How have weather fluctuations affected infant mortality in Africa over the last half century? To answer, we combine individual level data, obtained from retrospective fertility surveys (DHS) for nearly a million births in 28 African countries, with data for weather outcomes, obtained from re-analysis with climate models (ERA-40). We find robust statistical evidence of quantitatively significant effects via malaria and malnutrition. Infants in areas with epidemic malaria that experience worse malarious conditions during the time in utero than the site-specific seasonal means face a higher risk of death, especially when malaria shocks hit low-exposure areas. Infants in arid areas who experience droughts when in utero face a higher risk of death, especially if born in the so-called hungry season. We also uncover heterogeneities in the infant mortality effects of growing season rainfall and drought shocks, depending on household occupation or education. Based on the estimates, the paper estimates the number of infant deaths due to extreme weather events and the total number of infant deaths due to maternal malaria in epidemic areas.
