How to read a bar report

Checked September 24, 2026 against the Coast Guard, the National Weather Service and federal rules.

The Bar conditions tile repeats what the Coast Guard reports for the four regulated entrances on this coast: Crescent City Harbor, Humboldt Bay, the Noyo River at Fort Bragg and, four hundred miles south, Morro Bay. Here is what each word means, what it does not, and why one of the four has had nothing to say for over a year.

The four entrances

Each town links to its own board, where today’s report for its bar is read from the Coast Guard as it is posted, with the time it was taken.

Noyo River is the narrow entrance at Fort Bragg, watched from Coast Guard Station Noyo River. It is staffed and reporting, several times a day — which on this coast is worth saying plainly, because it is one of only three California bars the Coast Guard reports on at all, with Humboldt Bay and Morro Bay. A reading from it names the jetty tips, the middle grounds and the buoy separately, and they do not always agree.

Humboldt Bay is watched from Coast Guard Station Humboldt Bay, on the north spit overlooking the entrance. The Coast Guard calls it “one of the most treacherous bar entrances in California,” and says surf over 8 feet occurs there on about 36 days a year. It is staffed and reporting, though not always as often as the Noyo: when this guide was checked its newest report was from the morning before. The board prints that age, and past 12 hours it reads Unknown.

Crescent City Harbor is on the same weather service page, and when this guide was checked its entry read “USCG Station Temporarily Unmanned”, with a last report dated July 29, 2025 and the words “THE BAR CONDITIONS ARE NOT KNOWN. NO COAST GUARD PRESENCE IN THE LOCAL AREA.” The board shows that as Unknown, says the station is unmanned, and gives the age of that last report. It does not show it as open, and it does not show it as closed: an unmanned station is not a closed bar, and it is not a safe one. The page lists no recorded line for it, so the board prints none.

Morro Bay is the last entry on the weather service’s bar page, and the only one south of the Noyo: the harbour entrance between Morro Rock and the sand spit, watched from Coast Guard Station Morro Bay on the Embarcadero. It is staffed and reporting, several times a day, and its readings name the swell “all areas” or by part of the channel, the wind and the visibility. It is the one bar on the San Luis Obispo board; Port San Luis at Avila is an open roadstead behind a breakwater, and Cayucos, Cambria and the Pismo beaches launch off sand or a pier, so those pages carry no bar and borrow nobody else’s.

The board prints the time of every report and how old it is. A report more than 12 hours old reads as Unknown rather than as a status, because a stale bar report is the one reading on this site that could get somebody killed.

The towns with no bar at all

On the north coast, Trinidad, Shelter Cove, Orick and Petrolia have no bar report, and not because anyone forgot them. Neither Trinidad nor Shelter Cove is one of the entrances in the federal rule below, and neither appears on the weather service’s bar observations page. At Trinidad boats launch in the open bay; at Shelter Cove they launch off the beach; Orick and Petrolia face open ocean beach. The board says No bar for them and does not lend them a report from an entrance miles away. No bar is not the same as calm water: the check there is the marine forecast, VHF channel 16, and your own eyes.

Most of the California coast has no bar report at all. The weather service’s bar page ends at Morro Bay, and between the Noyo River and Morro Bay it lists nothing: no Bodega Bay, no Tomales Bay, no Pillar Point, no Santa Cruz, no Moss Landing. South of Morro Bay there is nothing either. Most harbours on that coast — Pillar Point, Monterey, Port San Luis, Santa Barbara, Ventura and Channel Islands, Marina del Rey, King Harbor, Newport, Dana Point — sit behind breakwaters or jetties, and a breakwatered harbour entrance is not a bar the Coast Guard reports on; where the entrance shoals, the harbour district posts its own notices. Those boards carry no bar tile and borrow nobody else’s. The Golden Gate is the one exception worth knowing: its bar is not on the Coast Guard’s page, but the weather service’s coastal waters forecast carries a San Francisco Bar section, and the San Francisco board’s marine tile carries that. It is a forecast, not an observation, so it is on the marine tile and not this one.

What makes a restriction law

All four entrances are regulated navigation areas under 33 CFR 165.1196, “Harbor Entrances along the Coast of Northern California”, in effect since August 17, 2020. The rule draws a box around each entrance channel — Humboldt Bay, Noyo River, Crescent City Harbor and, despite the section’s title, the “Estero-Morro Bay Harbor Entrance Channel” — and it defines the two words that matter:

• Restricted. The Coast Guard has prohibited recreational vessels, uninspected passenger vessels, small passenger vessels and commercial fishing vessels from operating in the area. That list is longer than people expect: on this coast a restriction covers the commercial fishing fleet too. The Captain of the Port decides when to restrict.
• Closed. The Coast Guard has prohibited all vessels from operating in the area. The rule closes a bar whenever conditions exceed the operational limits of the Coast Guard’s own search and rescue resources.
• No restrictions. Neither of those was in force when the report was made. It is not a promise that the bar is safe, and conditions on a bar can change within minutes.
• Unknown. There is no current report: the last one is more than 12 hours old, or the station is not reporting. Unknown is never an all-clear.

The Coast Guard announces restrictions and closures as a Broadcast Notice to Mariners on VHF-FM channels 16 and 22A. For Crescent City, with no report and no recorded line, that broadcast is the official word there is.

The time and the words under it

Every report carries the time it was observed, and the board shows that time and how old it is. The paragraph under a report is the watchstander’s own description — swell in each part of the channel, wind, visibility — shown exactly as they typed it, capitals and abbreviations included, because rewording a safety report is how meaning gets lost.

Before you cross

• Check the report before you leave the dock, and again before the crossing.
• When a restriction is in force, or whenever the Coast Guard is towing or escorting you across, everyone in an open part of a recreational boat must be wearing a lifejacket, and lifejackets must be readily accessible. The rule sets its own requirements for charter, passenger and commercial fishing vessels; if you run one, read it.
• For Humboldt Bay, the weather service also publishes a Humboldt Bay Entrance Channel Forecast, with its own caution that ongoing shoaling at the entrance can affect its accuracy.
• Check the marine forecast and the tide too: an ebb running against a big swell is when bars turn.
