Abstract

A rain gauge is disclosed and includes a collection cylinder and a rain gauge head. The rain gauge head includes an intake opening and a vane tail, with the vane tail redirecting the intake opening to face oncoming wind and rain so that the intake opening collects oncoming rain. The rain gauge head includes a rainwater discharge to deposit rainwater within the collection cylinder. The rainwater discharge may be rotatably fastened to the collection cylinder so that the rain gauge head is free to rotate around a vertical axis for 360 degrees. Alternatively, the rain gauge head and collection cylinder may rotate in unison. An air exhaust port and air pressure relief valve may be formed in either of the rain head gauge or collection cylinder to release air trapped within the rain gauge. Airfoils may be placed on the collection cylinder to better redirect the rain gauge.
