A vent cover for covering an opening in a building structure to vent its interior is provided. The vent cover includes a hollow cover member with an open bottom for positioning over and covering the opening in the building and a front end with an opening. A grill is removably secured in the opening in the front end of the cover member. The grill has a plurality of partitions. Each of the partitions is defined by intersecting members, which have a tapered cross section for accelerating the flow of air through the grill. The grill also has a splash guard and an overhang structure optimal for preventing rain, snow and water from entering the grill and the opening in the building structure. The cover member may be aerodynamically shaped for use atop vehicles such as trailers and RVs.
