Visit the world's storm surge data center, providing information on over 700 global tropical surge events and more than 8,000 high water marks from surges along the U.S. Gulf and Atlantic Coasts.

This website has archived the location and height of more than 700 tropical surge events around the world since 1880 and identified more than 8,000 unique high water marks from tropical surges along the U.S. Gulf and Atlantic Coasts.

These data were mostly built from scientific sources, including government reports, historic maps, academic papers, and books, but anecdotal sources—such as thousands of pages of newspapers—provide data for smaller-magnitude storm surges in the earlier part of the record.

This storm surge history is valuable for emergency management personnel, coastal scientists, storm surge modelers, forecasters, planners, insurance professionals, and coastal stakeholders.

Resources include data downloadable in CSV format, surge maps that map and track the course of past storms, and historic maps of the top 10 Gulf Coast storm surges.

The low-effort tool is intended for beginner-level users.
