The average temperature of drinking water can vary depending on the season, the place where the temperature is taken, and several environmental conditions, such as the presence of industrial facilities and natural bodies of water.
Temperature differences between tap water in the northern and southern states can range from 6 to 10 degrees. In northern areas such as Michigan and Vermont, the average water temperature is 45,1 degrees Fahrenheit. 50 degrees Fahrenheit is the typical temperature of cold drinking water in southern states such as Florida and Alabama.
The outdoor temperature has the greatest influence on the temperature of cold tap water. Due to the fact that it is merely filtered through a plumbing system and not heated in a hot water heater, it can fluctuate based on the outdoor temperature. Generally, if the actual faucet of the sink has been left in the sun or exposed to heat, the temperature of the cold tap water will be changed, but it will return to a more moderate level. Due of their greater susceptibility to heat, many older faucets deliver cold water that is warmer.
