The objective of this study was to estimate the threshold temperatures and the thermal requirement of mango, in the northeast of the state of Para. One experiment was carried out in a mango orchard of 25 hectare during the 2010/2011 and 2011/2012 season in which the phenological and meteorological conditions were daily monitored from flowering to harvest. Both mango seasons were submitted to different meteorological conditions, and therefore, both the duration of the reproductive stage and the mean thermal requirement were significantly different. The thresholds temperatures (lower and higher) of the mango were 13 °C and 32 °C, respectively, the thermal requirement found for the mango orchard reach to the harvest stage was 1,024.23 °C day-1 and 1,157.99 °C day-1, and the mean duration of the mango season was 110 and 112 days.
