Malaria is one of the most important tropical diseases affecting people around the world. The malaria fluctuation patterns and the influence of environmental variables on it could determine the emergence or re-emergence of the disease. To the present study it was used a temporal malaria series from 1989 until 2009 from four provinces of Argentina, Salta and Jujuy (northwestern region) and Misiones and Corrientes (northeastern region). The apparition of malaria cases in relation with climatic conditions was analysed with Random Effect Poisson Regression. This analysis takes into consideration the effect of each climatic variable on the malaria cases apparition. There were reported 12603 malaria cases, of wich 9727 were cited to Salta and 1304 to Jujuy (northwesrtern Argentina) and 1351 to Misiones and 12 to Corrientes (northeastern Argentina). It was observed marked peaks in 1990 and 1996 to the northwestern region decreaseing later until now. To northeastern, there were two important peaks in Misiones (1991 and 2007) an only one to Corrientes in 1996. Malaria cases were influenced by the mean annual temperature and by the accumulated annual rainfall. Therefore, the malaria annual incidence decrease when these variables increase. The present research results the first report to Argentina about the effect of the temperature and accumulated rainfall on the malaria dynamics allowing us to know the impact of  the enviroment  in the appearance and abundance of the disease.
