The 10 Hottest-Pavement Cities for Dogs (and the Safe Hours to Walk)
Air temperature is a terrible way to judge whether it's safe to walk your dog — because the danger is on the ground, not in the air. In direct sun, asphalt runs 40–60°F hotter than the air (see our pavement temperature guide for the science). So we ranked 75 U.S. cities by their summer pavement risk to find where paws are most at risk — and when it's still safe to walk.
Of the 75 cities we cover, 30 hit "high" summer pavement risk. These 10 are the most extreme.
The 10 hottest-pavement cities for dogs
| Rank | City | Summer high (air) | Pavement can reach | |------|------|------------------|--------------------| | 1 | Phoenix, AZ | 106°F | 150°F+ | | 2 | Las Vegas, NV | 106°F | 150°F+ | | 3 | Tucson, AZ | 101°F | 145°F+ | | 4 | Dallas, TX | 97°F | 140°F+ | | 5 | Austin, TX | 97°F | 140°F+ | | 6 | El Paso, TX | 97°F | 140°F+ | | 7 | San Antonio, TX | 96°F | 140°F+ | | 8 | Fort Worth, TX | 96°F | 140°F+ | | 9 | Houston, TX | 95°F | 140°F+ | | 10 | Sacramento, CA | 95°F | 140°F+ |
Pavement estimates assume direct sun during peak hours. Paw-pad burns can occur at 120°F, and at 150°F burns happen in under a minute.
Two patterns jump out. The desert Southwest (Phoenix, Las Vegas, Tucson, El Paso) is brutal but dry — the heat is extreme and lingers. Texas dominates the list because it pairs high heat with humidity (Houston walks in at 70% summer humidity), which makes it harder for dogs to cool themselves even off the pavement.
The safe hours are earlier than you think
In every one of these cities, the safe walking window in summer is early morning and late evening — but the margins are tighter than most owners assume:
- Before 7 AM — almost always safe. Pavement has shed its heat overnight. This is your best window in any hot city.
- 10 AM – 6 PM — avoid pavement. Surface temps peak around 2–3 PM, but they're already dangerous by late morning.
- After sunset — not automatically safe. Dark asphalt that baked all day can stay above 120°F for 2–3 hours after sunset. In Phoenix or Vegas, 9 PM can still be too hot.
The catch: those windows shift every day with cloud cover, humidity, and how hot the previous days were. A cloudy 95°F day is far safer than a sunny one.
Don't guess — check before you walk
The 7-second test (press the back of your hand to the pavement; if you can't hold it for 7 seconds, neither can your dog) works once you're outside. But the easier move is to check before you leave:
- Free tool: Is it too hot to walk your dog right now? — enter your city and we'll estimate the pavement temperature from live weather.
- In the app: Walk Window scores every hour of the day for pavement safety, tuned to your dog's breed, and alerts you before it turns dangerous — so in Phoenix you'll know whether 6 AM or 6 PM is the safer call today.
Living somewhere on this list doesn't mean skipping walks all summer. It means walking at the right hour — and knowing, not guessing, when that is.
