These condition was marked by the shortening of the rainy season and the dry season was getting longer. Working area of Puskesmas Bandarharjo lies in the coast which has high air temperature. Climate change will affect to the development of microorganism that cause some diseases, one of them is diarrhea.

Statistical analysis show that there is positive correlation between rainfall variability with the incidence of diarrhea ( p = 0.0001 ; r = 0.664 ) , there is a negative correlation between variations in air temperature with the incidence of diarrhea ( p = 0.018 ; r = - 0.304 ) , there is a correlation among the positive variation of the humidity with the incidence of diarrhea ( p = 0.0001 ; r = 0.554 ) . From the results of this study concluded that there is a correlation between climatic variations in the incidence of diarrhea in Puskesmas Bandarharjo Semarang.
