Boiling water is water that's bubbling at 212ºF. ... Simmering, on the other hand, is slower than that nice bubbling boil. It's still very hot—195 to 211ºF—but the water in this state isn't moving as quickly and isn't producing as much steam from evaporation. Simmering water is great for soups, broths and stews.
