Welcome to our Syracuse Weather Dashboard.
This offers a comprehensive, data-driven look at the key weather variables, such as temperature, snowfall, and storm frequency, that define the academic experience at Syracuse.
This dashboard is to provide current and prospective students, faculty, and local residents with a clear, historical understanding of Syracuse’s renowned winter climate. By analyzing decades of data from the National Centers for Environmental Information (NCEI) and the National Weather Service, we aim to allow users to move beyond anecdotes and utilize verifiable data to prepare for the academic year and the inevitable snowfall.
