Fresh water freezes At 32° F 0°C

If you had water saturated with as much salt as it could hold the freezing Temperature would be Around -21°C -6°F

The reason this is mentioned is to take into account sea water. And Even then you should look up a salinity psu chart to Figure out more exact temperature's according to the salinity of the water.
