SURGEDAT archives historical storm surge data. In fact, SURGEDAT is the world’s most comprehensive storm surge database, with more than 700 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: Global Peak Surge Map, Interactive Surge Maps, and Live/Archived Storm Surge Updates. Each tool is slightly different in the functionality and geographic area of coverage.
