Does Artificial Grass Get Hot Enough to Burn Bare Feet?

Yes, and Australian research backs it up

Ask anyone who has crossed a synthetic lawn barefoot on a hot afternoon and you already know the answer. Artificial turf gets hot enough in direct Australian sun to burn skin, and several Australian studies have put real numbers behind that experience.

A sheet of dark green plastic laid flat in full sun heats up faster and reaches a higher peak than the living grass, pavers or bare dirt around it, a bigger gap than most people expect until they feel it underfoot. The risk is real and well understood, and a handful of habits around colour, shade and water bring it back under control, much the way pavers and playground equipment already get managed through an Australian summer.

How hot artificial turf gets in Australian sun

Dr Sebastian Pfautsch, a Western Sydney University researcher, has spent years measuring turf temperatures across greater Sydney. His work, reported by the ABC, has recorded unshaded artificial turf running past 80°C even when air temperatures sit below 30°C, with readings climbing beyond 100°C on the hottest days. He describes plastic grass as the hottest surface he measures, hotter than playground rubber soft-fall. Natural grass nearby tends to track much closer to air temperature.

A New South Wales Government report on schools across western Sydney found similar numbers in the field, turf surfaces frequently reaching around 75°C against roughly 37°C for nearby natural grass. A peer-reviewed study tracking a Melbourne backyard over a full summer, published on ScienceDirect, measured artificial turf's daytime mean surface temperature at around 49.9°C, well above both irrigated (29.9°C) and unirrigated (31.7°C) natural grass nearby, exceeding the study's 48°C skin-burn threshold for close to four hours a day on average.

Full summer sun consistently turns synthetic turf into a genuinely hot surface, worth the same caution as a metal playground slide or a car seatbelt buckle on a 35 degree day.

Surface	Typical reading in full summer sun
Irrigated natural grass	Upper 20s to low 30s °C
Unirrigated natural grass	Low to mid 30s °C
Artificial turf, unshaded	70-100°C on a hot day

Why plastic grass runs hotter than living grass

Living grass cools itself by transpiring water through its blades, the same evaporative cooling that makes a well-watered lawn noticeably cooler than the driveway beside it on a hot day. Artificial turf has no water to evaporate, so nearly all the solar energy landing on it converts straight into surface heat instead.

Two more factors stack on top of that. Darker pigments absorb more solar energy than lighter ones, which is part of why deep lawn-green blends run hotter than paler, more olive-toned ones. The polyethylene yarn and the infill beneath it also have low thermal mass, so they heat up fast in direct sun and cool down fast once it's gone, unlike concrete or brick, which move more slowly in both directions.

A documented Australian case

Real incidents back up the lab measurements. CHOICE, Australia's consumer group, reported that in 2020 three toddlers sustained second-degree burns after walking barefoot over artificial turf at their childcare centre.

Children carry more risk than adults on the same surface. Their skin is thinner, they're closer to the ground, and they're the ones most likely to be running around barefoot in the first place. Burns from a hot surface don't need long contact once the surface is genuinely hot; a few seconds is enough, the same rule that already applies to a hot seatbelt buckle or a metal slide in summer.

The issue is serious enough that the New South Wales Government commissioned its Chief Scientist and Engineer to run an independent review into synthetic turf in public open spaces. Surface heat was one of the risks it examined, alongside broader gaps in what's known about synthetic turf's material makeup.

What cools it down

A few things move the number meaningfully, summarised below. Shade is the biggest lever of all: a shade sail, an established tree canopy or even a fence's afternoon shadow cuts surface temperature by far more than a yarn colour choice can on its own. Water works fast too, a short hose-down cools turf within seconds by pulling stored heat out through evaporation, though the surface starts climbing again as soon as it dries in full sun.

Some manufacturers market heat-reflective "cool yarn" technologies. Independent, published testing on how much difference these make under Australian conditions is still limited, so treat those marketing claims with a healthy amount of scepticism rather than assuming any product removes the problem outright.

Factor	Effect on surface temperature
Colour	Lighter, olive-toned blends run cooler than deep saturated green
Shade	The single biggest lever available
Water	Fast, short-lived cooling after a hose-down
Infill	Sand generally runs cooler than dark rubber crumb
"Cool yarn" claims	Not independently verified for Australian conditions

Does pile height matter

Only a little. Colour, infill and shade all move the number more than whether you've chosen a 20mm, 30mm or 40mm pile, a pattern our pile height guide covers in more detail. That means pile height can be chosen for look, feel and durability, while colour, infill and shade handle the heat side of the decision.

Turf Starter 20mm suits budget-focused, low-traffic spots, Turf Classic 30mm is the most popular all-rounder for family lawns, and Turf Pro 40mm gives the plushest feel for entertaining areas. Each product page has an instant calculator, so once you've settled on the spot and the shade plan around it, see current pricing on the product page and price your exact area in seconds.

Where the risk concentrates in your yard

Pool surrounds carry the highest stakes, because that's exactly where bare, wet feet spend the most time in direct sun. Our pool surrounds guide covers the trade-off honestly: turf beats hot pavers on softness and grip, but the coping and the main sunbathing spot still need a hose-down habit and, ideally, some shade over the areas people lie on.

Kids' play areas carry a similar risk with less ability to self-manage it, since a toddler won't hop off a hot patch the way an adult instinctively does. Our play areas guide covers what turf does and doesn't solve for cushioning and safety, and heat management is worth reading alongside it.

Balconies and rooftops deserve a mention too. The concrete slab underneath the turf holds and radiates its own heat on top of whatever the turf absorbs directly, often pushing the surface hotter than a ground-level yard sees on the same day.

A simple hot-day routine

1. Touch-test first. On any day forecast above the low 30s, a couple of seconds with your palm flat on the turf tells you what a bare foot is about to feel.
2. Hose it down before kids or pets go outside. Thirty seconds of water buys a genuinely cooler window, especially combined with a few minutes of shade beforehand.
3. Build shade in from the start. A shade sail is far cheaper to add now than to retrofit later, and it remains the single most effective fix available.
4. Keep a paver or timber path through high-traffic spots, like the pool edge or the trampoline run-up, so bare feet have a cooler option nearby on the hottest days.
5. Check the wider hot-weather checklist in our maintenance guide, including the reflected-glare issue from nearby windows that can heat isolated patches well beyond the rest of the lawn.

A hot backyard is worth planning for like any other sun-exposed surface: lighter colour where the spot gets full sun, shade over where people stand still, and the hose within reach.

Frequently asked questions

How hot can artificial turf get in an Australian backyard?

On a hot, sunny day, Western Sydney University research has recorded unshaded artificial turf running past 80°C even when the air temperature stays under 30°C, with readings climbing beyond 100°C on the hottest days. A New South Wales Government report on schools across western Sydney found similar numbers in the field, turf reaching around 75°C against roughly 37°C for nearby natural grass. The exact figure on any given day depends on colour, infill and how much direct sun the spot gets, but full summer sun consistently turns synthetic turf into one of the hottest surfaces in the yard.

At what temperature does artificial turf start to burn skin?

There's no single confirmed threshold for every product and every foot, because burn risk depends on both surface temperature and contact time, not temperature alone. Research on real turf in Australian summer conditions has found surface temperatures passing common skin-burn thresholds, around 48°C in one peer-reviewed study, for hours at a stretch, matching CHOICE's reporting of children with second-degree burns from barefoot contact. The safest habit is to test any dark, sun-exposed surface, turf included, with your hand before bare feet or paws go near it.

Does turf colour or pile height make a bigger difference to heat?

Colour makes a real difference: lighter, more olive-toned blends absorb less solar energy than deep saturated greens and run cooler in the same sun. Pile height has a much smaller effect by comparison, since shade, colour and infill choice all move the number more than whether the turf is 20mm, 30mm or 40mm. If a hot backyard is a real concern, put your planning effort into colour and shade rather than pile height.

Is it safe for kids and pets to play on artificial turf in an Australian summer?

It's safe with a bit of management, the same way a paved path or a metal slide needs management on a genuinely hot day. A quick hose-down before bare feet or paws go on it, combined with some shade over the areas used most, handles the bulk of the risk. Keeping a paver or timber path through the busiest spots, like a pool edge or a trampoline run-up, gives a cooler option nearby, since kids and dogs are both less likely than adults to move off a hot surface before real discomfort sets in.
