Dengue haemorrhagic fever (DHF) is an acute endemic disease and lead to epidemic outbreak periodically. DHF cases reported since 1968 in Indonesia and continues to increase rapidly showing the existence of outbreak which tend to occur every year. The increasing cases of dengue fever in Indonesia during the rainy season may have been caused by the increasing of earth's temperature. Changes in temperature and rainfall can stimulate mosquitoes to expand their habitat. This causes mosquitoes breed and spread more quickly. The incidence of DI-IF in 2007 was 157.9 per 100.000 population, rose to 153.5 per 100.000 population in 2008; 136.2 per 100.000 population in 2009: 29.5 per 100.000 population in 2010 and rose again to 59.43 per 100.000 population in 2011. The purpose of this study was to find the occurrence of DHF based on rainfall patterns, temperature, rainy day and humidity in Bat= city of Kepulauan Riau Province. This study is a retrospective study. Rainfall data was collected from Bureau of Meteorology, Climatology and Geophysics while the incidence of DHF based on reports from the Health Department during the last 9 years since 2001-2009. The data was analyzed univariate and bivariate by utilized Kendall Concordansi Cooficient. The results of analysis for Batam show that pattern of higher rainfall occurred in 2001, after which a decline despite a slight increase each year. The pattern of incidence of dengue has increased in 2001- 2009. Correlation of the rainfall, temperatue and DHF cases was occured during the study with r value is 0.31 for rainfall and 0.26 for temperature. There was no correlation of rainy day and humidity with DHF cases.
