Marine Forecast for San Jaime Bank Nov 15–17, 2026
📋 NO-GO: very large WNW swell makes seas dangerous
NO-GO all day. Winds ease from 11 knots NNW to near calm, but a WNW swell builds from 8 to over 10 feet at 13-15 seconds. Seas are rated bad every hour, so stay ashore.
NO-GO all day. Winds are very light (3-6 knots, variable), but a WNW swell of 10.7 feet at 15 seconds only slowly eases to about 8 feet. Seas rate bad every hour; low confidence adds uncertainty.
NO-GO all day. Light W-WNW winds of 2-5 knots, rising to 9 knots NW late, but a WNW swell of 7.6-8.6 feet at 13-14 seconds keeps seas rated bad. No usable window for a 12-hour trip.
Winds are light all three days (generally under 11 knots), but a powerful west-northwest swell of 8 to 11 feet at 13 to 15 second periods keeps seas rated bad every hour. The wave field is the limiting factor and no settled stretch is long enough for a 12-hour trip on any day. Model agreement on wave height is poor (16-37% confidence), so actual seas could differ from the forecast.

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 Nov 15, 2026, the SeaLegs AI verdict for San Jaime Bank is NO-GO. NO-GO all day. Winds are light to moderate, starting at 10-11 knots from the NNW with gusts to 15 knots and easing to 2-3 knots by mid-afternoon. The problem is a large WNW swell building from 8 feet at 13-second periods around midnight to over 10 feet at 15-second periods by evening, rated bad every hour. Even though the long period spreads the energy out, the sheer size makes open-water conditions dangerous for recreational vessels. There is no safe window for a 12-hour trip. Model confidence is moderate at 69%, with wave height the least certain parameter.
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?

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.
