REEF3D uses the Cartesian system. The direction is the angle between the vector and the positive x−axis, measured counterclockwise, representing the direction where the waves are going to.

Your angle of 295 northwest is probably by the Nautical system, where the direction is represented by the vector from geographic North measured clockwise, representing where the waves are coming from.

So 295 degrees in the Nautical system should be -25 degrees (or 335 degrees) in REEF3D per Cartesian system.
