| Abstract | The trends of number of rainy days; the lower and higher precipitation rates; and the precipitation totals for 3 precipitation superclasses were calculated using the MannKendall test. The data used were acquired from the rainfall stations of the north coast of São Paulo State from 1970 to 1999. According to the analysis of total precipitation, there was no significant trend during the summer. In the autumn, a significant increase in the trend was found in Maranduba and Picinguaba in Ubatuba city and Maresias in São Sebastião city for the below normal superclass, and in Caraguatatuba for the above normal superclass. In winter the trends were significantly positive in Maresias for all studied superclasses, and significantly negative in São Francisco in São Sebastião city for the above normal superclass. The significant positive trends were found in the spring and annual analysis in Picinguaba and Maresias, and in Ilhabela in the annual analysis for all studied superclasses. For the number of rainy days, Ilhabela showed a significant increase in the trend for the normal and above normal superclasses in the summer. In the autumn, there was a significant increase in the trend to the below normal superclass in Ilhabela. For the winter, a significant decrease in trends occurred in Caraguatatuba for the below normal superclass; while the significant positive in Picinguaba for the below normal superclass and in Maresias and Ilhabela for the above normal superclass were found. The significant negative trend in spring occurred only in Maranduba in Ubatuba for the below normal superclass while the increase in significant trends appeared in Ilhabela for the above normal superclass. For annual analysis, there were the decreasing significant trend in Maranduba in Ubatuba for the below normal superclass and increasing significant trend in Ilhabela for the above normal superclass and in Maresias for the normal and above normal superclasses.
