A carport is a shelter and an alternative to a garage. The great thing about it is that it can be set up without special equipment and is relatively cheap. It tends to be open air, but that is fine if all you want is to keep the rain and snow off your vehicle. A carport made with steel tubes and an aluminum roof is convenient. A carport made with easily collapsed PVC tubes and a fabric cover is even better if it is not expected to stay in place for years.
Get your portable carport from a website that loves to sell such unexpected and useful products. It is like a gazebo for your car. The fabric might even close shut in order to partially block the wind. Something like this can protect your vehicle or else provide shelter that is more solid than a tent.
