Urban Surface Heat Test: Concrete, Grass, Rocks & Turf
How hot do city surfaces really get in the Arizona sun? In this video, I use a thermal thermometer to measure and compare surface temperatures of concrete, asphalt, rocks, grass, turf, mulch, and shaded areas across Phoenix. You'll see surprising heat differences between surfaces in full sun, under mulch, and even at night.
Whether you're a gardener, landscape designer, urban planner, or just trying to stay cool in summer, this urban heat island test reveals where the real heat hazards hide.
🌡️ Surfaces Tested:
Concrete sidewalks
Asphalt streets
Rock landscapes
Grass lawns (real & artificial turf)
Mulch (top & underneath)
Shaded areas
Nighttime cooling comparison
📍 Filmed in Phoenix, AZ (Zone 9B)
