Climatic variables such as precipitation, relative humidity and temperature, can affect human health directly and indirectly because the human body is in permanent contact with the atmospheric environment. Diseases of the circulatory system (DCS) represent an important public health problem in Brazil, as they are the main cause of mortality and are a major cause of hospitalization. Given this context, this study aims to analyse the degree of relationship between hospitalizations for DCS and climatic factors in the city of Campina Grande-PB. The current study is an ecological survey of time series for the period between 1998 and 2013. Initially, hospitalizations for DCSwere analyzed, and then these hospitalizations were associated with average values ​​of the climatic variables measured in the municipality. The statistical methods used were the Shapiro-Wilk test, Pearson's correlation and multiple linear regression. This study found a correlation between climatic elements and hospitalizations for hypertensive diseases. The correlation verified with the climatic elements indicates that the hospitalizations due to DCS present moderate to strong correlations. The variables average temperature and relative humidity are the ones that most influence the behaviour of these diseases. The climatic elements together explain 43% of hospitalizations for hypertensive diseases, 36% of hospitalizations for ischemic heart diseases and 34% of hospitalizations for heart failure.
