How to read this page
How to read wave height
The 2.5 m significant height is the average of the tallest third of waves at the buoy, with a 8 s period; occasional waves run close to double that.
What the number doesn’t tell you
The buoy measures a single point; the beach itself can have quite different wave height and shape, from bathymetry and local wind.
Words on this page
Significant wave height
The average of the highest third of waves measured by a buoy over a time window, not the single tallest wave seen. In practice, occasional individual waves reach nearly double that value, which is why surfers and sailors treat significant height as a floor, not a ceiling.
Standard definition by NOAA NDBC — National Data Buoy Center · Significant wave height
Preliminary data
A measurement published as soon as it is collected, before the agency’s final review. It can be corrected or withdrawn: earthquake magnitudes shift in the first hours, air-quality readings are revised weeks later. Use it to plan your day, not for regulatory or legal purposes.

How to read these numbers
Buoys are listed from the largest wave height down. The time of each reading is in UTC, as the source publishes it.
Frequently asked questions
- How is the surf in US Northeast right now?
- The table carries the significant height and period for each buoy in the area, with the observation time.
- Why does a buoy show no wave height?
- Some buoys only measure wind, pressure and temperature. We list only those reporting wave height.
