A swimming pool debris screening assembly for preventing clogs in a pool's water flow system includes a bracket that is sized to partially insert into an inlet of a pool skimmer of a pool. A first section of the bracket is frictionally coupled to the inlet and a second section of the bracket extends from the inlet into the pool. A grate is selectively couplable to the second section of the bracket so that the grate is configured to screen debris from water that enters the inlet.
