The best months for composite deck in Green Bay
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Green Bay (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in Green Bay are April through October: 7 of 12. Outside them, January, February, March, November and December have an average daytime high under 45°F.
In January, February, March, November and December the average high stays below 45°F. Sealants, adhesives and some materials, such as vinyl, are harder to install well in the cold, and short daylight cuts the working day.
Green Bay gets about 32 inches of precipitation in a normal year, including roughly 56 inches of snow. The wettest months are June, July and August (4.1 inches in June). Inside the workable window, April and October are the driest, at 3.0 and 2.7 inches. The station averages about 6 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

Who does the work: Green Bay trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 2 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Green Bay the blend is 1.03.
Carpenters (47-2031), 80% of the weighting: a median of $29.00 an hour, in line with the US median of $29.12. The middle half of them earn between $23.46 and $36.01 an hour. About 860 work in the metro. That is 49.3 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 20%) the local median is $26.39 an hour, which is 16% above the national $22.66. The middle half of them earn between $22.53 and $31.63 an hour. BLS counts 1,160 of them working in the area, 66.5 for every 10,000 jobs (US: 70.5), so the local bench is about average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $2,100 to the midpoint estimate; the 25th percentile takes off about $1,650. That is a swing of roughly 9.1% to 11.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Green Bay has 174,550 jobs in total (BLS, May 2025), ranking 133rd by size among the 300 metros on this site.
