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 9.8 ft @ 12.5s energy period 11.3 s from WNW 290°

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 5.4 ft @ 15.4s energy period 12.0 s from W 265°

Partitions combine to 5.4 ft significant height , against 5.3 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 9.2 ft
Legacy baseline, same run 7.9 ft window-model
Difference from the baseline +1.3 ft this beach's estimate minus the older tier at that run

Stations used: Bodega Bay, Point Reyes, San Francisco, Pt Arena

  • exposure: curated arcs at every frequency; bins at or above 0.09 Hz are UNSCREENED (no coastline geometry supplied)
  • 46237: nearshore-transformed -- nearshore at this period (h/L0 0.07): a transformed nearshore record, not offshore forcing

  2. IncidentNews Vessel Adrift; Dillon Beach, California 9.6 km away

    The OR&R Hazmat Duty Officer received a call from the answering service on the morning of December 15, 2025. The NOAA Scientific Support Coordinator (SSC) followed up with a U.S. Coast Guard (USCG) contact and was notified that an18-foot fiberglass vessel was adrift near Dillon Beach, last spotted Saturday, December 13, and was involved in a search and rescue operation. No support was requested. An estimated 3 gallons of gas was still on board.

  3. IncidentNews Grounded Fishing Vessel Aleutian Storm; Bodega Bay, CA 3.1 km away

    On February 10, 2024, the USCG Sector San Francisco contacted their NOAA SSC to report the grounding of the F/V ALEUTIAN STORM near Salmon Creek, just north of Bodega Bay, CA. The vessel was on the beach amidst the surf. No pollution was observed, but the vessel reportedly had 1,500 gallons of diesel on board. USCG sought oil fate & transport info in the event of a release prior to or during vessel salvage operations.

  5. IncidentNews F/V BARBARA MARIA spill; Spud Point Marina, Bodega Bay, CA 2.1 km away

    Late morning on 16-SEP-2021, staff from the Greater Farallones National Marine Sanctuary contacted their NOAA SSC to request a trajectory for a reported diesel spill in Bodega Harbor, CA. Further information obtained from USCG Sector San Francisco indicated that roughly 200-300 gallons of diesel fuel may have discharged from the F/V BARBARA MARIA during a tank-to-tank transfer late in the evening of 15-SEP-2021. Winds have been light & variable since early in the spill and USCG Sector San Francisco observed scattered sheen in other areas of Bodega Harbor. Oil fate & transport info was requested.

  6. IncidentNews P/C JI-ME II sunk; Inverness, CA 94937, USA 13.5 km away

    On the afternoon of 03-AUG-2021, USCG Sector San Francisco contacted their NOAA SSC regarding a sunken 30' fiberglass pleasure craft JI-ME II. The vessel is reportedly carrying 200 gallons of diesel on board and was observed sheening near the surf zone, just north of Driftwood Beach on Tomales Point. USCG requested information on the likely fate of the diesel.

  7. IncidentNews Tug Boat and Towed Fishing Vessel Adrift, Bodega Bay, CA 5.6 km away

    In the evening of 05-MAR-2021, USCG Sector San Francisco contacted their NOAA SSC regarding a tug boat & towed fishing vessel drifting towards shore off Bodega Bay, CA. During transit from WA State, the Tug HUNTER was towing the F/V AMERICAN CHALLENGER when there was a loss of propulsion and both vessels started drifting to the NNE. At the time of the report, the Tug HUNTER had deployed their anchor, but it had not yet caught bottom. USCG indicated that the primary pollution concern was from the Tug HUNTER, reportedly carrying 26,000 gallons diesel and 1,100 gallons. USCG requested a hypothetical trajectory estimate in the event of a grounding/spill to inform field investigations the following morning. The tug was able to anchor and was later towed to port but the fishing vessel grounded on rocks in a remote area south of Estero de San Antonio. A response effort is underway.

  8. IncidentNews GFNMS whale carcass; Salmon Creek Beach, California 5.1 km away

    On the morning of 30-JUL-2020, the Greater Farallones National Marine Sanctuary (GFNMS) contacted their NOAA SSC to request a hindcast trajectory for a whale carcass. The GFNMS is working with the Marine Mammal Stranding Network to determine if a whale carcass found near Bodega, CA on 23-JUN-2020, might be the same carcass observed near Point Reyes on 14-JUN-2020.

  10. IncidentNews F/V Sea Biscuit; Near Bodega Bay, CA 2.3 km away

    At 1045hrs (local time), CA’s Office of Spill Prevention & Response (OSPR) contacted their NOAA SSC to request a trajectory estimate for the F/V SEA BISCUIT, which beached late last night in the surf near Bodega Bay, CA. The vessel has 150 gallons of diesel on board and a rainbow sheen was observed nearby sometime this morning. The State is considering a temporary closure of some local fisheries in the vicinity as a result of the spill and have requested a trajectory estimate on which to base their closure boundary.

  11. IncidentNews Tarballs 98; Bodega Bay, CA 2.9 km away

    At about 1450, Saturday, 17 January, MSO San Francisco was notified of stranding tarballs and oiled wildlife on the beaches of Drakes Estero. Teams found tarballs, oiled vegetation and scattered tar patties along the beach at the water line. Wildlife teams began collecting oiled live and dead birds. A Unified Command was established and the Coast Guard hired cleanup contractors to remove the oiled debris. To date, about 120 lbs of tar and solid waste has been collected. Several overflights have been conducted and no floating oil has been found. Assessments of other Point Reyes area beaches have been made and no new oiling was found. As of yesterday, a total of 64 oiled birds have been collected for cleaning and 115 have been found dead. Rescue efforts will continue as impacts to wildlife remain and further assessment are planned. USCG district 11.
