                         statistics were used to define the main features of the rainy 
                         season in S{\~a}o Paulo, Brazil, including their start, end, and 
                         duration, in addition to the distribution of quantities of rain 
                         and risk of dry spells. The analysis was performed from daily 
                         rainfall records in Piracicaba, located inside the State, in the 
                         period of 1917 to 2014. The obtained start dates were: September 
                         20 for the early potential and October 12 for effective one, which 
                         is the start of rains conditional to a non-occurrence of one 
                         consecutive dry spell. The end of rains was defined as being the 
                         day March 10, and your effective average duration was 152 days. 
                         There was a significant inverse linear dependence (r = -0.74) 
                         between the start and the duration. Precipitation expected by 
                         pentads in the various levels of probability were obtained through 
                         adjustments to gamma distributions. Are also presented findings on 
                         the risk of 5 to 30 days dry spells in the following 30 days. 
                         Finally, the relative frequencies of rainy and dry events in their 
                         different intensities from light to extremes, on the scales of 1 
                         to 12 months, are computed using the SPI. It is concluded that 
                         these results have great practical interest for design and 
                         operation of water resources systems for hydro and 
                         agrometeorological purposes.",
