Although the behavior of rain drops near the surface of a building in driving rain are quite complicated according to the sizes of the drops and the air flow pattern around the building, a general relationship exists between average impinging angle of raindrops against the wall surface and the wind velocity that accompanies the rain. It can be of great value in estimating wetting characteristics of those walls, if we can express the relation in a simple equation. Shapes and sizes of stained areas that are left just below projections over a wall offer valuable information for the maximum impinging angle of raindrops against the wall. From the analysis of wind speed records during the rains which could have caused the stain patterns, certain range of constant C_<im> for the impinging angle-wind velocity equation was obtained.
