Investigating of the lateral force on structures under wind loading is very important, especially in the analysis and design of wind-sensitive structures and structures located in windy areas. In the building design regulations, the basic wind speed in each area is presented as a basic parameter for the initial estimation of the amount of load on the structures. Due to the lack of provision of the basic wind speed in the latest edition of the sixth topic of the National Building Regulations for the region of Namin city and considering the establishment of meteorological stations in the aforesaid region. In the present work, the wind speed data was investigated in terms of probabilistic distribution and the determination of the return period. The results show that the prevailing wind direction in Namin region is from the east. The maximum annual wind speed is 17.7 m/s and the average annual wind speed is 30 m/s. Also, Weibull, Log-Normal, and Gamble distribution functions have the highest compatibility with the investigated data, respectively. The basic wind speed of Ardabil station is 38.9 m/s according to the latest edition of the sixth topic of the National Building Regulations (which is the closest station to Namin city area used in the analysis and design calculations of structures under wind loading). Based on the data available in Namin city, the basic wind speed is 31.28 m/s with a return period of 50 years, and it is less than the value mentioned in the sixth topic of the National Building Regulations.
