Great Lakes Station Climatologies

The description of the typical climate of a particular place, its climatology, is based on observations collected by local weather stations over many years. In partnership with the Office of the State Climatologist, GLISA developed summaries of this information for selected sites across the Great Lakes region. Each summary includes an overview of the climate along with relevant data and graphs. These summaries can help guide local-level climate adaptation decisions.
