Climate in Port St. Lucie: timing your home addition job
We use NOAA's 1991-2020 climate normals for Ft Pierce St Lucie Co Intl Ap (15 miles from the city center). These are 30-year monthly averages, not forecasts.
September through June is the stretch where digging, grading and setting material in the ground runs into the fewest weather problems in Port St. Lucie (10 of 12 months). July and August have an average daytime high of 90°F or more.
Port St. Lucie gets about 51 inches of precipitation in a normal year. The wettest months are June, August and September (6.9 inches in August). Inside the workable window, February and December are the driest, at 2.2 and 2.3 inches. The station averages about 67 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.

BLS counts 1,060 of them working in the area, 62.1 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $23.21 an hour, which is 15% below the national $27.41.

Electricians (47-2111), 10% of the weighting: a median of $28.14 an hour, 7% below the US median of $30.38. The middle half of them earn between $22.97 and $29.43 an hour. About 1,100 work in the metro. That is 64.4 per 10,000 jobs, compared with 48.7 nationally, which suggests plenty of local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $24.52 an hour, which is 20% below the national $30.67.

At the 25th percentile ($20.65) it shrinks by about $1,800. The total moves by 6.2% or 3.6%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 170,820 jobs in the Port St. Lucie area. That makes it the 137th largest of the 300 metros we cover, with 0.11% of US employment.
