The density of water goes down when it is frozen and down when it is heated, so I would say just above freezing. According to the website, about 4 degrees C. The density of water at this temperature is 1.000g/cm3

Water is unique in that it is most dense as a liquid. In fact, it is most dense at about 4ºC and it's density is exactly 1 g/cm^3 (by definition).
It is this unique property of water that allows fish to live during the cold months...if ice were more dense than water, ice wouldn't float and would cause all sorts of ecological issues with the oceans near the poles and on lakes/ponds that freeze over.

Water is at its most dense at 4C, when it's density is exactly 1g/cm3 - do you get the feeling you just hit on the basic definition of a gram? Cause you did!

H20 is most dense at absolute zero
