Right now in Pittsburgh, the air is about 68°F, but the model estimates the asphalt under your dog's paws is closer to 68°F — the surface and air have nearly converged because the pavement is shedding the day's stored heat after dark. That reading puts Pittsburgh in the clear for an ordinary walk. Air temperature alone would have told you none of this — the pavement, not the forecast, is what your dog actually stands on.
Only an hour of today are left in Pittsburgh, and the pavement is not expected to climb past about 68°F in that time. The surface is already coming down, about 3°F over the next three hours, so waiting a little works in your favour here.
In an average August, Pittsburgh sees highs around 82°F and overnight lows near 64°F. Even at those moderate highs, a dark surface in direct sun can run 40–60°F hotter than the air, which is enough to tip midday walks into the caution range. As a seasonal rule of thumb, the safest windows are before about 11:00 AM and after about 4:00 PM.
Pittsburgh loses its all-day safe window in 3 months of the year — June through August — and August is one of them. The year peaks in July at an average high of 85°F against 39°F in January, a 46°F swing that decides how much of the day belongs to your dog.
The nearest city we track is Akron, roughly 91 miles from Pittsburgh — far enough that its reading is no substitute for this one. Sun angle, humidity and cloud cover can all differ across that distance, which is why this page models Pittsburgh on its own coordinates.
Whatever the number says, confirm it with your hand: press the back of it flat on the pavement for seven seconds. If you can't hold it there, neither can your dog. Conditions in Pittsburgh are on the gentler side right now, but keep the same habits: water before and after, grass over asphalt, and a close eye on flat-faced breeds, seniors, and puppies, who overheat and burn sooner than a healthy adult dog.
