Historical Weather Maps on the Internet Archive

Before satellite imagery and computer models, weather forecasting relied on networks of ground observations plotted by hand onto maps. These historical weather maps document both the state of the atmosphere and the state of meteorological science at each moment in time.

The Internet Archive hosts weather maps from government archives and institutional collections, spanning the era from early telegraphic weather services through the mid-20th century. The cartographic conventions, data visualization techniques, and artistic quality of these maps evolved dramatically over this period.

For climate researchers, historical weather maps provide data that supplements instrumental records. For data visualization designers, they are a rich source of techniques for representing complex, multivariable spatial data — problems that remain challenging today.
