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

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 5.7 ft @ 13.3s energy period 11.8 s from W 265°

Partitions combine to 5.7 ft significant height , against 5.7 ft measured at the station. Spectrum sampled Oct 21, 12:00 AM.

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 9.0 ft
Legacy baseline, same run 6.5 ft window-model
Difference from the baseline +2.5 ft this beach's estimate minus the older tier at that run

  3. IncidentNews Stranded Vessel in San Francisco Bay; Belvedere Tiburon, California 17 km away

    The U.S. Coast Guard (USCG) notified the NOAA Scientific Support Coordinator (SSC) of a 31-foot pleasure craft stranded on a riprap shoreline at Point Chauncey in San Francisco Bay. The USCG is concerned the vessel may break up before it can be salvaged. The owner reported there were approximately 20 gallons of fuel on board. Fuel capacity is 80 gallons. The type of fuel is suspected to be diesel, but that has not been confirmed. No additional support requested at this time.

    On February 2, 2026, the U.S. Coast Guard (USCG) contacted the NOAA Scientific Support Coordinator (SSC) regarding a red sheen coming from five bait pens moored off the Hyde St. Pier in San Francisco Bay, California. The material resembled red dye diesel, but had no discernable odor and appeared to be coming from the bait pens. The bait fish appeared to be live, active, and unaffected. A biological source is suspected.

  13. IncidentNews Possible Pollutant Report; off Stinson Beach, California 2.1 km away

    Mid-day on March 15, 2025, USCG Sector San Francisco's Incident Management Division contacted their NOAA SSC regarding a possible oil sighting off of Stinson Beach, California. Initial reports from Stinson Beach Fire Department indicated “black blotches breaking up in the water.” The fire department was not able to get within 500 yards of the material, but did not smell any petroleum product. They chose to make a report to the National Response Center (NRC) in an abundance of caution. USCG then requested input on a possible pollution event. Photos were provided. Further investigation revealed that the source was biogenic—masses of small jellyfish-like creatures, Vellela velella, commonly known as “by-the-wind” sailors—and not a pollutant. The USCG stood down operations on the case, with no further requests for OR&R support.

  18. IncidentNews Chevron Pipeline Spill; Long Wharf, Richmond, CA 21.3 km away

    At roughly 1500 hrs on 09-FEB-2021, there was a reported release of “intermediate bunker fuel” from a pipeline along the Richmond Long Wharf at the Chevron Refinery. The NRC report (No. 1297669) indicated an estimated release rate of 5 gallons/minute. USCG Sector San Francisco contacted their NOAA SSC to request trajectory support while Sector pollution response personnel are en route and a USCG overflight is being requested. In the meantime, local news helicopter video footage at roughly 1700 hrs appeared to show no active release, but did show light winds and oil & sheen close to shore just south of the wharf.

The second report from the Tug Arthur Brusco was of a N/S oriented sheen approximately 12 NM from the earlier report and within the vessel Traffic Separation Scheme outside the entrance to San Francisco Bay. USCG requested a hindcast trajectory to determine if the two sheen reports might be related and to narrow down the potential source(s).

  26. IncidentNews M/V Fernstream wreck project; San Francisco Bay, CA 18.3 km away

    On the morning of December 11, 1952, the diesel-powered general cargo ship M/V FERNSTREAM sank approximately 1 NM East of the Gold Gate Bridge after being involved in a collision with the SS HAWAIIAN RANCHER. At the time, she was headed to Manila, Philippines and loaded with 3,000 tons of soybeans, general cargo and an estimated 12,500-19,000 bbls of diesel fuel. The FERNSTREAM is one of four potentially polluting shipwrecks described in NOAA’s RULET (Remediation of Underwater Legacy Environmental Threats) risk assessments for the waters off California (USCG District 11). Because it is not yet clear whether substantial amounts of the ship’s bunkers may remain aboard the FERNSTREAM, a USCG Sector San Francisco-led Taskforce is considering the potential pollution risks of the ship based on initially available data and subsequent investigative efforts. This Hotline has been created primarily as an archive for NOAA’s support of the Taskforce activities.
