Full Answer

The range of cold water temperatures is considered to be from 32.5 degrees Fahrenheit to roughly 70 degrees. As water temperature falls, a person's ability to survive before hypothermia and unconsciousness set in decreases. In 32.5-degree water, a person will only be able to remain conscious for roughly 15 minutes. If the temperature is between 50 and 60 degrees, the person can remain conscious for 1 to 2 hours. In water temperatures above 80 degrees, a person can survive indefinitely.
