Annual High Tide Flooding Outlook

Annual Outlooks show the number of high tide flooding days predicted for the coming meteorological year (May to April). The site also gives users a way to visualize observed and projected high tide flooding at National Ocean Service water level stations. 

Data is supplemented with decadal projections for the year 2050, sea level rise scenarios, and high tide flood exposure maps to support long-term coastal planning. Summaries are provided for each region to account for geographical differences at the coast, and are accompanied by regional graphics to demonstrate potential high tide flooding impacts.
