Vinyl fences can sway in high winds like any other type of fence. However, vinyl fences are generally more wind-resistant than other types of fences, such as wood or chain-link fences.

The amount of sway that a vinyl fence experiences in the wind depends on different factors, including the height and design of the fence, the spacing of the fence posts, and the severity of the wind. Generally, taller and narrower fences will experience more sway in the wind than shorter and broader fences.

To minimize the amount of sway a vinyl fence experiences in high winds, it is important to ensure that the fence is properly installed and the posts are anchored securely into the ground. Additionally, adding reinforcement to the fence posts, such as steel posts or concrete footings, can help to make the fence more wind-resistant.
