This study aimed at accomplishing the agroclimatic zoning of Pernambuco State, in order to provide subsidies for the selection of areas for implantation of Alpinia purpurata tropical flower. The climatic data of 123 localities (69 with a period above 30 years and 54 below 30 years) were used, thus getting a better representation of the data in the state. From climatic data of the average temperatures of air and rainfall, the climatologic water balance has been calculated. The cities of Igarassú, Primavera, Goiana and São Lourenço da Mata were chosen to be climatic representatives as they are the producers of the species in Pernambuco. By having the data of the water balance and the minimum and maximum air temperatures, the indexes of thermal and water limit in relation to the requirements of the species in the representative cities has been estimated, and only after this the indexes were extrapolated for the whole State. In accordance with this study, Pernambuco presented 6 localities with full suitability, 16 with regular suitability and 101 unsuitable for the cultivation of species.
