Great Lakes Climatologies

The description of the typical climate of a particular place, its climatology, is based on observations collected by local weather stations or buoys over many years. In partnership with the Office of the State Climatologist, GLISA developed summaries of this information for select sites (stations), multi-county areas (climate divisions), and each Great Lake across the 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. These were formerly GLISA’s Station Climatologies and Climate Divisions.
