SURGEDAT is the world’s most comprehensive archive of maximum storm surge data. This worldwide dataset and map identifies the peak storm surge location and height of tropical cyclone-generated storm surges since 1880.

This project originated with a study of storm surge activity along the U.S. Gulf Coast. The NOAA-funded Southern Climate Impact Planning Program (SCIPP) utilized 59 sources of data, including 26 Federal government sources, 17 books, academic journal articles and online publications, and more than 3,000 pages of historical newspaper, to identify more than 200 surges along the U.S. Gulf Coast. This project has now expanded, incorporating hundreds of sources from all over the world to generate a global dataset and map.

The SURGEDAT storm-by-storm information files, located to the right of the map, provide the metadata that was used to create this dataset. These metadata files are in development, but currently provide information for the Western North Pacific (WNP), Australia, New Zealand and Oceania (ANO), Northern Indian Ocean (NIO), Southern Indian Ocean (SIO), Western North Atlantic U.S. Gulf of Mexico (WNA_US_GOM) and Western North Atlantic Region (WNA_Region).

As of April 2011, SURGEDAT has identified 440 surges and mapped 411 surges. The following table provides a basin-by-basin list of surges in the dataset:

Ocean Basin	Identified	Mappped
Australia, New Zealand, Oceania	80	80
Western North Pacific (China, Japan, S. Korea)	66	37
Northern Indian Ocean (Bang, Ind, Myan, Pak)	42	42
Southern Indian Ocean	1	1
Western North Atlantic	250	250
Eastern North Pacific (Hawaii)	1	1
Total:	440	411
