Right now in Green Bay, the air is about 59°F, but the model estimates the asphalt under your dog's paws is closer to 59°F — the surface and air have nearly converged because the pavement is shedding the day's stored heat after dark. That reading puts Green Bay 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 21 hours left today, the pavement in Green Bay is projected to top out near 109°F around 2 PM, when the air will be about 77°F — a 32°F gap between the forecast your weather app shows and the surface your dog walks on. The surface is holding roughly flat over the next three hours, so there is no meaningfully cooler hour coming soon — choose shade and grass rather than waiting it out.
In an average October, Green Bay sees highs around 59°F and overnight lows near 43°F. That keeps most of the day walkable, though a rare clear, calm afternoon can still warm exposed pavement more than the mild air suggests. For this month the normals suggest pavement rarely reaches unsafe temperatures here, but the seven-second hand test is still the final word on any given day.
Green Bay loses its all-day safe window in 3 months of the year — June through August — and October is not one of them. The year peaks in July at an average high of 82°F against 28°F in January, a 54°F swing that decides how much of the day belongs to your dog.
The nearest city we track is Milwaukee, roughly 102 miles from Green Bay — 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 Green Bay 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 Green Bay 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.
