It is 4°C.
Density is inversely proportionate to Volume.
With decreasing temperature, up to 4 degree Celcius, the volume of a particular amount of water shrinks and the speed of molecular movements decreases. So, the density increases gradually.
At 4 degree celcius the density becomes maximum while it is in liquid state.
Below 4 degree Celcius, water molecules start occupying crystal structure and while reaching solid state, the distance among one another increases than previous. Hence with further decrease in temperature below 4 degree Celcius, the volume slightly increases and the density decreases.
One example is:
In countries falling under sub-polar and polar circles, water pipes often crack as water becomes ice in cold temperature. It means ice has more volume than its equivalent amount of water.

27 degree or more than is temperature where liquid have have higher density if it goes lower it starts to freezing it become ice and it starts to floats.
hope it's helps.
