Inflatable Christmas ornaments designed for outdoor display are generally waterproof and durable. Usually designed with synthetic materials, like nylon, these inflatables can sit in both rain and snow.
Regardless of their actual shape and size, their weather-resistant material sheds water easily, keeping moisture from seeping inside. For those with internal fans, this is especially important.
You will want to take certain precautions, however, to ensure your inflatable Christmas ornaments last a long time and still look their best. Avoid placing them near downspouts or cascading gutters and away from areas that flood or where water tends to pool.
If a severe storm is forecasted, bring your inflatables indoors or place them in a garage or other covered structure until it is safe to return them to their designated spots. If they’re accidentally left outdoors during inclement weather and the fan quits, move them under shelter and allow them to dry and drain.
