Abstract : Field studies were conducted to make the agroclimatic zoning of mango crops in Piauí, Brazil. The average annual data of precipitation and air temperature of 15 cities in Piauí were utilized representing the main regions of the state for the elaboration of the water balance and attainment of the moisture index. The following bands of moisture index had been adopted (Im): full aptitude A, Im -40; and full aptitude B,-40 Im -20. The criterion utilized in the division of the state in thermal areas was based on the normal temperatures measured of the hottest month (Tq) for each place. Then, the bands A and B with full aptitude of the hydric point of view were subdivided in 2 subareas: full aptitude A1 (Tq 29°C) and full aptitude A2 (29°C Tq 31°C); and full aptitude B1: (Tq 29°C) and full aptitude B2 (29°C Tq 31°C). Based on the letters of Tq and Im, the limits for different climatic areas of aptitude for the mango crop were defined. Based on the used criteria and on the consulted literature, the state of Piaui does not present none climate restriction for commercial mango cropping.
