The State of Pernambuco presents in its greatest extent with a semi-arid climate, which encompasses the Sertão and Agreste Mesoregions and is characterized by long droughts, high temperatures and low rainfall. Its economy is based on the cultivation of beans, corn and beef cattle, in addition to containing one of the largest dairy basins in the state. Thus, the objective of this work is to assess the severity of drought and floods through statistical variability. The studied area was in the Southern Agreste Region and the data collections comprised the period from 2010 to 2018 on milk production at IBGE and rainfall data, at APAC. For data analysis, the Shapiro-Wilk normality test was performed. Not finding normality, thus characterizing non-parametric data, Spearman's correlation was used. The data were submitted to the statistical software R at 5% probability (P <0.05). During the studied period, there were peaks of rain in 2010, 2011 and 2017, which presented a greater number of months with high rainfall with months exceeding 500 mm monthly. On the other hand, drought in the region is a recurring phenomenon governed by climatic conditions and without human interference. In 2012, 2014 and 2016 were the ones with the highest number of months with rainfall below 300 mm monthly. It is concluded that by associating with technology and knowledge, a satisfactory milk production can be obtained in the Agreste region.
