actually it's 3.98 celsius according to lange's

 

interestingly enough you can calculate water's max density at a given pressure (var "p" in atmospheres) by the equation:

tm=3.98-0.0225(p-1)

 

but yeah, at higher temps collision rates increase, thus making it less dense. you would think that the greatest density would be the positive limit as the temperature approaches 0 (yeah calculus) but instead, since water doesn't all melt just above 0 celsius, 3.98 celsius is the temp at which the maximum density is achieved
