Dengue remains a major vector-borne disease and a persistent public health problem in Indonesia. West Java is one of the provinces with a high dengue burden, while climatic variability may shape ecological conditions that support Aedes mosquito survival and dengue transmission. This study aimed to describe the spatial distribution of dengue incidence according to rainfall, air temperature, relative humidity, and wind speed in West Java from 2019 to 2023. A descriptive ecological time-series study was conducted using aggregated dengue data from 27 districts/cities and climate data from four meteorological stations managed by the Indonesian Agency for Meteorology, Climatology and Geophysics. Dengue incidence rates were mapped at the district/city level, while climate variables were interpolated using the Inverse Distance Weighting method in QGIS and classified with natural breaks. Spatial overlay was used to identify visual coincidence between dengue incidence and climate variability. Dengue incidence showed an uneven spatial pattern, with higher incidence repeatedly observed in Bandung Raya, parts of Bogor, Sumedang, and Tasikmalaya. Areas with higher dengue incidence often coincided with moderate-to-high rainfall, warm temperatures, high relative humidity, and relatively low wind speed. These findings suggest that integrating climate information into routine dengue surveillance may support risk stratification and early warning in West Java. Further analytical studies are needed to quantify the association between climate variability and dengue incidence.
