San Luis Obispo weather and the sprinkler system calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, San Luis Obispo 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 San Luis Obispo: 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.
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.
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 San Luis Obispo
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 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 San Luis Obispo the blend is 1.17.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $30.33 an hour, in line with the US median of $30.67. The middle half of them earn between $28.38 and $39.95 an hour. About 320 work in the metro. That is 26.2 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 40%) the local median is $28.92 an hour, which is 28% above the national $22.66. The middle half of them earn between $23.31 and $36.80 an hour. BLS counts 1,030 of them working in the area, 84.4 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $38.14 an hour, 33% above the US median of $28.78. The middle half of them earn between $30.15 and $56.13 an hour. About 530 work in the metro. That is 43.4 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $460 to the midpoint estimate; the 25th percentile takes off about $95. That is a swing of roughly 1.2% to 5.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
San Luis Obispo-Paso Robles has 122,020 jobs in total (BLS, May 2025), ranking 178th by size among the 300 metros on this site.
