It is due to the hydrogen bonding between water molecules.

Explanation:

The initial addition of thermal energy is needed to break the hydrogen bonds between water molecules. Additional thermal energy is necessary to bring the water to a boil. If water molecules did not form hydrogen bonds with each other, the boiling point would be much lower, and we may not have liquid water on the earth.
