The Lowdown
Righto, let’s have a look at what’s cookin’ for Cabo Blanco over the next couple of weeks. This spot is exposed to the SW, and the optimum swell direction is SW too, so that’s a good sign when the energy lines up right.
Water temp is sittin’ at 86°, which is a touch warmer than normal for this time of year – you’ll feel that extra bit of bathwater warmth on the early glassy sessions.
The first decent window opens up Tuesday morning the 4th. We’ve got a glassy 3ft SSW swell, period around 9 seconds, and the combined swell energy is moderate at 251. Winds are light from the west, almost nothing, so conditions are looking clean. It’s not huge but it’s rideable and the surface will be smooth. That’s about as good as it gets for the start of the run.
From Tuesday afternoon through Wednesday, things drop off quick. The wind goes onshore or cross, the swell gets messy, and the scores reflect that – not worth paddlin’ out for.
Thursday morning the 6th is small – 1ft with a long 15 second period – but it’s glassy again. That kind of period from a SSW direction can produce nice lines, but the size is tiny. Still, if you’re on a log, there might be something there. The afternoon builds slightly to 2ft with 14 seconds and 243 energy, still glassy.
Now, Friday the 7th is where it gets interesting. Morning glass, 2ft SSW swell but a very long period of 18 seconds. The combined swell energy jumps to 450 – that’s moderate but with that kind of period, the quality goes up. For a beach setup, that long period can make things a bit straight, but at Cabo Blanco it might still offer some nice lines if you pick the right bank.
Saturday the 8th is the standout of the whole forecast. Morning session: 4ft SW swell, 16 second period, combined energy at 653 (strong). Glassy conditions with the lightest of airs. That’s the kind of morning you set the alarm for. The swell direction matches the optimum SW, the period is long, and it’s clean. Could be some really nice waves.
Sunday the 9th still has some good energy – 3ft, 14 seconds, glassy morning – but it’s not quite the peak of Saturday.
Monday the 10th and Tuesday the 11th both offer glassy mornings with smaller SSW swell, 2–2ft, but with 13–14 second periods. Energy stays moderate. Worth a look if you’re keen.
Wednesday the 12th morning is clean again, 2ft, 16 seconds, 344 energy – still fun.
Thursday the 13th to Friday the 14th: the morning glass continues. Friday the 14th morning has 2ft but a 19-second period – very long – and 487 energy. That’s groundswell energy, but it’s small. Might be a bit too straight for the beach, but if there’s a bank or a corner, it’ll have push.
Now Saturday the 15th – another standout. Morning glass, 4ft SW swell, 16 seconds, combined energy at 744 (strong). That’s right up there with the 8th. The wind is light from the NW, glassy. This is the second big morning to circle.
Sunday the 16th: morning glass, 3ft SW, 15 seconds, 605 energy. Clean and solid.
Monday the 17th and Tuesday the 18th mornings stay glassy with 3–3ft SSW swells and 13–15 second periods. Energy stays moderate to strong.
Wednesday the 19th morning: 3ft SW, 14 seconds, 499 energy, glassy again. The run just keeps giving.
Overall, the first week has a few small windows but Saturday the 8th and Saturday the 15th are the real standouts – both have 4ft SW swell, long period, strong energy, and glassy conditions. Those are your sessions.
Crowds can pop up here sometimes, so if you can get out early on those standout mornings, you’ll have it cleaner.

Information about the Cabo Blanco Surf forecast
The above surf forecast table for Cabo Blanco provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cabo Blanco can be found by selecting the local surf guide option on the grey menu. Our Cabo Blanco surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Cabo Blanco) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Cabo Blanco may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
