Thanks Heinz. There are some conflicting factors this year with crowds. Right now I expect things to be very quiet. However, we are now seeing Covid cases start to plummet in the UK and I expect we will see the same in Europe very shortly with significant pent-up demand to go skiing suddenly being released! having said that, maybe there are plenty of europeans who've already written it off as an option this year.I think @Skifahrer would be able to give a good answer for Austria being a regular seasonal skier there. When I go it is more often from mid March and fingers crossed this will be the case again this year. Once the school holidays are done in February the main crowds do drop off with just another short peak over Easter. Snow conditions in Austria in March and into April are still very good, less frequent powder, but normally still good coverage form earlier season snowmaking.
I quite enjoy spring skiing in Austria. Much less crowded, good weather so you can sit outside at the huts for lunch. You will do more of your skiing higher up but most areas will try and make sure they have a skiable valley run (Talabfahrt). It is a relaxed atmosphere.
Obviously with Covid crowds will be much less than usual which @blueandwhite reports confirm. Suspect even in school holidays there won't be quite as many German families visiting.
