Why Kahului prices look the way they do
We price the labor side from BLS wage data for 4 trades: construction laborers at 40%, operating engineers and other construction equipment operators at 30%, brickmasons and blockmasons at 20%, plumbers, pipefitters and steamfitters at 10%. Weighted together, Kahului wages are 1.68 times the national level. Labor makes up about 62% of the midpoint estimate (52% at national prices).
Materials are scaled with BEA's regional price parity for goods. Kahului is at 111.6 against 100 for the US, so a materials line of $35,600 nationally becomes $39,700 here (midpoint, 450 sq ft). Permits follow the all-items index of 109.4: $110 to $330.
Data note: 20% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Kahului. The wage table below marks each row.

The best months for inground pool in Kahului
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Kahului Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For pouring concrete, the comfortable months in Kahului are October through July: 10 of 12. Outside them, August and September have an average daytime high of 90°F or more.
Heat matters for concrete as well. With average highs of 90°F or more in August and September, crews often start early, wet the base and plan for faster set times.
Kahului gets about 16 inches of precipitation in a normal year. The wettest months are January, March and December (2.8 inches in December). Inside the workable window, June and July are the driest, at 0.2 and 0.5 inches. The station averages about 39 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.

Who does the work: Kahului trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 4 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 Kahului the blend is 1.68.
For construction laborers (47-2061, weighted 40%) the local median is $38.35 an hour, which is 69% above the national $22.66. The middle half of them earn between $28.72 and $47.03 an hour. BLS counts 630 of them working in the area, 85.4 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), 30% of the weighting: a median of $60.09 an hour, 109% above the US median of $28.78. The middle half of them earn between $33.42 and $62.07 an hour. About 400 work in the metro. That is 54.2 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
Brickmasons and blockmasons (47-2021) carry 20% of the labor weighting. BLS does not publish this trade for the Kahului metro, so we used the Hawaii statewide median: $38.10 an hour against $29.87 for the US. The middle half of them earn between $22.81 and $43.72 an hour.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $37.31 an hour, 22% above the US median of $30.67. The middle half of them earn between $28.92 and $50.02 an hour. About 310 work in the metro. That is 42.0 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (construction laborers) from the median to the 75th percentile wage adds about $5,950 to the midpoint estimate; the 25th percentile takes off about $6,600. That is a swing of roughly 6.3% to 5.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Kahului-Wailuku has 73,750 jobs in total (BLS, May 2025), ranking 250th by size among the 300 metros on this site.
