The Lowdown

G’day, Rusty here. We’ve got a solid run of surf on the cards at Cabo Blanco, starting from this Sunday morning. The overall pattern is a consistent pulse of south-west groundswell, hanging around for a good stretch, with plenty of clean windows if you pick your moments.

Sunday, 30 August kicks things off proper. Early morning is the standout – we’re looking at a clean 4ft swell from the SW, with a long 14-second period and glassy conditions. The combined energy is moderate at 734, and that calm wind is a major positive, meaning those lines will be clean and inviting. This is one of the best sessions on offer, no doubt. The water temp is about average for this time of year. As the afternoon rolls in, the wind swings onshore from the WSW at 6 mph and the swell drops a touch, so the morning window is the one to nail.

Monday, 31 August is a bit of a write-off. The wind is cross-onshore all day, building to 9 mph in the arvo, and the swell dips to 3ft or less. The surf gets choppy, so you’re better off sitting this one out.

Tuesday, 1 September dawns with another glassy morning, a light 3ft SW swell, and a 12-second period. It’s not huge, but it’s clean and fun. The afternoon stays glassy too with a slight air, so there’s a whole day of small, clean waves if you’re keen on a longer session.

Wednesday, 2 September morning is glassy again, with a 3ft SSW swell, but the standout here is the 17-second period in the afternoon – that’s some serious groundswell energy, even if the size is only 2ft. The wind goes cross-onshore though, so it’s a bit of a tease.

Thursday, 3 September morning is dead calm and glassy with a 2ft, 16-second swell. Clean but small.

Friday, 4 September is where it picks back up. The morning glassy session brings a 4ft SW swell with a 17-second period, and the energy jumps to 973 – moderate but pushing strong. This is another top pick: clean, solid lines. The afternoon sees an onshore breeze, so get it early.

Saturday, 5 September morning is glassy again, with a 4ft SW swell and a 16-second period, energy at 934. This is the second standout – similar size and quality to Sunday morning, just a week later. The afternoon goes onshore, so it’s a morning mission.

Sunday, 6 September starts with light cross-onshore wind, and the swell is still a clean 4ft, but that breeze will put a few bumps on the face. It’s not the best, but still rideable for those who don’t mind a bit of texture.

From Monday, 7 September onward, the surf settles into a pattern of smaller, cleaner mornings with glassy conditions, but the size drops below 3ft. The energy is moderate but the quality is good for a longboard or a funboard. The highlight in this second week is Friday, 11 September morning – a 3ft SW swell, 16-second period, and dead calm winds. Clean and inviting. Also worth a mention is Tuesday, 8 September morning, with a 2ft, 18-second period swell – very long lines, but small. That long period will make it a bit straight at the beach, but the point setup at Cabo Blanco (Peru) should handle it nicely.

Crowds are possible here – it says “sometimes” – so don’t expect to have it all to yourself, especially on those standout mornings.

Overall, the best bets are Sunday 30 August and Saturday 5 September mornings. Go get it.

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.
