No.
When i go ice fishing holes I drill in the morning are often frozen by the afternoon. And that isnt at particularly cold.
The implication I got from the show is that they spent one night (waking up, finding Thoros frozen).
A small hole you drill for ice fishing is not the same as a large ice sheet freezing enough to support thousands of men.
