I think you are referring to the water that is blown up into the air as a whale 'blows' air out of it's blow hole--it's not actually the whale's breath. This is called a spout.
whales Breathe with lungs
Whales have lungs and come to the surface to breathe. Their nostrils called blowholes are located on the top of the head to access air easily. Whales exhale, condensation from the 2 blowholes forms a 'v-shaped' 'blow'. when they submerge they hold their breath.
