Notice: We are experiencing a wide spread communication outage affecting the availability of water level and meteorological data for some of our stations, as well as several critical bridge clearance measurements. We are diligently working to resolve this data outage. Please direct all questions to tide.predictions@noaa.gov or call (301) 713-2815.

Global Regional Trends Comparison (4 Main Regions, various subregions)

The graphs compare the 95% confidence intervals of relative sea level trends. Trends with the narrowest confidence intervals are based on the longest data sets. Trends with the widest confidence intervals are based on only 30-40 years of data. The graphs give an indication of the differing rates of vertical land motion, given that the absolute global sea level rise is believed to be 1.7-1.8 millimeters/year. The calculated trends for all CO-OPS stations are available as a table in millimeters/year and in feet/century A complete table of non-CO-OPS station trends are available as a table in millimeters/year and in feet/century.
