Mathematical Modeling provides modeling of everyday situations for better interpretation of events. Also, it contributes to academic development and search for solutions in order to facilitate problems in different areas. To make better use of water resources in the region, this study aimed to determine the monthly mean reference evapotranspiration (ET_0) by the Penman Monteith method. The radiation balance (R_n) corresponded to 59.0% of the average value of global solar radiation. Evapotranspiration ranged from 6.82 mm/day to 2.57 mm/day, obtaining the highest coefficient of determination with net radiation where R^2 equals 0.682. In the interval between 3.5 and 5.5 mm/day a considerable sample of the reference evapotranspirations occurring in Januária (MG) is concentrated.
