Marine Forecast for San Jaime Bank Sep 29 – Oct 1, 2026

📋 Big swell and rising winds keep all three days a no-go

TueSep 29NO-GO

Winds are light all day (7-13 knots from the SW/W), but a persistent 6-9 foot west swell at 8-9 second periods keeps wave conditions unsafe. No long enough safe stretch for a 12-hour trip, so it's a no-go despite the calm wind.

WedSep 30NO-GO

Light-to-moderate wind (6-20 knots, mostly N to NE) can't offset building seas that grow from 6 feet to nearly 12 feet at 10-11 second periods through the day. Waves stay unsafe all 24 hours, so this is a no-go with no usable window.

ThuOct 1NO-GO

Sustained 20-25 knots E/ENE wind with gusts to 32 knots combines with massive 12-15 foot SE seas at 9-10 second periods. Every hour is rated bad for waves - this is a dangerous no-go day with zero safe window.

Persistent large west swell on Tuesday gives way to building seas and strengthening wind through Wednesday and Thursday, with Thursday bringing near-gale conditions and 14-15 foot seas. No day holds a long enough clean stretch to safely run a 12-hour trip, so this entire period is a no-go for recreational boating.

About San Jaime Bank

San Jaime Bank is one of the premier offshore grounds off Cabo San Lucas — a deep bluewater bank roughly 20 nautical miles west-southwest of Land's End that rises from the Tinaje Trough. Upwelling over the structure stacks bait and concentrates blue and black marlin, yellowfin tuna, and dorado, which is why it anchors the offshore leg of the big Cabo tournaments and fishes well all season.

It is open Pacific water with no shelter on the run out, so the forecast below is built around the two things that decide a bank trip: swell period and wind against current. Each day gets an honest GO, CAUTION, or NO-GO call — the same AI rating used in the SeaLegs AI app.

Reading conditions at San Jaime Bank

The productive bank sits about 20 nautical miles off the cape, so a San Jaime day is a real offshore commitment — a calm morning at Land's End says little about what the bank is doing by mid-afternoon. The same point where the Pacific swell wraps the cape can stand the sea up steep when wind runs against the current, so weight the swell period as heavily as the height: a long-period swell rides very differently from short, stacked wind chop at the same wave height.

Upwelling from the Tinaje Trough is what makes the bank fish — it stacks sardine, mackerel, and squid and holds marlin and tuna over the structure — but that same open-ocean exposure is why the return leg deserves as much planning as the run out. Pick the day the window stays open on both ends, and always confirm the official marine forecast and warnings before you leave the dock.

San Jaime Bank forecast FAQ

How is the sea at San Jaime Bank today?

As of Sep 29, 2026, the SeaLegs AI verdict for San Jaime Bank is NO-GO. Wind stays light and pleasant all day, easing from 13 knots SW overnight down to 7-10 knots WSW to WNW by afternoon with gusts no higher than 17 knots, and confidence in this wind forecast is high. The problem is the sea state: a long-period 6.0-8.8 foot swell at 8-9 seconds rolls in from the west and WSW all day, easing only slightly toward evening but never dropping into a safe range, so wave conditions are rated bad for nearly the entire day and only inch into caution territory after 7:00 PM. With no settled all-GO stretch long enough for a 12-hour trip, this remains a no-go day despite the calm winds - the swell alone makes it unsafe for recreational vessels.

How far is San Jaime Bank from Cabo San Lucas?

San Jaime Bank lies about 20 nautical miles west-southwest of Land's End at Cabo San Lucas — a genuine open-Pacific crossing with no shelter along the way, which is why the multi-day outlook matters more here than for nearshore trips.

What's the fishing like at San Jaime Bank?

It's a premier bluewater bank: upwelling over the structure from the Tinaje Trough stacks bait and concentrates blue and black marlin, yellowfin tuna, and dorado. It fishes all season and is one of the offshore banks the big Cabo tournaments run to.

How often is this San Jaime Bank forecast updated?

The forecast on this page is rebuilt every morning from the latest marine model data, and the SpotCast card refreshes live in your browser. The date stamp above the outlook shows exactly when it was last generated.

What do GO, CAUTION, and NO-GO mean?

GO means conditions are favorable for most recreational offshore boats. CAUTION means marginal — pay close attention to swell period and the wind trend before committing to the crossing. NO-GO means conditions are hazardous for small craft and the trip is best postponed.
