Resumo: The objective of this work was to determine periods of climatic risks for the sowing of the soybean in Conceição do Araguaia, in the southeast of the State of Pará, aiming to subsidize the local agricultural planning. The methodology took in consideration some aspects such as: water necessity of the crop, duration of the cycle and the phenological phases of the crop. Water balance simulations were also considered in order to determine water need indexs for the crop?s growing phase wich goes from floering to grain filling (crops water critical phase). The water balance had been carried through simulation of 72 planting periods between January and December, with level of retention in the in the ground of 70 mm and crop cycle of 120 days. The gotten results had show that the period between september and january is wath presenst minor climactic risk for the plantation of the soybean in Conceição do Araguaia.
