Paw Safety Check
Is 90°F Too Hot to Walk Your Dog?
The short answer
At an air temperature of 90°F (32°C), it is dangerous on hard surfaces in the sun. Pavement can burn paws quickly and the risk of heat illness is high. Most dogs should not be exercised on pavement at this temperature during the day.
What 90°F 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 90°F air can reach roughly 52°C (126°F)–62°C (144°F) in direct sun, while shaded surfaces stay closer to 37°C (99°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 90°F
- Walk only at the coolest parts of the day, and keep it short
- Stay on grass and shade - avoid pavement entirely in the sun
- Prioritise indoor games and training over walks
- Provide constant shade and water; know the heatstroke signs
- Never leave your dog in a parked car, even briefly
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.
Frequently asked questions
Is 90°F too hot to walk a dog?
At 90°F (32°C), it is dangerous on hard surfaces in the sun. Pavement can burn paws quickly and the risk of heat illness is high. Most dogs should not be exercised on pavement at this temperature during the day.
How hot is the pavement when it’s 90°F?
On a sunny day, dark asphalt can sit roughly 52°C (126°F)–62°C (144°F) - well above the air. In shade it’s closer to 37°C (99°F). Always confirm with the 7-second hand test.
What’s the safest way to walk a dog at 90°F?
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.
