Now to some of you... yes water freezes at 32 but it does not freeze instantly it takes time to cool off and does not freeze HARD that fast... and it is the hard freeze that hurts you.
It is the hard freeze that hurts you. You would not evan think of going out on a pond if it hit 31 degrees overnight. It needs a long sustained freeze to make it safe. I have never had any issues when in the mid 20's overnight. But if it does not go above freezing during the day, and will be below freezing for two or three days straight, i would be doing something.
