The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for the next couple of weeks.
Right off the bat, I’ve got to be straight with you: it’s looking pretty bleak. There’s a real dry spell on the surf front, and for the next several days at least, there’s just nothing worth paddling out for. We’re kicking off on Monday the 17th of August at Cabo Blanco and honestly, it’s a rough start. We’ve got a weak, short-period 3ft swell from the SSW, but it’s getting hammered by a 22 mph cross-shore wind. The water is a warm 77°, which is far warmer than normal for this time of year, but that doesn’t help the mess. The combined wave energy is weak (37), and the conditions are just poor.
That sets the tone for pretty much the whole outlook. For days after that, we’re stuck with tiny, inconsistent pulses – mostly under 2ft – and a lot of cross-shore breezes. Tuesday the 18th through to the end of the month sees one near-flat day after another. The combined energy levels are almost always in the double digits (between 3 and 39), which is weak. The swell direction rarely matches what this point wants – it needs a proper NNW to really fire, but we’re mostly getting short-period SW windswell.
There are a couple of faint flickers in the long-range. On Saturday the 29th of August, we see a little pulse from the WNW, but it’s only 0.7ft to 2ft. Then on Monday the 31st, there’s a spike in period – a 0.7ft swell from the WSW with a 19-second period. That’s a very long-period groundswell, and combined energy hits 41. That’s still weak, and the wind is cross-shore, but that long period means if *anything* lines up, the point might produce a rare, clean little wave. It’s a distant hope.
Overall, the breaks are fairly consistent, but the surf just isn’t there. There are no standouts here – nothing even close. For the first week and a half, you’re better off staying home or finding another hobby. The second week holds a whisper of potential, but it’s too early to get excited.
Rusty.

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.
