Schools in Noida and Delhi, catering to students from nursery to Class 8, will remain closed until January 15 due to severe cold wave and dense fog conditions. The district administration and Directorate of Education cited health risks and low visibility as reasons for extending winter vacations. While older students (Classes 9-12) may have online classes or adjusted timings, younger students are advised to stay home. Authorities have warned of strict action against schools violating the closure order, emphasizing student safety as the top priority.
