Current readings
Height, period, direction, and sea surface temp, straight from the source, with yesterday beside them and color-coded change.
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. Hold a row in Recent Data to save a reading from earlier in the day.
Star a reading
Star the reading you'd want again. When the buoy reading matches, the current 4-square glows amber and shows a star.
Swells and average period
Two switches in Settings, off until you want them. Swells lists up to three swells behind one reading, each with height, period and direction. Avg Period adds the average of every wave in the spectrum.
Custom maps
Every buoy on its own coastline map, relative to shore.
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. 109 stations across the North Pacific; ten SoCal and reference buoys to start, then add your own.
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.
