Above ground pool winter covers are used to protect the pool during colder months by limiting debris accumulation and reducing exposure to weather. These covers help support cleaner openings in spring by preventing leaves, dirt, and standing water from entering the pool. Winter cover selection is typically based on pool size, shape, and regional climate conditions. Winter covers are commonly installed as part of a complete closing process that includes pool closing kits. Many setups also coordinate covers with above ground pool equipment to protect exposed components. For added protection, winter covers are often used alongside above ground pool skimmers that have been properly winterized.
