Hawaii seasons and sprinkler system
Season matters for sprinkler system. For each Hawaii metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Honolulu has the longest comfortable season of the metros we cover in Hawaii at 12 months; Kahului has the shortest at 10 (October through July). Rainfall runs from 16 inches a year in Kahului to 16 inches in Honolulu.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Honolulu | 67 | 88 | 16 | 12: all year |
| Kahului | 64 | 89 | 16 | 10: October through July |
Hawaii labor market for sprinkler system
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 3 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.53 for Hawaii.
For plumbers, pipefitters and steamfitters (47-2152, weighted 40%) the local median is $37.53 an hour, which is 22% above the national $30.67. The middle half of them earn between $29.60 and $47.09 an hour. BLS counts 2,500 of them working in the state, 39.8 for every 10,000 jobs (US: 30.0), so the local bench is deeper than average.
Construction laborers (47-2061), 40% of the weighting: a median of $37.07 an hour, 64% above the US median of $22.66. The middle half of them earn between $25.13 and $42.19 an hour. About 4,580 work in the state. That is 73.0 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
For operating engineers and other construction equipment operators (47-2073, weighted 20%) the local median is $55.70 an hour, which is 94% above the national $28.78. The middle half of them earn between $35.19 and $58.55 an hour. BLS counts 2,380 of them working in the state, 37.9 for every 10,000 jobs (US: 30.7), so the local bench is deeper than average.
A crew paid at the 75th percentile for plumbers, pipefitters and steamfitters ($47.09 an hour) would add about $450 to the statewide midpoint; one at the 25th percentile ($29.60) would take off about $380. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 627,530 jobs across Hawaii (May 2025), which is 0.4% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|

|---|---|---|---|
| Kahului, HI | $5,450 – $13,600 | $9,500 | +2% |
