Summertime: How High Can the Temperature Get Inside My Car?

During the summer, we know temperatures rise in our vehicles, especially if we don’t use sun shades or place towels over seats to keep them from getting hot. Unless you make extra efforts to garage park or keep your car in the shade, there can be health consequences.

Heat Kills

Every year, pets and children die from heatstroke when left inside a parked car during hot summer months.

Once the air conditioning is turned off, the interior temperature of a car rises quickly. As UV rays pass through the glass, they warm the interior, heating the dash and upholstery. In less than five minutes interior temperature can hit 90 degrees Fahrenheit or more. Heat, trapped inside the car, increases rapidly.

This table illustrates how quickly a car’s interior can get dangerously hot.

What If I Crack the Windows?

Cracking the windows does allow for more airflow, but the change is so small that it does not make any real difference. According to a 2005 study by the American Academy of Pediatrics, in 72 degree weather the temperature inside a car can rise 40 degrees within an hour.

Kids and Pets

Children are especially vulnerable to heat and cannot tolerate it as much as adults can. Pediatricians and police officers strongly recommend that drivers never leave a child or pet alone in a car, even for “quick stop.” Small children generally do not have the ability to free themselves when the temperature becomes dangerous.

Pets are more vulnerable to heatstroke and death than children. Cats and dogs do not sweat. They pant to cool themselves. The hot air inside a car can quickly kill an animal.

The Windshield

Your windshield is specially treated to protect you from the sun’s ultraviolet radiation, but the side and back windows are not. Dermatologists notice consistently more skin damage on the left side of most people’s bodies than the right. This is due to sunlight exposure while driving. In countries where the driver is seated on the right, there is more skin damage on the right.
