A lot of it depends on what's normal for where you fly. Here in Oklahoma (yes, the wind really does come sweeping down the plains) we're used to flying in the wind. A normal day for us is 10-20 mph. 20+ is getting windy. and 25-30 is pack it in. I've flown in wind up to 40 before.

Then funny things is when we have a windless day here. None of us can land worth a darn. We're so used to having wind to slow down our planes that when there isn't any wind we are always overshooting the runway!!
