Climate in Spartanburg: timing your composite deck job
We use NOAA's 1991-2020 climate normals for Spartanburg 3 Sse (5 miles from the city center). These are 30-year monthly averages, not forecasts.
August through June is the stretch where exterior installation runs into the fewest weather problems in Spartanburg (11 of 12 months). July has an average daytime high of 90°F or more.
Spartanburg gets about 50 inches of precipitation in a normal year. The wettest months are March, June and December (4.8 inches in March). Inside the workable window, September and November are the driest, at 3.6 and 3.7 inches. The station averages about 57 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.

Spartanburg labor market for composite deck
Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Spartanburg is 0.86 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $24.88 an hour, which is 15% below the national $29.12. The middle half of them earn between $22.32 and $29.04 an hour. BLS counts 300 of them working in the area, 18.2 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 $20.29 an hour, 10% below the US median of $22.66. The middle half of them earn between $17.77 and $23.33 an hour. About 1,310 work in the metro. That is 79.3 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($29.04 an hour) instead of the median, the labor line grows by about $1,250. At the 25th percentile ($22.32) it shrinks by about $760. The total moves by 7.6% or 4.6%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 165,150 jobs in the Spartanburg area. That makes it the 143rd largest of the 300 metros we cover, with 0.11% of US employment.
