Wisp Resort Closed For The Season 3/18/12. Wisp Resort Closed For The Season 3/18/12 as the springtime temperatures have finally decided to consistently stay warm enough to make snowmaking impossible. It has been a very successful winter for Wisp even though Mother Nature made them work harder than normal to keep snow on the ground. Thankfully the temps dipped periodically throughout the season, and when they did, Wisp was ready on every occasion to maximize their snow making efforts to keep excellent ski conditions throughout a very mild winter season. I talked to a lot of folks who weren’t complaining about skiing groomed corduroy trails with temps in the 50’s-60’s. Thanks Wisp Resort for a great winter season!
