Excessively cold temperatures can damage pool linings, including in models like our favorite overall pick, the Intex Ultra Frame. Inflatable pools should also be deflated and stowed for cold weather. However, many resin or steel-framed pools are designed to withstand year-round weather, so it's best to check with your pool's manufacturer. Even winter-capable above-ground pools will likely require a "winterizing" process, such as draining all pumps and hoses.
