Taylorsville Police Chief Dennis James is reminding the public to never leave a person or a pet inside a car in the heat of Summer.
James says his officers have responded a number times over the course of the recent hot weather to reports of people or pets in a parked vehicle with windows rolled up and no air conditioning running. Even if you plan to be away from the vehicle only a short time, it takes very little time for the temperatures to start climbing.
So how high can the temperature inside your car go?
The exact answer will vary, of course, depending on the type of car, where it is parked, the time of day, etc. But there have been several studies to find the average temperature increase, and the results are uncomfortable:
The fastest temperature rise occurs in the first few minutes. Within just 10 minutes, the temperature can increase between 10 and 20 degrees.
Over the first 30 minutes, the temperature increases by an average of over one degree per minute. If you park and go inside a store for 30 minutes on a 90-degree day, you’ll come back to a car that is over 120 degrees.
After one hour, the average car is 43 degrees hotter than the outside temperature.
After 90 minutes, the average temperature difference is 48 degrees. On a 90-degree day, that equates to 138 degrees—higher than the hottest outdoor temperature ever recorded on earth.
Interestingly, these temperature increases are roughly the same no matter what the outdoor temperature is. Even on a beautiful 75-degree day, the temperature after 90 minutes will be over 120 degrees.
