Right now in Tacoma, the air is about 69°F, but the model estimates the asphalt under your dog's paws is closer to 79°F — a gap of roughly 10°F, because a mix of sun and cloud is still loading heat into the asphalt. That reading puts Tacoma 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.
Across the 5 hours left today, the pavement in Tacoma is projected to top out near 79°F around 7 PM, when the air will be about 69°F — a 10°F gap between the forecast your weather app shows and the surface your dog walks on. The surface is already coming down, about 14°F over the next three hours, so waiting a little works in your favour here.
In an average August, Tacoma sees highs around 79°F and overnight lows near 58°F. Those are forgiving numbers, but don't let them lull you — a sunny, still afternoon can still heat dark asphalt far above the air, especially for low-riding or short-coated dogs. As a seasonal rule of thumb, the safest windows are before about 12:00 PM and after about 3:00 PM.
Tacoma loses its all-day safe window in 2 months of the year — July through August — and August is one of them. The year peaks in July at an average high of 79°F against 46°F in February, a 33°F swing that decides how much of the day belongs to your dog.
Tacoma sits about 13 miles from Kent, close enough that the two usually run within a degree or two of each other — if your walk crosses between them, either page answers the question. Street-level conditions still differ more than city-level ones do: a shaded side street and an open parking lot half a block apart can be twenty degrees apart underfoot.
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 Tacoma 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.
