Cabo San Lucas Marine ForecastLand's End, Baja California Sur

As of Oct 11, 2026, the SeaLegs AI verdict for Cabo San Lucas is NO-GO. NO-GO all day Sunday. Winds are very light (2 to 5 knots from the northwest, shifting through the south and west by afternoon) but waves are the problem: a 6.2 to 6.6 foot swell from the south at 11-second periods is crossing the wind-wave, which turns from the west. This SE swell crossing W wind-wave setup creates a confused cross-sea, with two wave trains arriving from different directions, awkward uncomfortable motion, and no single good heading. Waves rate bad until about 10:00 PM and only ease to caution late evening, with no settled stretch long enough for a 12-hour trip. Model agreement on wind speed is low, so wind shifts could differ from the forecast.

The board above shows today's conditions at the harbour mouth at Land's End — wind, swell, and a plain GO, CAUTION, or NO-GO rating — rebuilt every morning from the latest marine model data. Because the Pacific and the Sea of Cortez meet at the cape, treat it as the departure read rather than a single number for every direction you might run.

Land's End is the dividing point between open Pacific water and the Sea of Cortez. The Pacific side takes the ocean swell and is where the offshore banks sit; the Cortez side is often calmer in summer and autumn but is the rougher one in winter, when northerlies funnel down the gulf. It is common for one side to be fishable and the other not on the same morning.

Golden Gate Bank lies about 17 nautical miles west-northwest of Land's End and San Jaime Bank about 20 nautical miles west-southwest — both open-Pacific runs with no shelter along the way. The Gordo Banks sit the other way, up the Sea of Cortez side.

It depends on the fish. Blue and black marlin peak from roughly July through October, which is why the big-money tournaments run in October — the overlap weeks when marlin, yellowfin tuna, dorado and wahoo are all in the water together. Striped marlin are the area's most abundant billfish but peak in the cooler months, roughly December through June.

GO means conditions are favorable for most recreational boats. CAUTION means marginal — manageable for experienced crews in capable vessels, but check the wind, swell period, and timing closely. NO-GO means conditions are hazardous for small craft and the trip is best postponed.
