In this work, it was utilized rainfall, temperature and relative humidity of the air data of Recife, Pernambuco State, to compute the temporal changes in the referred meteorological parameters since 1961 until 2000. First off all, the 40 years data were distributed in 10 years series, which were analyzed the behavior of the climatic parameters. After that, using the normalized deviations and the method of least squares for all 40 years period, the results indicated that there was a decrease of 247,0 mm in the precipitation during the last decade in Recife, event that is associated with two intense episodes of El Niño phenomenon during 1993 and 1997/1998. Concerning the air temperature, it was noted a global increase from 0,02% in the last 40 years and a monthly average decrease of the relative humidity of the air, mainly in the last decade.
