At an air temperature of 75°F (24°C), it is generally safe to walk a dog, but with one caveat: in direct midday sun, dark asphalt can run much hotter than the air. Mornings, evenings, grass and shade are all comfortable.
Your dog walks on the ground, not the air - and the gap is large. On a sunny day, dark asphalt at 75°F air can reach roughly 44°C (111°F)–54°C (129°F) in direct sun, while shaded surfaces stay closer to 29°C (84°F). Light concrete sits between the two, and grass stays near the air temperature. This is why timing and surface matter more than the headline number.
Flat-faced breeds, thick or dark-coated dogs, puppies, seniors, and overweight or unwell dogs feel heat sooner and harder. If your dog is in one of these groups, be more cautious than the general advice above - see which dogs are most at risk in heat and the signs of heatstroke.
Temperature guides are a starting point, not the final word. Press the back of your hand on the pavement for 7 seconds: if you can’t hold it comfortably, it’s too hot for paws - choose grass, shade, or wait. See the full dog walking temperature chart.
At 75°F (24°C), it is generally safe to walk a dog, but with one caveat: in direct midday sun, dark asphalt can run much hotter than the air. Mornings, evenings, grass and shade are all comfortable.
On a sunny day, dark asphalt can sit roughly 44°C (111°F)–54°C (129°F) - well above the air. In shade it’s closer to 29°C (84°F). Always confirm with the 7-second hand test.
Walk in the early morning or evening, stick to grass and shade, keep it short, bring water, and do the hand test before stepping onto any pavement.
