Around 404 million students were affected by school closures due to extreme weather events between January 2022 and June 2024. This is shown in a new report by the World Bank (download). The report shows that at least 81 countries had to cancel attendance classes due to floods, heatwaves, storms or other severe weather conditions. Low-income countries were hit particularly hard. On average, they lost 18 days of classes per year. In Pakistan, the figure was as high as 97 days in the one-and-a-half years examined – almost half of a typical school year. On the other hand, high-income countries only lost an average of 2.4 days of school per year.
