Whale watching in San Francisco: the Golden Gate and the Farallones

Whale watching in San Francisco is the least obvious of California's ports and one of the most interesting. The city looks inward at its bay, but the whales are outside the Gate, in water NOAA protects as the Greater Farallones National Marine Sanctuary — 3,295 square miles of it, running north and west from the bridge. Monterey Bay's sanctuary starts just down the coast at Rocky Point in Marin, so two of the largest protected areas in the United States effectively meet under the Golden Gate.

What that buys the visitor is range. A 2.5-hour cruise from Pier 39 reaches feeding humpbacks in a good summer. A full day gets you to the Farallon Islands, about 28 miles offshore, which the US Fish & Wildlife Service manages as a refuge closed to landing and which holds the largest seabird colony in the contiguous United States. Prices on this page start at $75 and are checked regularly.

Upwelling along this coast peaks in late spring and summer, which is when the food and the big whales arrive. Winter is a migration season rather than a feeding one.

Summer is the feeding season. Upwelling along this coast peaks from late spring, krill and anchovy follow, and humpbacks arrive behind them — sometimes close enough to the Gate that they are visible from the Marin Headlands. Blue whales are here too, but usually further out over the shelf break, which is why they belong to the full-day trips rather than the short ones.

Winter is a migration. Gray whales file south past the headlands from December and come back north with calves from February to May, traveling close to the coast. A handful enter San Francisco Bay itself most years and become local news for a week.

Fog, ebb tide and the two things that ruin a trip

San Francisco has the least dependable whale-watching weather in California, and it is worth knowing why before you book.

The first problem is fog. From June into August the marine layer can sit on the water for days. Whales are still there; you cannot see the blows. September and October are the reliable months for exactly this reason, and they are also the months when the anchovy come closest inshore.

The second problem is the Gate itself. When a strong ebb runs out of the bay against an incoming ocean swell, the water at the bridge stands up into short, steep seas for a few hundred meters. It lasts twenty minutes each way and it is where most of the seasickness on a San Francisco trip happens. Medication taken an hour before departure fixes this; medication taken when you start to feel it does not.

The third is cancellation. Operators here call off sailings for swell and visibility more often than anywhere else on this coast. Never book the boat for your last day.

The boats

The short product is a bay-and-Gate cruise: out through the bridge, work the water outside, come back. It is bookable, it is two and a half hours, and on a September morning it is all you need.

The long product is a different kind of day. Oceanic Society, a nonprofit founded in San Francisco in 1969, runs a 7.5-hour naturalist-led expedition to the Farallones at weekends from April to November. You are on the water from 8:30 in the morning until four in the afternoon, with people who can identify the seabirds as well as the whales. It is the best wildlife day available from the city and the hardest on anyone with a weak stomach.

Half Moon Bay, forty-five minutes south at Pillar Point, is the local secret. It sits outside the Gate entirely, so trips skip the tidal chaos and start already in open water.

What the day looks like

The short trip runs to a predictable shape. Boarding on the waterfront, twenty minutes across the bay with the city behind you, then the bridge — which is the photograph everybody takes and the point at which the sea changes character. Outside the Gate the boat works whatever the crew heard about that morning: a patch of feeding birds, a slick where something dived, a report from a fishing vessel.

Humpbacks here are usually feeding rather than traveling, which means they stay in one area and surface repeatedly. That is the best possible behavior for a short trip. A traveling gray whale, by contrast, gives you three blows and a dive and is a kilometer further on by the time it reappears.

The return leg is the cold one. San Francisco summers are around 17°C (63°F) in town and feel a good deal less on an open deck coming back into a north-westerly, which is why the jacket line in the budget table is not a joke.

Where you sail from

Pier 39 is the obvious base and the most expensive to park at — $25 to $40 for a half day is normal. The F-line streetcar runs along the Embarcadero to it, which makes the car unnecessary.

Leave the car at the hotel. Pier 39 is on the F-line streetcar and the parking around it is the most expensive of any whale dock in California.

GetYourGuide lists exactly one San Francisco departure — the 2.5-hour Whales of the Bay cruise at the top of this page — so the table above shows the other California products that sit outside the main harbors instead. The rest of the local market is booked direct, and the full-day Farallon expedition in particular has to be.

Who should pick what

Watching from land

Northern California has the best shore watching in the state, and San Francisco is the base for it.

Point Reyes Lighthouse, an hour and a half north, sits on a headland that juts far enough into the migration lane that gray whales pass beneath it in numbers through January and again in spring. The stairs down to the light are steep and the wind is famous; both are part of the deal.

The Marin Headlands, twenty minutes from the city across the bridge, overlook the approach to the Gate. Blows are distant but the vantage is high, which is what you want for spotting.

Lands End and the Cliff House side of the city cover the southern approach on the San Francisco shore itself, reachable on foot.

None of these replaces a boat. What they do is turn a fogged-out morning into something other than a wasted one, and they cost nothing.

The sanctuary, and the rules on the water

Official information

Greater Farallones National Marine Sanctuary

Area

3,295 square miles of open ocean and coastal waters north and west of San Francisco Bay

Designated

1981, as the Gulf of the Farallones sanctuary; renamed and expanded in 2015

Whales

Blue, gray and humpback whales, plus one of the most significant white shark populations on the planet

The islands

A national wildlife refuge about 28 miles west of San Francisco, closed to public landing — boats view from the water only

On the water

NOAA advises observing larger whales from at least 100 yards by sea or land, and keeping speeds to 10 knots or less

Source: NOAA — Greater Farallones National Marine Sanctuary. From the official source; double-check before you go.

The Farallones are the practical test of whether an operator behaves. The islands are a wildlife refuge: no landing, and boats are expected to keep their distance from hauled-out seals and from the white sharks that draw crowds in autumn. NOAA's guidance for this water asks for at least 100 yards from large whales and speeds of 10 knots or less around them.

That last number matters more than the distance. Vessel strikes, not approach distance, are what kills whales on this coast, and a boat that slows down in whale water is doing the single most useful thing available to it.

Operators on this water

Two names cover most of what is worth doing. San Francisco Whale Tours runs the short cruises from Pier 39, split between a 2.5-hour Golden Gate trip in the warmer half of the year and a longer winter version. Oceanic Society is the nonprofit with the full-day Farallon expedition and the deepest bench of naturalists in northern California.

Neither has the depth of review history you find further south. If you want a port with a dozen boats and a century of trade behind it, Monterey is two hours down the coast, and Santa Cruz sits on the same bay with a quieter harbor. The California page sets the whole coast side by side, month by month.

Sighting guarantee

No San Francisco operator guarantees a sighting, and the honest reason is the fog. What you may be offered after a blank trip is another sailing.

GetYourGuide listings

Carry the platform's cancellation terms, not a sighting promise. Read the listing's own wording before booking.

Weather cancellations

More common here than anywhere else in California. Boats are canceled for swell and visibility at the Gate several times a season.

Realistic odds

June to October outside the Gate is strong. December to February is a migration lottery decided by how close the grays are running.

Build a spare day into the plan. A canceled sailing is far more likely than an empty one here.

Our call

A September morning cruise outside the Golden Gate

Humpbacks feeding on anchovy close in, the fog usually gone, and the bridge on the way out.

Skip it if Booking the only day of your trip. San Francisco cancels for weather more often than any other California port.

Check San Francisco dates from $75

San Francisco is not the place to book a whale trip on a fixed date and hope. It is the place to keep an eye on the forecast, take the first clear morning in September or October, and go out under the bridge into two sanctuaries' worth of water. On the right day it is the most spectacular setting for whale watching anywhere in the state. On the wrong one you will not see the bridge, let alone a blow.
