Can Saltwater Freeze?

Glad you asked...
Yes, seawater can freeze. The temperature needs to be about 4 degrees celcius to freeze. The more salt that is in the water the colder it needs to be to freeze.

Then again, this answer might help you...

It will freeze but it has to be a lot colder than normal water in order to freeze. Regular water will freeze at 32 F, Salt water has to be below -6 F before it will start to freeze.
