Is the pavement too hot for your dog’s paws?
Asphalt in the sun runs far hotter than the air — often 40–60 °F hotter. That’s why a pleasant 80 °F afternoon can still mean pavement hot enough to burn a paw pad. WetBulbTracker estimates the actual ground temperature where you are, from live sun, air and wind.

Burn risk is continuous, not a switch: a pad can burn after about a minute at 125 °F and within seconds near 140 °F. These are human-skin thresholds — dog pads are tougher, so treat them as a conservative floor.
Air temperature vs. asphalt temperature
Field readings in direct sun with no wind (Berens, JAMA, 1970). Illustrative observations, not a formula — shade, wind and a lighter surface all read much cooler, which is why we estimate from live conditions instead of a lookup table.
The hand test
Press the back of your hand to the pavement. If you can’t hold it there comfortably (about 5–7 seconds), it’s too hot for paws. It’s a rule of thumb, not a measurement — but it’s the check you always have with you.
Common questions
How hot is too hot for a dog's paws?
Pavement at or above about 125 °F (52 °C) can burn a paw pad after roughly a minute of contact, and burns happen within seconds near 140 °F (60 °C). Discomfort starts much lower — skin pain begins around 110 °F (43 °C) — so a surface can be too hot for a comfortable walk well before it is hot enough to injure.
How much hotter is asphalt than the air?
On a clear day in direct sun, asphalt commonly runs 40–60 °F hotter than the air. In a classic Phoenix case series, asphalt measured about 125 °F when the air was 77 °F, and about 143 °F when the air was 87 °F. Shade, wind, cloud cover and a lighter surface all lower it substantially.
What is the 7-second rule for dog paws?
Press the back of your hand flat against the pavement. If you cannot hold it there comfortably — guides commonly say about 5–7 seconds, and the American Kennel Club suggests around 10 — it is too hot for your dog. It is a sensory rule of thumb, not a measurement, but it is the best check you always have with you.
Is pavement safe once the sun goes down?
Not necessarily. Asphalt stores heat and cools more slowly than the air, so it can stay dangerously hot for hours after sunset — exactly when many people walk their dogs. Our estimate accounts for that stored heat, but you should still check the surface with your hand.
What can I do when the pavement is too hot?
Walk on grass or dirt, go early in the morning or late in the evening, stick to shaded routes, or use protective booties. Watch for limping, stopping, licking at the paws, or refusing to walk — all signs the ground is hurting your dog.
Check the pavement where you actually are — it takes one tap, and the reading updates with the sun, wind and cloud cover.
