Strong waves strike on winter-swimming stairs

After knee joint rehability day I went to bath to the common sauna of Kaupinoja, +80c.
Wind 10m/sec temperature +7c but feels chilly.
Lake Näsijärvi +10c.

You could not swim in this kind of waves, of course, but if you did hold on tight, you could dip. If there would have been more light, most of the people would have not dipped either. Me and my daughter did dip three times there. 

Backblipped.
