Developing and using of the renewable energy in the world has been increased and it is one of the most important factors to reduce fossil fuel. Among renewable energies wind energy is a well-known and important energy for electrical production .Present study shows wind energy potential in Dayyer port that is a city in Bosher province. First, collected data from meteorological organization was belong to 2011-2014 periods and in 10 m high above ground level. Then calculated mean wind speed then wind potential by Weibull function density and power of wind measured.
