Incoming water temperature can be effected by some things. When I lived in town I'm not sure what temperature the city water supply was but it was warmer than the water I pump out in the country that is coming directly from the well. That city water warms up some while in the lines vs being used right after it is pumped. During periods of high use in town - like during hot and dry weather and lots of people are watering lawns I had noticed the water was colder - it was not in the lines for as long.
Most municipalities use above ground storage tanks, (towers) if usage is low, this allows the water to be be warmed or cooled by the ambient air temps, with private well systems, most of the water storage is underground, with a small amount in the bladder tank under or above ground, usually in a insulated enclosure to prevent winter time freezing. Tankless waterheaters do not work well on private well systems, as the water pressure does not remain constant which varies the temp of the water. (I know, because I have a gas fired tankless) Most have flow and temp sensors that adjust for this, but do not adjust fast enough to keep the water an even temperature.
