Wind, rain, colder temps will effect turkeys. More often than not I've found it just delays their normal routines. Wind will force them to move to more of a sheltered area from the wind. Light rain they will be in a short grass/hay field. Heavy rain will put them deep in the timber somewhere they feel safe. Rain & wind effects their hearing just like it does ours. So if they can't hear they will go to were they feel safe. Cold doesn't effect them as much, I've noticed. It just delays them a little bit. Not everyday is going to be 70 and sunny, so a hunter needs to be able to adapt themselves to the weather and to what the birds will do in certain weather. The only way you can do that is be proactive and hunt/scout on inclimate days as well as nice days, to truly learn what certain birds do with certain weather. I hope this helps. Good luck! If you stick with it and be persistant you'll get one.
