Right now in Daly City, the air is about 56°F, but the model estimates the asphalt under your dog's paws is closer to 59°F — a gap of roughly 3°F, because heavy cloud cover is taking some of the edge off the direct sun. That reading puts Daly City 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 16 hours left today, the pavement in Daly City is projected to top out near 109°F around 1 PM, when the air will be about 68°F — a 40°F gap between the forecast your weather app shows and the surface your dog walks on. The surface is still gaining — up about 40°F over the next three hours — so a walk taken now is cooler than the same walk later this afternoon.
In an average August, Daly City sees highs around 65°F and overnight lows near 57°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.
Daly City loses its all-day safe window in 1 month of the year — June — and August is not one of them. The year peaks in October at an average high of 66°F against 56°F in December, a 11°F swing that decides how much of the day belongs to your dog.
Daly City sits about 5 miles from San Francisco, 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 Daly City 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.
