A fluid discharge nozzle 1 comprises a discharge tube 2 forming a fluid conduit for carrying fluid towards a discharge end of the nozzle 3. There is a pattern sleeve 27 displaceable between a first position which is relatively retracted in the longitudinal direction of the nozzle and the second position which is relatively extended. There is a baffle head 12 which comprises, on its underside, an annular fluid deflection surface 21 which is flat and extends in a direction substantially perpendicular to the longitudinal axis of the discharge tube. The baffle head is positioned relative to the pattern sleeve whereby in the first position of the pattern sleeve the fluid discharge from the nozzle is in the form of a spray substantially perpendicular to the longitudinal axis of the discharge tube and in the second position the fluid discharge from the nozzle is primarily a jet in the longitudinal direction. The baffle head is attached to an elongate stem 10, which reduces in diameter along the direction of fluid flow. There may be a spider 13 holding the stem in the discharge tube. The nozzle may be used for the purposes of fire suppression.
