The climate change, in different spatial-temporal scales, consolidates several climatology researches in order to comprehend the climatologic dynamics, as well as climate attributes in such process. Rain represents complexity on the atmospheric dynamic understanding, once it presents its genesis based on different atmospheric processes. With that, the following study comprehends the rain behavior in the region of São Carlos/SP according to daily rain data in the climatological stations in this region from the historical series from 1993 to 2014. In this study, the bibliographic revision was performed concerning the rain genesis for Brazil and for the state of São Paulo, apart from the determination of indices proposed by Zhang and Yang (2004), RX 1 day (maximum accumulated in a single day), SDII (single strength index), DCU (consecutive wet days), DCS (consecutive dry days), PRCPTOT (total precipitation in wet days) and index calculus through the software R with the script Rclimdex 1.1. The calculated data present a great floating along the historical series 1993-2014 for all the admitted index, which sets the presence of years below and above the average for each index and point to regional climate dynamics with daily values of rainfall by the regional planning. Keywords: Indices, Statistical Climatology, Rain, RClimdex.
