Understanding the factors that contribute to this rapid heating is the first step in mitigating potential damage and ensuring safety.
1.1. The Greenhouse Effect in Your Car
The greenhouse effect is the primary reason why cars heat up so quickly. Sunlight enters the car through the windows, and much of this energy is absorbed by the interior surfaces like the dashboard, seats, and floor. These surfaces then re-emit the energy as heat. However, the car’s glass windows are not transparent to this heat radiation, trapping the heat inside. This trapped heat accumulates, causing the interior temperature to rise far above the outside temperature.
1.2. External Temperature and Time
The outside temperature plays a significant role in how hot your car can get. On an 80-degree Fahrenheit day, the interior of a car can reach 109 degrees Fahrenheit in just 20 minutes, according to the CDC. After 40 minutes, it can hit 118 degrees, and after an hour, it can soar to 123 degrees. In hotter climates, like Phoenix, where temperatures can consistently exceed 100 degrees Fahrenheit, the interior of a car can reach even more dangerous temperatures in a shorter amount of time.
Table: Temperature Increase Over Time
| Time (Minutes) | Outside Temperature (Fahrenheit) | Inside Temperature (Fahrenheit) |
|---|---|---|
| 0 | 80 | 80 |
| 20 | 80 | 109 |
