California buoy cluster
California Central Coast surf buoys
California Central Coast has a distinct mix of northwest, west and south-swell exposure. This page limits comparisons to a useful coastal window instead of mixing the full California coastline.
Read exposure before height
Start with a recent physical buoy, then compare period and direction with the orientation of the coast.
Headlands, islands and curved bays create shadow zones; a strong offshore reading does not guarantee the same size at every beach.

Latest regional observation:
History is enabled gradually when reusable, correctly identified observations are available. Models and references without a stored series keep their own page, but do not show historical charts.
Comparison: physical station and marine model
These sources answer different questions. The physical station represents an instrument; the model provides an estimate for a coastal grid point.

No numeric difference is calculated when either source has no reading.
Buoy and history FAQs
What buoy information is available for California Central Coast surf buoys?
The published catalog includes 6 physical or reference stations and 1 model point for this region. Each source identifies its provider, location, data type and history status so observations are not mixed with estimates.
Why do some buoys have no historical charts?
Charts appear only when SwellOracle has a stored series of reusable, correctly identified observations. A station can keep its information page even when there is not yet a sufficient series for a chart.
What is the difference between a physical buoy and a marine model?
A physical buoy or station represents instrument measurements. A marine model estimates conditions at a grid point. Use observations as local confirmation and models as spatial context rather than treating them as equivalent sources.
How should swell height, period and direction be interpreted?
Read all three variables together: height describes the size of the signal, period helps explain its energy and direction shows where it comes from. Coastline shape, depth and local exposure can change what reaches the beach.
Practical takeaway
Use California Central Coast buoys as observed confirmation and models only as clearly labelled regional context.
