SURGEDAT archives historical storm surge data. In fact, SURGEDAT is the world’s most comprehensive storm surge database, with more than 560 global peak storm surges since 1880. More than 300 of these events occurred in the United States. The SURGEDAT website hosts three different storm surge tools: The Global Peak Surge Map, Historical Surge/ Hurricane Maps, and Interactive Surge Maps. Each tool is slightly different in the functionality and geographic area of coverage.
Global Peak Surge Map
This tool provides an interactive global peak storm surge map. Circles on this map represent unique storm surge events. Larger, darker circles represent higher magnitude events. When users click on a surge observation, a pop-up box indicates the storm name and year, as well as the location and height of peak storm surge.
Historical Surge/ Hurricane Map
This tool provides maps that plot the location and height of historical storm surge and storm tide observations, as well as the track and intensity of the hurricane that generated the high-water marks. Maps are provided for 20 events, including the top 10 magnitude storm surges that impacted each of the U.S. Gulf and Atlantic Coasts.
Interactive Surge Maps
This tool enables users to map all storm surge observations for hurricanes and tropical storms that have impacted the U.S. Atlantic and Gulf Coasts. A map of storm surge observations is plotted when users select the name and year of a storm. This tool also provides an interactive map that lists information related to the location of an observation, the storm surge and/or storm tide height, as well as the datum and type of observation.
