Modesto 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, Modesto City Co Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Modesto are September through May: 9 of 12. Outside them, June, July and August have an average daytime high of 90°F or more.
Modesto gets about 12 inches of precipitation in a normal year. The wettest months are January, February and December (2.6 inches in January). Inside the workable window, September and October are the driest, at 0.1 and 0.6 inches. The station averages about 90 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 Modesto
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 Modesto the blend is 1.21.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $30.42 an hour, in line with the US median of $30.67. The middle half of them earn between $26.76 and $38.00 an hour. About 470 work in the metro. That is 24.1 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 40%) the local median is $29.15 an hour, which is 29% above the national $22.66. The middle half of them earn between $22.89 and $38.02 an hour. BLS counts 1,070 of them working in the area, 54.8 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $43.54 an hour, 51% above the US median of $28.78. The middle half of them earn between $32.57 and $62.15 an hour. About 430 work in the metro. That is 22.0 per 10,000 jobs, compared with 30.7 nationally, so expect fewer 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 $360 to the midpoint estimate; the 25th percentile takes off about $170. That is a swing of roughly 2.2% to 4.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Modesto has 195,230 jobs in total (BLS, May 2025), ranking 117th by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
