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.

Significant wave height is the total measured sea state at this mooring, not the height breaking at this beach. The modeled breaking estimate is on the Surf tab.

Partitions, computed here Where these partitions come from Tarline splits this station's own directional wave spectrum into a swell part and a wind sea part. The split is this site's computation, not a provider product, and it is deliberately conservative: two parts, not a list of named swell trains. Variances add and heights do not, so the combined figure below is 4 times the square root of the total variance rather than a sum of the partition heights.
  • Swell 3.1 ft @ 14.3s energy period 10.7 s from SW 226°

Partitions combine to 3.1 ft significant height , against 3.1 ft measured at the station. Spectrum sampled Oct 20, 11:00 PM.

    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. 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.

Significant wave height is the total measured sea state at this mooring, not the height breaking at this beach. The modeled breaking estimate is on the Surf tab.

Partitions, computed here Where these partitions come from Tarline splits this station's own directional wave spectrum into a swell part and a wind sea part. The split is this site's computation, not a provider product, and it is deliberately conservative: two parts, not a list of named swell trains. Variances add and heights do not, so the combined figure below is 4 times the square root of the total variance rather than a sum of the partition heights.
  • Swell 4.2 ft @ 14.3s energy period 12.2 s from SW 215°

Partitions combine to 4.2 ft significant height , against 4.2 ft measured at the station. Spectrum sampled Oct 20, 11:00 PM.

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 2.9 ft
Legacy baseline, same run 5.4 ft mop
Difference from the baseline -2.5 ft this beach's estimate minus the older tier at that run

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

  • exposure: curated arcs at every frequency, plus a known-land screen on bins at or above 0.09 Hz

Computed Oct 20, 11:33 PM · buoy-spectrum-shadow-3

Panel assembled Wed, Oct 21, 2026, 12:03 AM PDT. That is not how fresh any station reading is.

  4. IncidentNews Satellite Imagery Anomaly; off Malibu, CA 23.5 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.

  5. IncidentNews Tank Truck Jet Fuel Spill; Point Mugu, CA 17.1 km away

    On Friday morning, November 18, 2016, a mobile tank truck overturned near the entrance to the Point Mugu Naval Air Station and released approximately 1,500 gallons of JP8 jet fuel onto the pavement and into a nearby creek.

  6. IncidentNews Re-fueling plane crash; Point Mugu NAS, CA 21.3 km away

    At approximately 1700hrs on 18MAY2011 a Boeing 707 military refueling airplane crashed at the end of the runway at Naval Air Station Point Mugu. All crewmembers survived and the aircraft burned for a number of hours. Initial reports indicated that none of the approx 25,000 gallons of JP-8 jet fuel on-board had reached the Ocean. The next morning it became apparent that some of the JP-8 had entered the marsh area adjacent to the crash site and at 0830hrs on 19MAY2011 product was observed in the tidal channel under L Avenue (approx 1/3 mile from crash site). Navy Region Southwest and USCG MSD Santa Barbara contacted the NOAA SSC to request information on oil persistence in the marsh complex and trajectory support.

    On January 4, 2006, the F/V Buccaneer sank in 1200 feet of water 2.5 miles off Point Mugu, CA, near Port Hueneme, CA. The 68-foot steel-hulled squid fishing vessel was carrying approximately 1000 gallons of diesel. Sheening was observed when the vessel sank but currently is no visible sheen.
