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.

Experimental

Multi-buoy surf candidate, shadow run

What a shadow candidate is A second, unvalidated surf estimate computed from several buoys' directional spectra. It runs alongside the model this page shows so the two can be compared over time. It does not set the surf figure, the forecast table or any score on this site, and no accuracy has been established for it. A difference between the two is agreement between two models, which is not the same thing as either one being right.
Candidate, shadow only 8.0 ft
Production model, same run 6.8 ft window-model
Agreement gap, not accuracy +1.2 ft candidate minus the production model at that run

    On the evening of September 22, 2026, a Hunter Hawk jet crashed into the Pacific Ocean near Morro Bay, California. The U.S. Coast Guard (USCG) contacted the NOAA Scientific Support Coordinator (SSC), requesting a trajectory analysis for 977 gallons of JP-5 (Jet Propellant-5). Additional information is unavailable at this time.

Evidently the leak started at about 1600 on 03OCT01, when the valve was ruptured by a vehicle. The MSO reported that the local fire department was responding and planned to evacuate within a 0.5 mile radius of the area at 0700 this morning to complete the response. The MSO asked the SSC to provide information on how large a footprint the gas might make, to confirm that a 0.5 mile radius was appropriate and for some information about the behavior of this compound and health and safety concerns.
