Waterproof car covers have become an essential accessory for motorists in recent years. While they provide exceptional protection against the elements, which is an increasing necessity in today's world, they also sometimes come with customer complaints: namely, heat. While users will come out to a dry, pristine vehicle, they'll usually have to “air out their cars” before they're able to drive them comfortably simply because the interior temperature has risen to such a high level. There are ways to avoid this though.

Coverage Time

For the most part, waterproof car covers are built to not allow penetration of any kind, which is what makes them waterproof in the first place. However, this restricted penetration also works on the other side – preventing heat from escaping through the top and allowing condensation to form. When this is the case, simply reducing coverage time and allowing the car to breathe can be a great way to reduce heat buildup in the vehicle in the short term. Something as simple as uncovering a car 20 minutes before driving it could be all of what users need to ensure they're comfortable in their vehicles while still getting all the benefits of a waterproof car cover.


Not all waterproof car covers were created equally. Some of the cheapest, most generic options are built as a solid cover with thick, readily available materials. Needless to say, these do nothing to allow internal heat to transfer back into the atmosphere. A more premium solution will be constructed with breathable materials that allow heat transfer while still retaining its waterproof qualities. The key to most of the premium options is in layering: that is, truly high-quality premium waterproof covers will be constructed with multiple layers using different materials to allow the vehicle to breathe.

Storage Options

While it's not recommended to store a car indoors without a car cover, keeping a car indoors can help control the ambient temperatures the interior of the vehicle is exposed to. Something as simple as taking it off the road and into a garage or even a covered carport can help reduce the internal temperatures by up to 20 degrees. Those who do choose to store their car indoors may also find that the reduction of UV exposure against the sun's finish helps promote a longer lasting shine along with decreasing paint fade over time.
