Right now in Savannah, the air is about 80°F, but the model estimates the asphalt under your dog's paws is closer to 102°F — a gap of roughly 22°F, because a mix of sun and cloud is still loading heat into the asphalt. That reading puts Savannah in the clear for an ordinary walk. Humidity is nudging the human "feels-like" to about 86°F, which matters for your dog too: muggy air makes it harder for a panting dog to shed heat, so treat a borderline reading as the hotter of the two.
Across the 14 hours left today, the pavement in Savannah is projected to top out near 137°F around 1 PM, when the air will be about 91°F — a 46°F gap between the forecast your weather app shows and the surface your dog walks on. Today breaks into 2 separate safe stretches rather than one continuous window, so missing the first does not cost you the day.
In an average August, Savannah sees highs around 88°F and overnight lows near 74°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 10:00 AM and after about 5:00 PM.
Savannah loses its all-day safe window in 6 months of the year — April through September — and August is one of them. The year peaks in July at an average high of 90°F against 62°F in January, a 28°F swing that decides how much of the day belongs to your dog.
The nearest city we track is Charleston, roughly 83 miles from Savannah — 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 Savannah 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 Savannah 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.
