That was what happened during our stay in Glanz Carinthia. We booked months ahead only to have rain the whole week , we packed our bags and went home. Good that we did not book for the 1st week of July because they had flooding and tourist were stranded. The mountians there were high like 2000 -2500 meters above sea level and are skiing areas.
The micro climate helps the area to be lush, but also extreme humidity can also be a nuisance.
You can rarely have your cake and eat it too, definitely some challenges living in extreme microclimates.
