Spokane 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, Spokane Felts Fld (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 Spokane are April through October: 7 of 12. Outside them, January, February, March, November and December have an average overnight low at or below freezing (32°F).
In January, February, March, November and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 123 days a year with a low at or below 32°F at this station.
Spokane gets about 17 inches of precipitation in a normal year. The wettest months are January, November and December (2.2 inches in December). Inside the workable window, July and August are the driest, at 0.7 and 0.5 inches. The station averages about 29 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 Spokane
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 Spokane the blend is 1.14.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $35.00 an hour, 14% above the US median of $30.67. The middle half of them earn between $27.12 and $46.27 an hour. About 810 work in the metro. That is 31.7 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 $24.53 an hour, which is 8% above the national $22.66. The middle half of them earn between $21.24 and $31.37 an hour. BLS counts 1,700 of them working in the area, 66.5 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $35.75 an hour, 24% above the US median of $28.78. The middle half of them earn between $29.35 and $42.14 an hour. About 700 work in the metro. That is 27.4 per 10,000 jobs, compared with 30.7 nationally, so the supply of crews looks typical.
A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $540 to the midpoint estimate; the 25th percentile takes off about $370. That is a swing of roughly 4.9% to 7.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Spokane-Spokane Valley has 255,820 jobs in total (BLS, May 2025), ranking 101st by size among the 300 metros on this site.
