Marine Forecast for San Jaime Bank Sep 11–13, 2026
📋 Light winds all weekend, but crossing swell/wind-wave creates choppy seas
Light 5-10 knot N/NW winds and 4-4.5 foot SW swell at 10-11 seconds, but a crossing NW wind-wave creates a confused, choppy sea for several hours. Early morning (before 9:00 AM) is the smoothest window; afternoon/evening gets bumpier as wind builds.
Winds 7-12 knots NW/NNW with gusts to 16 knots and 4-4.3 foot seas at 8-9 seconds. A crossing SSW swell and NW wind-wave keep the sea confused almost all day - the choppiest day of the weekend. Midday (11:00 AM-1:00 PM) offers the calmest wind, but expect a jumbled ride.
Light 8-12 knot NW winds and 4-4.4 foot WSW/SW seas at 8-second periods, but a crossing SSW swell keeps the sea confused for about 11 hours. Conditions smooth out nicely by evening, with 8:00 PM-11:00 PM the top pick for departure.
Wind stays light (5-12 knots) and waves stay under 5 feet all three days, but a persistent SSW swell crossing a NW-to-WNW wind-wave sets up a confused, uncomfortable cross-sea for long stretches each day. Boats will be fine from a raw wind/wave-height standpoint, but the mismatched wave trains mean no single heading feels smooth, so caution is warranted rather than an outright GO.

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 11, 2026, the SeaLegs AI verdict for San Jaime Bank is CAUTION. Winds stay light all day, generally 5-10 knots from the N/NNW/NW with gusts up to 14 knots by evening, and seas hold near 4.1-4.5 feet at long 10-11 second periods from the SW. Despite these comfortable numbers, a steep wind-wave chop develops for about 5 hours and a confused cross-sea persists for roughly 11 hours as the NW-to-WNW wind-wave crosses the long-period SW swell, producing an awkward, uncomfortable motion with no single ideal heading. Best window is the early morning hours (12:00 AM-9:00 AM) when winds are lightest and the sea state is most settled; expect the ride to get choppier through the afternoon and evening as NW winds build toward 10 knots with gusts to 14 knots.
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.
