This was the sight that greeted me this morning: the basin across the street had frozen over in a -6C overnight frost. Don't forget that this basin is tidal, connected to salt water etc. There was no wind first thing in the morning and a waferthin layer of ice had formed at high tide. The water dropped as the tide went out, leaving rocks, ropes and buoys clad in a gossamer layer of white. Just before midday, the wind started to pick up and the temperature rose from -2C to +4C (and stayed there all day), meaning the ice had gone after lunchtime.
