About this spot

About

Slaughterhouse (also known as Mokule'ia Bay) is a small, exposed Maui beach-break setting accessed by a steep concrete stairway down a roughly 100-foot cliff. While swell reliability is described as very consistent, the spot itself “does not work very often,” with many months producing either blown-out conditions or waves that are too small. When conditions line up for surfing, the spot is described as high-performance: a powerful, often hollow right-hand wave that can peel quickly along the eastern edge of the bay over a sand-and-reef mix. The working swell window is typically associated with North to Northwest swell, and the wave quality is described as excellent when it wraps into the bay. East and Southeast winds are reported to provide offshore conditions that groom the wave face. Safety concerns are a major part of planning here. Multiple sources highlight rocks and sharks as hazards, and for larger swell there can be strong rip currents along with a punishing, heavy shorebreak. Access and lineup require caution because of the steep cliffs and submerged rocks/reef sections (particularly toward the edges of the bay). Operationally, the location is difficult to manage on busy days: parking is limited along the highway shoulder and fills quickly on weekends and during peak season. The area is also within the Mokule'ia Marine Life Conservation District, where fishing and removal of marine life are prohibited—no fishing and no taking of coral or shells.

  • Very consistent swell reliability, but infrequent clean/waveable days.
  • Advanced-level right-hand surfing potential (powerful, hollow, fast).
  • Heavy shorebreak and strong currents when large swells hit.
  • Steep cliff access and limited parking.
