Hydrodynamic characteristics are important considerations in the design of cages used for fish farming nearshore marine environments. The hydrodynamics sites mangrove creeks and comparatively open water channels Kilifi Kwale Counties Kenya were sampled across tidal cycles seasons using an Acoustic Wave Current Profiler (AWAC). Water temperature ranged between 25.9 °C 33.0 °C, was lower deeper areas with larger heights than shallower smaller heights. column height 9.68 - 14.69 m at Kijiweni, 1.16 6.7 Kibokoni Tsunza, 0.72 2.57 Dabaso.
