How High is the Surface Temperature of a Car in Summer?

In many cities, the outdoor temperature can reach up to 40 degrees Celsius during summer. If a car is exposed to the sun for a long time, the interior temperature can exceed 70 degrees Celsius, which is extremely high. Prevention and Rapid Cooling Methods: Try to park the car in a shaded area where it is not directly exposed to sunlight. If parking outdoors, use a car cover or apply a reflective sunshade film on the windshield. When the interior temperature is high, you can open the car doors, spray water inside, and then turn on the air conditioning to cool it down. Dangers of Excessive Temperature: When the temperature reaches 41-42 degrees Celsius, it is the upper limit of human endurance. Prolonged exposure to such temperatures can pose severe threats to life, as the body's metabolic systems, including sweating, breathing, and blood circulation, may fail. Individuals with weaker constitutions are at risk of accidents at any time.

The temperature on the car surface in summer is really high. Yesterday I drove to the supermarket and parked my car under the scorching sun for just half an hour. When I came back, the hood was so hot that I couldn't even touch it. I measured it with a thermometer - while the outside temperature showed 35°C, the car surface, especially the black parts, reached nearly 70°C. This is mainly due to direct sunlight, as car paint and metal have strong heat absorption capacity but slow heat dissipation. Dark-colored cars get even hotter, while light-colored ones are slightly better. Also, tire surface temperatures get extremely high, which can accelerate wear. I suggest friends try to park in shaded areas or underground garages when possible, and don't let children touch hot car surfaces to avoid burns. Using sunshades can help reduce temperatures somewhat, but the safest approach is to finish errands in the morning and drive away quickly.

Every time I take my child out in the summer, I worry about the surface temperature of the car. Last Sunday, when the temperature was only 32 degrees Celsius, I parked in the sun for 20 minutes, and the door handles were too hot to touch, probably over 50 degrees. Darker areas like the rearview mirrors were even hotter, reaching 60 to 70 degrees. This heat not only burns but also causes the interior air temperature to rise, making my child complain about the heat as soon as they get in the car. I usually start the air conditioning remotely 10 minutes in advance or use a wet cloth to wipe the car surface for a quick cool-down. The key is to avoid parking outdoors for too long in hot weather, and choosing silver or white paint can help keep the car cooler. Stay safe and beware of heatstroke.

I've measured the surface temperature of cars several times, and it's quite interesting. I have an infrared thermometer and tried it out at noon in an open parking lot during summer. The ambient temperature was about 30°C, the light gray car hood showed 45°C, while the dark blue car roof soared to 58°C. Color and material make a big difference, with black absorbing heat the fastest. Temperature changes are rapid too, rising by 10°C in just five minutes under sunlight. When parking, try to choose shaded areas or use reflective heat-insulating film on the paint surface. Simple DIY methods can protect the car paint from aging. Excessive heat can also shorten tire lifespan, so regular checks are recommended.

As a seasoned driver, I've seen many issues caused by summer heat in cars. The surface temperature of a car changes with the weather, often reaching fifty to sixty degrees Celsius or even higher under direct sunlight on hot days. I remember one year when the temperature hit 40 degrees, the car hood was so hot you could fry an egg on it, with actual measurements exceeding 70 degrees. This not only causes discomfort but also accelerates paint cracking and the aging of rubber components. I recommend frequently rinsing the car with cool water to lower the temperature, but avoid splashing cold water immediately as the sudden temperature difference can damage the car. When parking, choose a north-facing spot or a shaded area to help the interior cool down faster. My experience suggests leaving early to avoid the midday heat peak and not to overlook the hidden dangers of high temperatures on the car's surface.

Why is the surface temperature of cars so high in summer? Let me explain the reasons behind it. The infrared radiation from sunlight is absorbed by the car body, with black metal parts reaching 60-70°C, which is 20-30°C higher than the ambient temperature due to slow heat dissipation. Lighter-colored cars reflect more sunlight and thus have slightly lower temperatures. I've measured it outdoors—the hood can heat up to between 50-70°C, depending on sunlight intensity and duration. This heat affects driving comfort and may even cause plastic parts to deform or skin to burn. It's recommended to use sunshades or periodically move the car to ensure a safe and comfortable trip.
