Climate in Yakima: timing your home addition job
We use NOAA's 1991-2020 climate normals for Yakima Air Terminal (5 miles from the city center). These are 30-year monthly averages, not forecasts.
April through June and August through October are the stretches where digging, grading and setting material in the ground runs into the fewest weather problems in Yakima (6 of 12 months). January, February, March, November and December have an average overnight low at or below freezing (32°F); July has an average daytime high of 90°F or more.
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 147 days a year with a low at or below 32°F at this station.
Yakima gets about 8 inches of precipitation in a normal year, including roughly 20 inches of snow. The wettest months are January, November and December (1.4 inches in December). Inside the workable window, August and September are the driest, at 0.2 and 0.2 inches. The station averages about 40 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.

Yakima labor market for home addition
Wages are the part of this estimate that changes most from town to town. 6 trades carry the job here, and each is compared with its US median. The weighted result for Yakima is 1.10 times the national level.
For carpenters (47-2031, weighted 50%) the local median is $30.43 an hour, which is 4% above the national $29.12. The middle half of them earn between $27.61 and $44.37 an hour. BLS counts 480 of them working in the area, 49.5 for every 10,000 jobs (US: 43.1), so the local bench is about average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $42.23 an hour, which is 54% above the national $27.41. The middle half of them earn between $30.27 and $56.59 an hour. BLS counts 130 of them working in the area, 13.4 for every 10,000 jobs (US: 13.3), so the local bench is about average.
Electricians (47-2111), 10% of the weighting: a median of $37.81 an hour, 24% above the US median of $30.38. The middle half of them earn between $34.17 and $53.55 an hour. About 390 work in the metro. That is 40.2 per 10,000 jobs, compared with 48.7 nationally, so expect fewer local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $29.28 an hour, which is 5% below the national $30.67. The middle half of them earn between $24.00 and $40.04 an hour. BLS counts 240 of them working in the area, 24.7 for every 10,000 jobs (US: 30.0), so the local bench is thinner than average.
Drywall and ceiling tile installers (47-2081), 10% of the weighting: a median of $28.34 an hour, in line with the US median of $28.33. The middle half of them earn between $18.50 and $36.56 an hour. About 50 work in the metro. That is 5.2 per 10,000 jobs, compared with 5.3 nationally, so the supply of crews looks typical.
For roofers (47-2181, weighted 10%) the local median is $27.24 an hour, which is in line with the national $26.65. The middle half of them earn between $26.89 and $36.14 an hour. BLS counts 160 of them working in the area, 16.5 for every 10,000 jobs (US: 8.7), so the local bench is deeper than average.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($44.37 an hour) instead of the median, the labor line grows by about $9,150. At the 25th percentile ($27.61) it shrinks by about $1,850. The total moves by 14.7% or 3.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 97,010 jobs in the Yakima area. That makes it the 208th largest of the 300 metros we cover, with 0.06% of US employment.
