A misting spray nozzle includes a hollow body having an interior wall descending from an upper end to a lower end. The interior wall tapers toward the lower end to form a choke. A channel section provides two fluid paths descending from an upper central aperture. A turbine is sized and shaped to fit closely within the choke and has spiral grooves on its outer surface. The turbine attaches to the body at its upper end and has a cone-shaped opening at its lower end. A conical core is sized and shaped to fit closely within the cone-shaped opening and has grooves spiraling in an opposite direction on its outer surface. The core is attached at its upper end to the turbine. The two sets of spiral grooves define a pair of intersecting fluid control paths that meet at the lower end of the body to create a dense mist.
