Wind, especially when combined with unseasonably cool temps and damp conditions, will normally suppress gobbling activity, but 5-10 mph is not that windy. I would say that you would need 20+ before it starts to impact them much.
That being said...I have snuck quite close to gobblers on the roost while it was windy, it helps to cover your sound. They may not gobble as often when windy, but normally they still will sound off often enough early in the AM to let you know where they are.
