Significant wave height here is the total measured sea state at this mooring. It is not the height breaking at any beach; each beach page models that separately from its own exposure.

    Latest report received from this physical station; individual fields can have older observation times. This is the recorded start of the most recent successful live poll across this station's products, not response completion or proof that every field refreshed.

    Successful fetch
    recorded time for the last accepted fetch; not proof the value changed (see source timing details below)

    One instrument's own reading of open water, selected independently of the water temperature station. The observation time is the oldest of the wave fields shown, so it can overstate a single field's age but never understate it. Read through CDIP, Scripps Institution of Oceanography as 284. The fetch timestamp records the start of a successful poll of this field's provider and product, not response completion or the age of the reading.

    Wave systems are partitioned from this measured spectrum. The fetch timestamp records the start of a successful poll of this provider's spectral product, not response completion. Spectra are retained for 72 hours.

All times are Pacific. An upstream issue time is shown only when recorded. A feed response time is not the provider's model initialization or publication time. Unlisted timestamps were not recorded or do not apply.

Partitions · computed here from this station's spectrum
  • Swell 3.9 ft @ 15.4s energy period 12.0 s · from SW 220°

A conservative swell and wind sea split of this station's own directional spectrum, computed by Tarline rather than published by the provider. Variances add and heights do not, so the combined figure is 4 times the square root of the total variance. Partitions combine to 3.9 ft significant height , against 3.9 ft measured at the station. Spectrum sampled Oct 21, 12:30 AM.

Station Observations — Capistrano Beach NearshoreWhat this station measuresThese are instrument measurements at this station, which may be an offshore buoy or a fixed coastal platform. Significant wave height is not a beach-specific breaking height. Each beach page states its own modeled breaking height separately.NDBC 46285 · CDIP 284 · raw observations · past 168 h
