If you have been successful previous years with winterizing a certain way, under certain conditions and when temps were a certain degree etc. then maybe wait until those same conditions etc. are present... It will be just later in the year or next year.

I have the same problem here with the temps but it's too late for me. I had already put mine in their winter protection when it was very cold a couple of weeks ago. Now it's in the 50s & 60s! There isn't much I can do about it now except wait and see what happens. If you can wait a while longer without it being a problem I would say do so. If you can't wait just do it and hope for the best. Amazingly they manage to survive even our worst efforts, lol!
