Dengue is well established from the year 2006 onwards with good abundance of vector mosquito species Aedes aegypti and Ae. albopictus in district Dehradun. The present study aimed to link meteorological variables with dengue cases in district Dehradun. During the study period (January 2012 to December 2014) the climatic variables viz., temperature, relative humidity (07:19h and 14:19h) and total rainfall were considered and analysed statistically. Dengue cases showed highest significant positive correlation with minimum temperature in 12 lag weeks i.e., 0.7195, p < 0.05. Mean maximum temperature showed positive relation in different lag weeks but none is significant. Highest Poisson-regression co-efficient was found with precipitation of 10-week lag period (b = 3.738; p < 0.01). The time series Poisson regression model demonstrated goodness of fit (R2 = 0.849) with a correlation between observed and predicted number of dengue incidence rate 84.90%, revealed that the model fitted the data reasonably well. This study suggests that antecedent climatic conditions have a differential impact on dengue over the course of year and in order to avoid camouflage of temporal variations of weather, it is also essential to interpret findings by estimating both short and long term weather variations in Dehradun city.
