Summary:The present work objectified to detect tendencies of long period in the annual averages of the air temperature. We analyzed minimum, mean, and maximum temperature, absolute minimum, and absolute maximum. Twenty-four meteorological stations on the Northern Northeast (Ceará, Rio Grande do Norte, Paraíba and Pernambuco) were used. We used the historical series from 1961 to 1990. To identify the tendencies, we used the analysis of lineal regression analysis. The Student's t-test was used to verify the statistical of the coefficients of lineal regression. We observed an increase of the minimum, mean, maximum temperature, and absolute minimum. The absolute maximum temperature didn't present significant tendencies of increase nor of decrease. We conclude that has had a decrease of the annual thermal amplitude of the temperature on the Northern Northeast, mainly, due to the increase of the night temperature.
