Multiple regression equations to estimate mean monthy and annual maximum and minimum temperatures were developed as a function of altitude, latitude, and longitude for the "Pólo Turístico do Circuito das Frutas" region. The obtained correlation coefficients varied from 0.91 to 0.96 and 0.71 to 0.94 of the maximum and minimum air temperature, respectively. Also, maps with the spacial variability of the maximum and minimum mean monthly and annual temperatures are presented for the region.
