Question on the weather/activities at X-mas time in Vienna, Budapest, Prague, etc...?

[Live the good life]

We will be on a Christmas time River cruise from Prague to Vienna with pre-cruise stay in Amsterdam and post-cruise stay in Budapest.

 

Wondering what the weather would be like during this time of the year in Amsterdam, Prague, Vienna, Salzburg, and Budapest? We have only been to Paris, Barcelona, Madrid during X-mas times past years; and besides being at the Whistler ski resort in Canada, are usually at a warm places during this time of the year...

 

Wondering whether there will be Snow? whether the river will be partly frozen? Will the monuments be covered in snow or only for a few hours in the morning?

 

The average weather record lists about 37 degree F, and one hour of sunshine average a day during December. Will one still be able to take photos of monuments during the day time? Also, will there still be musicians on the street performing, and activities at outdoors shops/cafes (besides X-mas markets), or will most activities be limited indoors?

 

Thanks for any input,

 

Kim
