Since the date is somewhat later than usual, we can't guarantee there'd be any snow to roll in naked in between the sauna. The ice hole may also have melted to cover almost the entire lake, which allows for longer swimming trips. The water will probably be about +5 centigrade for a refreshing dip.
So far we haven't had much snow this winter, so there is a slight possibility that it'll all rain down in spring. Water in any form won't stay up in the skies forever, so anything between thigh-deep snow to budding coltsfeet is possible. Come and see for yourselves!
