If you can't hold the back of your hand flat against the pavement for seven full seconds, it's too hot for your dog's paws. That single test beats any temperature number, because pavement doesn't match the air — asphalt sitting in direct sun can run dramatically hotter than the reported air temperature, so a pleasant 80°F afternoon can still produce a surface that burns pads in under a minute. Test the actual surface you're about to walk on, every time, and if it fails, walk on grass, go at a different hour, or skip the walk.

Weather apps report air temperature measured in shade, several feet off the ground. Your dog walks on a dark, dense surface that has been absorbing solar radiation all day. Asphalt is close to a worst case: dark enough to absorb most of the sunlight hitting it, dense enough to store that heat, and slow to release it. Concrete runs cooler than asphalt but still gets hot. Artificial turf and metal — manhole covers, truck beds, balcony grating — can be worse than either.
The practical consequence: the gap between "air temperature" and "surface temperature" is largest exactly when people are most likely to assume it's fine — a sunny, breezy, moderate day.
Press the back of your hand flat against the surface — not your fingertips, which are tougher, and not your palm. Hold it for seven seconds. If you want to pull away before then, the surface is too hot. Do it on the actual route: the shaded stretch by your building and the open parking lot two blocks later are not the same surface.
Timing matters more than the calendar. Pavement peaks in the late afternoon, not at noon, because it keeps gaining heat as long as the sun is on it and holds that heat for hours after. Early morning is reliably the coolest window; a surface that felt fine at 8 a.m. can fail the test at 6 p.m. on the same day.
Pads don't blister instantly, so the signs often show up after the walk. Watch for limping or refusing to keep walking, repeated licking or chewing at the feet, pads that look red or darker than usual, and visible flaps of loose pad tissue. A dog suddenly lifting paws, hopping between feet, or trying to stop in shade mid-walk is telling you the ground is too hot right now — pick them up or move to grass.
Boots vs paw wax honestly compared — what each actually protects against, why fit decides whether boots work at all, and why the free pavement test still beats both.
