How long can a car stay in garage if temps drop below freezing

Next two nights temps here are supposed to drop down into mid 20’s one night, upper 20’s the next night... low to mid 40’s in the daytime, before temps warm back up again.
Just wondering with just water in it, if a few hours will cause any issues where it dips below freezing
TIA

EDIT: Just saw where you are... so my post might be silly since you do the same thing in the winter...

EDIT2: Some problem with antifreeze? Just curious...

Having grown up in MN, I'll say you're good to go. I parked outside with 20 or more below regularly.

You saying all you have is straight water?
