The heat is not only tough on people, but on our pets too. Different materials heats up quicker and better than others. It all depends on the material’s heat capacity. Asphalt has a large heat capacity, and so does concrete. Color plays a role too. White for example, has a high albedo, and reflects a lot of solar radiation. Snow reflects a lot of solar radiation, and can keep temperatures cool for a while.
Shaded areas can be roughly 25 degrees cooler than concrete, and 40-50 degrees cooler than asphalt. Depending on the age of asphalt, the shade and temperature can vary as well. The temperature of asphalt can surpass 140 degrees when the air temperature is 90 degrees. It can surpass 120 degrees when the temperature is near 80 degrees, which is hot enough to burn the paws of your pet.
Dry grasses, that are out in the open can be around 10 degrees warmer than the air temperature, shaded grassy areas can be several degrees cooler than the air temperature. You can purchase a thermometer gun at a local home goods store.
The pavement is still likely hot at 7pm, but as the sun goes down it will get better. Overnight lows are usually met near sunrise.
