Right now in Lafayette, the air is about 84°F, but the model estimates the asphalt under your dog's paws is closer to 93°F — a gap of roughly 9°F, because a mix of sun and cloud is still loading heat into the asphalt. That reading puts Lafayette 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 6 hours left today, the pavement in Lafayette is projected to top out near 93°F around 6 PM, when the air will be about 84°F — a 9°F gap between the forecast your weather app shows and the surface your dog walks on. The surface is already coming down, about 18°F over the next three hours, so waiting a little works in your favour here.
In an average October, Lafayette sees highs around 80°F and overnight lows near 63°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. 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.
Lafayette loses its all-day safe window in 6 months of the year — April through September — and October is not one of them. The year peaks in August at an average high of 91°F against 62°F in January, a 29°F swing that decides how much of the day belongs to your dog.
The nearest place we track is Baton Rouge, about 52 miles away. That is close enough to move together in a heat wave but far enough that a passing cloud bank or a coastal breeze can put real distance between the two readings, so check Lafayette's own page rather than assuming.
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 Lafayette 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.
