Daylight time will be approx. from 8.00am to 5 pm - depending on weather conditions. It tends to be quite damp and cold during this time of the year - fog, rain or sleeze, sometimes snow. Temperatures around the freezing point to slightly plus.
No need to be stuck anywhere if you bring the right clothes (warm anorak, warm boots, mittens, hat) and the right attitude - there is no bad weather, just insufficient gear. Possibly too early for skiing anyway so I would rather suggest a city break in Vienna, where there is a lot to do and to see indoors.
