As whales reach the water surface to breathe, they forcefully expel air through the blowhole. The exhalation is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses. This spout, known as the blow, is often visible from far away as a white splash, which can also be caused by water resting on top of the ...
A blowhole system always contains three main features: a catchment entrance, a compression cavern and an expelling port. The arrangement, angle and size of these three features determine the force of the air to water ratio that is ejected from the port. [6] The blowhole feature tends to occur in the most distal section of a littoral cave. As ...
Spouting Horn is a blowhole located on the southern coast of Kauai in the Koloa district. This area of Kauai is known for its crashing waves (nearby Poipu translates to "crashing" [ 1 ] ). These waves erode lava rocks on the coastline which can create narrow openings, as is the case with Spouting Horn.
The sea cave and the land surface become conjoined when the roof of the cave collapses. Blowholes are formed by the process of erosion. When waves enter the mouth of the cave they will be funneled up towards the blowhole, which can become quite spectacular if the geometry and state of the weather are appropriate.

[4] Hālona Point is a tourist spot, with visitors coming for the scenery, the beach at the cove, and in the winter as a spot to go to see humpback whales or Honu turtles (Hawaiian Green Sea Turtles).
