The Lowdown
Alright, your local surf reporter Rusty here. Let's have a look at what's cookin' for the next couple of weeks.
It's a bit of a slow-burner, this one. We've got a solid run of clean, small-to-medium SW groundswells on the cards, but nothing that's gonna shake the doors off. The real story is the consistency of the wind – a whole lot of glassy mornings, which is a beautiful thing for a spot like this.
Kicking things off, we're looking at a bit of a slow start on Tuesday, the 1st of September. The morning has a little 3ft SW swell (348 energy units) but it's a bit messy with a cross wind. The afternoon is even worse with a choppy cross-on, so forget about it. We'll just have to wait.
Wednesday the 2nd of September is where it starts to get interesting. That morning is pure gold: 3ft of clean SSW groundswell and a dead flat, glassy ocean. That's a 394 energy reading on the swell, so there's a bit of push in the water. The period is a lovely 13 seconds, so you'll be getting some proper lines. This is a standout session for the lighter boards.
Thursday the 3rd morning is another glassy gem, with 2ft of SW groundswell and a 16-second period that'll wrap in nicely. The energy is a bit lower at 350, but it'll be clean. Friday the 4th is the real highlight though. That morning is calling for 4ft of SW groundswell with a 17-second period, and the energy jumps to 962. It's glassy, it's got power, and it's going to be really good. That's the best on offer for the trip.
The run continues into the weekend. Saturday the 5th and Sunday the 6th both have glassy mornings with 4ft and 4ft of SW groundswell respectively. The energy is still strong (around 892 and 678), so you'll get some fun, punchy walls. The afternoons get a bit junked up by the wind, so stick to the early sessions.
Next week, Monday the 7th and Tuesday the 8th keep the pattern going. Glassy mornings, with 3ft and 2ft of swell. The Tuesday morning session has a super long 18-second period and 630 energy, so it'll be a bit more lined up but still clean. The surf stays small but clean through the middle of the week, with Wednesday the 9th and Thursday the 10th offering more glassy mornings. That Thursday the 10th morning has a nice 3ft of 15-second SW swell and 644 energy – another solid call.
The second week starts to fade a bit. Friday the 11th and Saturday the 12th still have small but clean morning waves, but the energy is dropping. Sunday the 13th and Monday the 14th are really small, with 2ft and 1ft of swell. The energy is weak, but the glass is still there. The tail end of the forecast, Tuesday the 15th and Wednesday the 16th, is just tiny, clean leftovers. The swell is small but the period is still long, so there might be a micro-session on the 16th with a 2ft S swell and 18-second period.
Overall, the standout is the morning of Friday the 4th of September. You get the best combo of swell size, long period, and glassy conditions. The water temp is about average for the time of year, so no need for a wetsuit.
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.
