Marine Forecast for Cabo San Lucas Sep 11–13, 2026
📋 Light winds all weekend, but crossing swell creates awkward chop
Light winds (under 6 knots) and modest 3.5-3.8 ft SSW swell at long periods, but a crossing WNW wind-wave creates a confused, occasionally awkward sea. Best conditions are the calm overnight-to-morning hours and mid-afternoon; expect some uncomfortable motion at times regardless of heading.
Calm morning winds give way to a breezier SW-WSW afternoon (up to 9 knots, gusts to 18), while a persistent SSW swell crosses the WNW/W wind-wave for a long confused-sea period. Waves stay under 3.5 feet, but the crossing pattern makes for awkward motion, especially afternoon.
Lightest wind and smallest waves of the weekend (3.0-3.2 ft), but the SSW swell still crosses the WNW/NW wind-wave for a confused, choppy stretch of the day. Morning is calmest; afternoon SW winds build to 8-9 knots with gusts to 17, adding to the awkward motion.
Wind stays light (under 10 knots) and waves stay under 4 feet all three days, but a persistent SSW swell crossing the WNW-to-NW wind-wave direction creates a confused, uncomfortable sea state each day. Conditions are technically calm on paper, but the mismatched wave trains mean caution and careful timing are warranted rather than an unqualified go.

About Cabo San Lucas
Cabo San Lucas sits at the very tip of Baja California Sur, where the Pacific meets the Sea of Cortez at Land's End — and that meeting point is exactly why one number for "Cabo" misleads. A morning that is glassy inside the bay can be a stiff, lumpy ride the moment you round the point and turn up the Pacific side.
This page reads the water at the harbour mouth itself, where every trip starts and finishes. Each day gets an honest GO, CAUTION, or NO-GO call, rebuilt every morning from the latest marine model data — the same AI rating used in the free SeaLegs AI app.
Reading the water at Land's End
Two different oceans meet at the cape, and they rarely behave the same way on the same day. The Pacific side takes the open swell and is where the offshore banks sit — Golden Gate about 17 nautical miles west-northwest and San Jaime about 20 nautical miles west-southwest, both seamounts whose upwelling stacks bait. The Sea of Cortez side, up toward the Gordo Banks, is generally the more sheltered option when the Pacific stands up — which makes the decision at Land's End less "can I go" than "which way do I turn".
Season matters as much as the daily number. Late summer into autumn is the tail of the eastern Pacific hurricane and tropical-storm season, and a system still far offshore can lay a long southerly groundswell on the cape under a clear sky and a light breeze — which is why swell period deserves as much weight as height here. A long-period swell rides very differently from short wind chop at the same reading. In winter the pattern flips: northerlies funnel down the Sea of Cortez and it is the Cortez side that turns uncomfortable. Plan the whole day rather than just the departure, and always confirm the official marine forecast and warnings before you leave the dock — this page is a planning aid, not a substitute for them.
Cabo San Lucas forecast FAQ
How is the sea at Cabo San Lucas today?
As of Sep 11, 2026, the SeaLegs AI verdict for Cabo San Lucas is CAUTION. Winds stay very light all day, generally under 6 knots from the WNW to NNW with gusts only reaching into the low teens by early afternoon, and seas hold around 3.5-3.8 feet at long 9-11 second periods from the SSW. Despite the calm numbers, this SSW swell crosses the WNW wind-wave direction for a good stretch of the day, producing a confused cross-sea where the two wave trains meet at odds - expect an awkward, occasionally uncomfortable motion with no single heading that smooths it out. Visibility is excellent at 10 miles, and this remains the most benign of the three days, but plan for that underlying chop, especially through midday.
What is the marine forecast for Cabo San Lucas today?
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.
Why can conditions differ so much on either side of Cabo?
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.
How far are the offshore banks from Cabo San Lucas?
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.
When is the best fishing season at Cabo San Lucas?
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.
How often is this Cabo San Lucas 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 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.
