Salinas weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Salinas Municipal Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
Weather is not a serious constraint for digging, grading and setting material in the ground in Salinas: no month in the averages is cold enough (an average overnight low at or below freezing (32°F)) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
Salinas gets about 13 inches of precipitation in a normal year. The wettest months are January, February and December (2.6 inches in January). 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.

What local crews earn in Salinas
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 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 Salinas the blend is 1.14.
Carpenters (47-2031), 50% of the weighting: a median of $32.47 an hour, 12% above the US median of $29.12. The middle half of them earn between $24.94 and $39.57 an hour. About 1,210 work in the metro. That is 64.9 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $32.71 an hour, 19% above the US median of $27.41. The middle half of them earn between $27.39 and $49.38 an hour. About 200 work in the metro. That is 10.7 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $37.88 an hour, which is 25% above the national $30.38. The middle half of them earn between $28.51 and $46.58 an hour. BLS counts 530 of them working in the area, 28.4 for every 10,000 jobs (US: 48.7), so the local bench is thinner than average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $30.98 an hour, in line with the US median of $30.67. The middle half of them earn between $28.21 and $39.44 an hour. About 320 work in the metro. That is 17.2 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $35.41 an hour, which is 25% above the national $28.33. The middle half of them earn between $28.79 and $37.74 an hour. BLS counts 160 of them working in the area, 8.6 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $29.58 an hour, 11% above the US median of $26.65. The middle half of them earn between $28.76 and $35.68 an hour. About 240 work in the metro. That is 12.9 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $4,650 to the midpoint estimate; the 25th percentile takes off about $4,950. That is a swing of roughly 7.7% to 7.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Salinas has 186,430 jobs in total (BLS, May 2025), ranking 123rd by size among the 300 metros on this site.
