Springfield weather and the composite deck calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Springfield #2 (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 Springfield are March through November: 9 of 12. Outside them, January, February and December have an average daytime high under 45°F.
In January, February 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.
Springfield gets about 40 inches of precipitation in a normal year. The wettest months are May, June and July (5.1 inches in May). Inside the workable window, March and August are the driest, at 3.0 and 2.9 inches. The station averages about 23 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.

What local crews earn in Springfield
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 Springfield the blend is 1.28.
Carpenters (47-2031), 80% of the weighting: a median of $37.01 an hour, 27% above the US median of $29.12. The middle half of them earn between $26.51 and $39.67 an hour. About 290 work in the metro. That is 28.8 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $29.52 an hour, which is 30% above the national $22.66. The middle half of them earn between $21.56 and $35.79 an hour. BLS counts 510 of them working in the area, 50.6 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $790 to the midpoint estimate; the 25th percentile takes off about $3,100. That is a swing of roughly 15.1% to 3.8% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Springfield has 100,810 jobs in total (BLS, May 2025), ranking 203rd by size among the 300 metros on this site.
