At A Glance

Tar

Reading the tar score Higher is cleaner. 10 means less tar reported; lower scores mean more tar or oil.Based on beach reports. Reports from the past 72 hours count, with more weight given to recent, better-supported reports. The lowest sand, water or smell score sets the overall score.A dash means unknown. No reports does not mean a clean beach.How scoring works

Surf is an unvalidated breaking-wave estimate; offshore wave height is not surf height. Each height carries the period of its own source: the Surf period comes from the sample the breaking estimate was computed from, the Offshore swell period from the wave model's own row. A period shown as – is one the source did not supply. No calibrated accuracy percentage is available. Wind is the atmospheric weather forecast, not wind-wave direction.

Estimated Breaking Face, Not Offshore Wave Height

No exact beach-reported face heights in the latest reports. Hovering an estimated-face point states the period of the sample that height was modeled from. The report form does not collect a wave period, so a crowd report's height says the period was not reported rather than borrowing the forecast's.

Primary model

Multi-buoy surf model, this beach's estimate

What the multi-buoy model is The surf figure on this page is computed from several buoys' directional wave spectra, with the land between each buoy and this beach screened out. It is a model ESTIMATE and it has not been calibrated against measured breaking surf, so no accuracy figure is claimed for it. The baseline beside it is the height the older exposure/CDIP tier produced at the same run, kept so the change stays auditable. A difference between the two is two models disagreeing, not either one being right.
Multi-buoy model, this beach's estimate 3.1 ft
Legacy baseline, same run 3.5 ft window-model
Difference from the baseline -0.4 ft this beach's estimate minus the older tier at that run

Stations used: Topanga Nearshore, Santa Monica Bay, Santa Monica Basin, San Pedro, Long Beach Channel, San Pedro South, Santa Cruz Basin, East Santa Barbara

  • exposure: curated arcs at every frequency; bins at or above 0.09 Hz are UNSCREENED (no coastline geometry supplied)

  8. IncidentNews Satellite Imagery Anomaly; off Malibu, CA 2.6 km away

    The morning of 06-AUG-2024, NOAA NESDIS issued a Marine Pollution Surveillance Report (MPSR) for possible oil identified by satellite imagery just offshore of Malibu, CA. Imagery was collected at 06-AUG 0150 UTC (05-AUG 1850 hrs Pacific) from a Sentinel 1A (synthetic aperture radar) satellite. USCG and Malibu lifeguards investigated. USCG helicopter overflight was delayed due to marine layer conditions. Vessels on water observed no oil, but helo observed some material in the water. Upon closer inspection by surface vessels, no oil was observed and all units returned to base.
