This study examined drought-temperature influences on malaria incidence in Saki and Sepeteri, Oyo State, Southwest Nigeria, using monthly climate and health data from 2013 to 2023. Drought conditions were characterized using standardized precipitation indices (SPI-1, SPI-3, and SPI-12), and associations with malaria were analyzed using regression models accounting for seasonality and temporal lags. Malaria transmission was strongly seasonal, peaking during July-November, with mean monthly cases reaching 1,134 in Saki and 869 in Sepeteri.
