In light of global climate change, the variance of rainfall is projected to increase substantially, affecting every country. In this paper, we examine how exposure to rainfall during the first 1,000 days of life influences women's long-term human capital accumulation in the context of 28 African countries. Exploiting the exogenous deviations of rainfall from the historical norms, we document a positive relationship between rainfall during the first 1,000 days and women's educational attainment. The effects mostly come from rainfall variability in agricultural season. There is also suggestive evidence that larger impacts are detected among women from low-income countries and women living in areas with poor market integration.
