When to schedule wood deck in San Luis Obispo
We use NOAA's 1991-2020 climate normals for San Luis Obispo Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
Weather is not a serious constraint for exterior installation in San Luis Obispo: no month in the averages is cold enough (an average daytime high under 45°F) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
San Luis Obispo gets about 18 inches of precipitation in a normal year. The wettest months are January, February and December (3.9 inches in January). The station averages about 15 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.

Local wages behind the labor line
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 San Luis Obispo is 1.28 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $37.12 an hour, which is 27% above the national $29.12. The middle half of them earn between $28.97 and $44.20 an hour. BLS counts 820 of them working in the area, 67.2 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
Construction laborers (47-2061), 20% of the weighting: a median of $28.92 an hour, 28% above the US median of $22.66. The middle half of them earn between $23.31 and $36.80 an hour. About 1,030 work in the metro. That is 84.4 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($44.20 an hour) instead of the median, the labor line grows by about $960. At the 25th percentile ($28.97) it shrinks by about $1,100. The total moves by 7.4% or 8.5%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 122,020 jobs in the San Luis Obispo-Paso Robles area. That makes it the 178th largest of the 300 metros we cover, with 0.08% of US employment.
