We install artificial turf. We also talk people out of it. Here is the heat problem nobody selling it wants to lead with, and the three situations where it is still the right call.
We install artificial turf. We have also talked a fair number of people out of it, which is an odd thing for a landscaper to admit in writing. The reason is that in this climate artificial grass solves one problem extremely well and creates another that nobody selling it leads with.
The heat problem, with an actual number
A study at BYU measured synthetic turf reaching 157°F on a day when the air temperature averaged 81°F. Natural grass on the same day, under the same conditions, peaked at 88.5°F. The synthetic surface was also measured hotter than asphalt.
Read those numbers again in the context of a Washington County July, when air temperatures run thirty degrees above that study's 81°F. Research elsewhere has recorded synthetic surfaces at up to 200°F with air temperatures around 98°F.
The physics is straightforward. Natural grass is mostly water and it transpires. It cools itself the way sweating cools you. Synthetic fibres are polyethylene or polypropylene. They absorb solar radiation and they hold it, and they have no mechanism for shedding it except radiating back into the air above them. Dark-colored infill makes it worse.
What that means in practice
- Bare feet are not viable on unshaded turf in a Southern Utah summer afternoon.
- Dogs will avoid it, and paw burns are a genuine risk rather than a theoretical one.
- A turf lawn against a south or west wall re-radiates heat back at the house, which your air conditioning then pays for.
- In Ivins, where red sandstone already re-radiates heat into landscapes, the effect compounds.
Where artificial turf is the right call
With all of that said, there are three situations where we recommend it without hesitation.
1. Shaded areas where nothing will grow
A side yard on the north, a courtyard between walls, under a mature tree. Places with enough shade that grass has never worked and enough traffic that gravel looks wrong. Shade removes the heat objection almost entirely, and these are usually spaces where living turf has failed repeatedly.
2. Small, high-traffic areas
A dog run, a putting green, a narrow strip by a gate. Areas too small and too worn for grass to establish, where the alternative is bare dirt. The heat matters less on a surface nobody lingers on.
3. Rental and second properties
This is the strongest case in our market. A Hurricane nightly rental with weekly guest turnover needs to look right continuously, and the owner is often not in town. Turf removes the failure mode where a missed irrigation cycle in July costs you a season of listing photos. We cover the rental-specific version of this in the short-term rental article.
Where we suggest something else
Large open front yards. This is the most common request and usually the worst application. Full sun, large area, high visibility, and the heat effect at its strongest. A desert conversion costs less, looks more appropriate to Southern Utah, and in four of our six cities it comes with a rebate attached.
Anywhere children play barefoot. Self-explanatory once you have seen the surface temperature figures.
Where the actual goal is lower water bills. Turf will do that, but so will a planted desert landscape, at lower installed cost and without the heat penalty. If water is the motivation rather than the look, compare the two properly before deciding.
The honest cost comparison
Artificial turf costs significantly more per square foot installed than either sod or a planted desert conversion. Its case is made over time. No watering, no mowing, no reseeding. So the question is how long you intend to own the property and how much the ongoing maintenance of the alternative actually costs you.
Two things that are frequently left out of that calculation:
- Artificial turf does not qualify for the turf removal rebate. The Water Conservancy District's program requires the converted area to reach at least 50% living plant cover at maturity using water-efficient vegetation. Synthetic grass is not living plant cover. If you remove lawn and install turf, you get no rebate; if you remove lawn and install a planted desert landscape, in St George, Washington, Santa Clara or Ivins you get $2 per square foot. That is a substantial swing that most turf quotes do not mention.
- It has a lifespan. Good turf lasts a long time but not forever, and UV exposure at this latitude and altitude is punishing. Budget for replacement rather than assuming permanence.
If you do install it, these three things matter
- Base preparation. Same as hardscape. Compacted aggregate base, properly graded for drainage. Turf over poorly prepared ground ripples and holds water, and both problems are permanent once the turf is down.
- Infill choice. Dark infill amplifies heat retention. Lighter and cooling infills exist and make a measurable difference; some systems with cooling infill or sub-surface micro-irrigation can bring surface temperatures much closer to natural grass for a period after watering.
- Shade. The single most effective heat mitigation is not a product, it is a tree or a structure. Turf under shade is a completely different surface from turf in full sun.
Our actual recommendation
Use artificial turf surgically. Small areas, shaded areas, high-traffic areas, rentals. Do not use it as a wholesale replacement for a large sunny lawn in this climate. And if the underlying goal is to stop fighting a lawn that dies every July, read why that happens first, because the fix is sometimes just a mower height and an irrigation repair.
