Design compatible with the climate means maintaining the micro-spatial condition of the housing within the range of comfort. Therefore, for sustainable architecture, it is necessary to know the climate correctly and create a proper adaptation to it. On the other hand, with the excessive increase of fossil fuels in buildings in order to create cooling, heating and ventilation, the approach of sustainable architecture appeared with the aim of using as little non-renewable energy as possible. One of the most important points influencing this approach is familiarity with the climatic characteristics and weather conditions of the city and how to deal with these factors. The purpose of this article is to identify and investigate the climatic conditions of Mahabad city in West Azarbaijan province, which has had a noticeable physical and physical expansion in recent years, and to continue to provide architectural solutions that are appropriate to it with the approach of architecture and sustainable housing design. In this research, the required climatic statistics during a period of 51 years (1959-2010) were extracted from the website of the Meteorological Organization, and then relevant processing was done on the raw data. The research method is descriptive-analytical. The results of the research indicate that in the city of Mahabad, in most months of the year, the cold air has caused people's dissatisfaction, and the high temperature during summer days and the cold air in other months of the year, especially during the night, cause thermal dissatisfaction in the city of Mahabad. will be
