Climatic conditions are important and effective parameters in bio-comfort in human environments. Given the climatic conditions, the architecture of the building has long been paid much attention since it can provide humans with more comfort. For example, vernacular and traditional architecture in different countries and regions of the world, especially in our country, is rich in experiences and samples that represent precise solutions for adapting the physical spaces to the climatic conditions. These solutions led to buildings and living spaces which have been quite successful in adapting to the natural environment, exploiting the natural energies, and dealing with the adverse and very hard climate conditions. The southern coasts of Iran, which are separated from the central plateau by the Zagros Mountains, form the hot and humid climate of Iran. This climate is characterized by very hot and humid summers and temperate winters. The cities of Bandar Abbas are considered some of the big cities which are subjected to this climate. Accordingly, the city's climatic characteristics have significantly affected its formation. Therefore, the present research has aimed to investigate the climate impacts on the architecture of Bandar Abbas, using the methods of Algi, Givani and Mahani. Finally, some appropriate solutions were provided for the compatibility of the climate and architecture in the city.
