Paw Safety Check
Is 20°C Too Hot to Walk Your Dog?
The short answer
At an air temperature of 20°C (68°F), 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.
What 20°C means for the pavement
Your dog walks on the ground, not the air - and the gap is large. On a sunny day, dark asphalt at 20°C air can reach roughly 40°C (104°F)–50°C (122°F) in direct sun, while shaded surfaces stay closer to 25°C (77°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.
What to do at 20°C
- Fine for normal walks in the morning, evening or shade
- On sunny afternoons, prefer grass and check dark pavement first
- Watch flat-faced and thick-coated dogs more closely
Which dogs are most at risk
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.
Always confirm with the hand test
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.
