Swell compass
A real compass dial marks the swell's direction. Turn your phone and line up with where it's coming from.
Capture & history
Save a reading, name the session, and build your own trail of swells, with pinned all-time benchmark, Hurricane Marie (2014) for context.

Star the reading you'd want again. When the buoy reading matches, the current 4-square glows amber and shows a star.
Custom maps

What it is.
A tool for building your own surf science skills over time.
It is not a forecast, an alert system, or a safety tool.
Public buoy and swell-station feeds from CDIP (Scripps) and NOAA/NDBC, across 10 stations: the SoCal core plus Pacific reference buoys.
No go-now calls. No pretending to know your break better than you do.
Use the data, watch the water, and apply your own judgment.
