The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
We’re starting a bit slow with a few days of pretty average conditions. The first real chance to get wet comes on Thursday the 6th. The swell is tiny, around 1 ft to 2 ft, but it’s a nice long period groundswell from the SSW. The wind is glassy in the morning, and the combined energy is moderate (200). It’s not going to be epic, but it’s a start.
The real standout comes on Saturday the 8th. The morning session is where it’s at. We’ve got a 4 ft SW swell, with a period of 16 seconds – that’s proper groundswell. The wind is dead calm, just glassy. The combined energy is strong (655). This is the pick of the first week. Cabo Blanco is fairly consistent, and with a NE offshore wind predicted, it should be lining up nicely. The water is a touch warmer than normal at 86°, which is nice.
After that, the mornings stay clean through the 10th and 11th, with smaller swells in the 2 ft to 2 ft range, but still glassy. The 11th afternoon gets a bit choppy with a cross-onshore wind, so aim for the early bird slots.
Looking further out, the following week has some serious potential. The morning of Friday the 14th of August looks special. We’re looking at 3 ft of SW swell, but the period is a very long 18 seconds, and the combined energy is strong (666). The wind is glassy. This is a classic point-break style swell – long, powerful lines.
Then, the morning of Saturday the 15th of August is a strong contender for the best of the whole run. It’s 4 ft of SW swell, again 16-second period, and the combined energy is very strong (710). Glassy conditions again. This is a lot of energy for a 4 ft wave, meaning it’ll have some punch. The 16th of August also has a glassy morning, with 3 ft of SW swell and a combined energy of 557 (strong). Mornings are the key, as the afternoons get a bit messy with cross-onshore winds.
Overall, the first week is a slow build, but the second week – particularly the mornings of the 14th, 15th, and 16th of August – is where the real magic is. Get your board ready for those.
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.
