The temperature inside a car can skyrocket, even on mild days, posing significant risks to passengers, especially children, pets, and the elderly. When the outside temperature is a pleasant 68 degrees, it’s easy to assume that the inside of a car would remain relatively cool. However, this assumption can be deadly. In this article, we’ll delve into the factors that influence the temperature inside a car, explore the risks associated with overheating, and provide valuable tips on how to stay safe.
Understanding the Greenhouse Effect in Cars
The greenhouse effect is a phenomenon where the interior of a car heats up due to the sun’s rays penetrating through the windows. This occurs because the sun’s short-wave radiation easily passes through the glass, while the long-wave radiation emitted by the heated interior is trapped, causing the temperature to rise. The color of the car, the type of windows, and the presence of window tints or shades can all impact the degree to which the greenhouse effect occurs.
Factors Influencing Temperature Increase
Several factors contribute to the temperature increase inside a car, including:
- Time of day: The temperature inside a car can rise rapidly during the peak sun hours, typically between 11 am and 3 pm.
- Orientation of the car: A car parked in a direction that receives direct sunlight will heat up faster than one parked in the shade.
- Color of the interior: Dark-colored interiors absorb more heat than light-colored ones, contributing to a higher temperature increase.
- Outside temperature and humidity: While 68 degrees may seem mild, high humidity can exacerbate the heating effect, causing the interior temperature to rise more quickly.
Temperature Increase: A Closer Look
Studies have shown that, even in mild weather, the temperature inside a car can reach extreme levels. For example, a car parked in direct sunlight on a 68-degree day can reach temperatures of up to 120 degrees in just 30 minutes. This rapid heating can be attributed to the greenhouse effect, conduction, and convection, which work together to trap heat inside the car.
Risks Associated with Overheating
The risks associated with overheating in a car are very real and potentially deadly. Children, pets, and the elderly are particularly vulnerable to heat-related illnesses, including heat exhaustion and heatstroke. Leaving a child or pet unattended in a car, even for a short period, can have devastating consequences.
Heat-Related Illnesses
Heat-related illnesses occur when the body is unable to cool itself properly, causing the internal temperature to rise. This can lead to a range of symptoms, including:
Symptoms of Heat Exhaustion
Heat exhaustion is a milder form of heat-related illness, characterized by symptoms such as:
- Heavy sweating
- Pale skin
- Fast and weak pulse
- Nausea or vomiting
- Dizziness or fainting
Symptoms of Heatstroke
Heatstroke is a more severe and potentially life-threatening condition, marked by symptoms such as:
- High body temperature (above 103 degrees)
- Confusion or slurred speech
- Seizures or loss of consciousness

How hot can a car get in 68-degree weather?
The temperature inside a car in 68-degree weather can soar to extreme levels, even if the outside temperature seems mild. This phenomenon is due to the greenhouse effect, where the sun’s rays enter the vehicle through the windows and are trapped inside. As a result, the temperature inside the car can rise to 20-30 degrees higher than the outside temperature. For instance, if the outside temperature is 68 degrees, the inside temperature can reach up to 88-98 degrees Fahrenheit within a short period.
It’s essential to note that the rate at which the car heats up depends on various factors, including the color of the vehicle, the type of windows, and the amount of sunlight it’s exposed to. A dark-colored car with tinted windows will heat up faster than a light-colored car with regular windows. Moreover, if the car is parked in direct sunlight, the temperature inside will rise more quickly than if it’s parked in a shaded area. It’s crucial to be aware of these factors to take necessary precautions and prevent any potential risks, especially for vulnerable individuals like children, pets, or people with certain medical conditions.
What are the risks associated with a hot car in moderate weather?
The risks associated with a hot car in moderate weather are significant and should not be underestimated. One of the most severe risks is heatstroke, which can occur when the body temperature rises too high. Heatstroke can be life-threatening, especially for children, pets, and people with pre-existing medical conditions. Additionally, a hot car can also cause dehydration, dizziness, and disorientation. If a person is left inside a hot car for an extended period, they may experience symptoms like headaches, nausea, and fatigue.
It’s also important to note that the risks are not limited to human health. A hot car can also damage the interior and exterior of the vehicle, causing the dashboard, seats, and other materials to degrade over time. Furthermore, a hot car can also pose a risk to pets, who may be left inside the vehicle without adequate ventilation or water. To mitigate these risks, it’s crucial to take precautions like parking in shaded areas, using sunshades, and never leaving vulnerable individuals or pets unattended in a hot car.
How long does it take for a car to cool down in 68-degree weather?
