the part of this estimate that changes most from town to town. 6 trades carry the job here, and each is compared with its US median. The weighted result for College Station is 0.78 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $22.58 an hour, which is 22% below the national $29.12. The middle half of them earn between $20.77 and $26.89 an hour. BLS counts 170 of them working in the area, 12.7 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $20.81 an hour, which is 24% below the national $27.41. The middle half of them earn between $18.10 and $23.54 an hour. BLS counts 260 of them working in the area, 19.4 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 $23.28 an hour, 23% below the US median of $30.38. The middle half of them earn between $20.35 and $28.76 an hour. About 500 work in the metro. That is 37.3 per 10,000 jobs, compared with 48.7 nationally, so expect fewer local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $23.93 an hour, which is 22% below the national $30.67. The middle half of them earn between $21.00 and $31.06 an hour. BLS counts 400 of them working in the area, 29.8 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the College Station metro, so we used the Texas statewide median: $22.88 an hour against $28.33 for the US. The middle half of them earn between $19.28 and $28.09 an hour.
Roofers (47-2181) carry 10% of the labor weighting. BLS does not publish this trade for the College Station metro, so we used the Texas statewide median: $22.13 an hour against $26.65 for the US. The middle half of them earn between $18.00 and $25.78 an hour.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($26.89 an hour) instead of the median, the labor line grows by about $2,850. At the 25th percentile ($20.77) it shrinks by about $1,200. The total moves by 5.9% or 2.5%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 134,040 jobs in the College Station-Bryan area. That makes it the 164th largest of the 300 metros we cover, with 0.09% of US employment.
