Or maybe exactly accurate, if the density of water doesn't actually
change within that specific half degree temperature range when water
is at maximum density.

The density of water is dependent on its temperature, but the relation
is not linear and is not even monotonic (see right-hand table). When
cooled from room temperature liquid water becomes increasingly denser,
just like other substances. But at approximately 4 °C, water reaches
its maximum density. As it is cooled further under ambient conditions,
it expands to become less dense.

(Isn't Google marvelous?).
