The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s comin’ down the line for Cabo Blanco.
We’ve got a run of small, clean surf stretchin’ out for the next couple of weeks. It ain’t gonna blow your mind, but for the patient surfer, there’s some real quality windowpanes in there. The combined energy of all swells directed here stays moderate (202 to 654) for the first week, with a couple of bigger pulses later on. The real standout is the morning of Saturday the 15th of August, with glassy conditions, a clean 4ft SW swell, and a very good energy reading (917). That’s the pick of the whole period.
Let’s start at the beginning. Thursday morning the 6th of August, we’re seein’ a tiny 1ft SSW swell with a very long period of 15 seconds. The water is about average for this time of year. The wind is glassy out of the SSW at 3 mph. It’s small, but it’s clean. That afternoon stays glassy with a 2ft SSW swell. Friday the 7th is a similar story – glassy morning, 2ft SSW swell, long period at 18 seconds. The afternoon gets a little questionable with a light onshore breeze.
Saturday the 8th of August is where it starts to get interesting. The morning is glassy, the swell bumps up to 4ft from the SW with a 16-second period, and the combined energy is strong (654). That’s a solid morning. The afternoon turns poor with a risk of thunderstorms and a cross-onshore wind. Sunday the 9th cleans up again with glassy conditions in the morning and a 3ft SSW swell. The wind goes dead calm in the afternoon. Beautiful.
The first week of the period is all about these small, glassy mornings. The swell is consistently SW to SSW, around 2ft to 4ft, with periods that are long enough to give the waves some shape. It’s a classic Cabo Blanco run of clean, small waves. The best of that first week? Saturday morning the 8th of August, no question.
Now, rollin’ into the second week. Monday the 11th of August is glassy in the morning with a 2ft SW swell, 18-second period. The energy is moderate (329). The morning of the 12th is dead calm, with a 2ft SW swell. The 13th has a glassy morning too, 2ft SSW swell. On the 14th, the swell pushes up to 3ft SW, but we get some cross-onshore wind and the energy jumps to 821 – moderate to strong.
Then we hit the big one. Saturday the 15th of August. The morning is glassy, the swell is 4ft from the SW with a 16-second period, and the combined energy is strong (917). That’s the best look of the whole 16-day run. For a more experienced surfer, that’s a proper session. Sunday the 16th of August is also a beauty – glassy in the morning, same 4ft SW swell, and a clean offshore wind in the afternoon. The energy is still strong (643).
The rest of the period from the 17th to the 21st of August stays in the 3ft to 4ft range, mostly SW swell, with plenty of glassy mornings. The crowds here are described as “sometimes,” so you might have a few locals out, but it’s nothing crazy. The break is fairly consistent, so there’s almost always a wave to be had.
One last thing: Friday the 21st of August. The morning shows a 5ft SSW swell with a 15-second period. The combined energy hits 1117. That’s strong to very strong energy. The wind is glassy. This is excellent surf, but at 5ft, it’s gettin’ a bit big for beginners. For the experienced surfer, that’s a proper session to circle on the calendar.
So, for the best surf on offer: lock in Saturday morning the 15th of August for the best combination of size, power, and glassy conditions. Saturday the 8th of August is a close second for the first week. The rest is small, clean, and consistent for the patient surfer.
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.
