Vector-borne diseases (VBDs) in Eastern Uttar Pradesh display pronounced seasonal and spatial variation shaped by the interaction of climatic and ecological conditions. This paper examines temperature, rainfall and relative humidity as major climatic determinants of malaria, dengue and Japanese encephalitis (JE), using climatic normals for 1991–2020 and disease surveillance data from NCVBDC. The analysis combines monthly and district-level climatic data, disease seasonality, climate–disease correlations and lag relationships. Mean monthly temperature rises from 15.8°C in January to 32.5°C in May, while rainfall is strongly concentrated from June to September and relative humidity exceeds 80% during July–September. Disease occurrence follows this climatic rhythm but with disease-specific timing: malaria and JE intensify during the monsoon, whereas dengue peaks later in the post-monsoon period. The correlation matrix reports strong positive associations of rainfall with malaria (r=0.888) and JE (r=0.970), and positive associations of humidity with malaria (r=0.749), dengue (r=0.672) and JE (r=0.704). Lag analysis further indicates that rainfall-related disease peaks occur approximately one to two months after climatic exposure. These findings show that climate operates through temporally delayed and disease-specific pathways rather than as an instantaneous determinant. The paper argues for climate-informed surveillance, pre-monsoon preparedness and geographically differentiated vector-control strategies in Eastern Uttar Pradesh.
