The Lowdown

Alright, let's talk surf. This is Rusty.

Thursday the 27th of August is a total wash at *Cabo Blanco*. There’s a little 1ft southwest groundswell with a long 18-second period, but the wind is howling cross-onshore with storms around. Water temp is a balmy 86°, running a touch warmer than normal for the season, but it doesn’t help the conditions. It’s just ugly.

Friday the 28th morning flips the script. The wind goes dead calm, glassy as a mirror, and the same southwest swell bumps up to 2ft with a 20-second period. That’s a real long-period groundswell, and in clean glass, it’ll set up nicely. Combined energy is moderate at 349. The session is short-lived though – by Friday afternoon the onshore wind kills it.

Saturday the 29th morning is the one to circle. Swell hits 4ft from the southwest, still a long 16-second period, and glassy conditions. Combined energy jumps to 683, which is a proper moderate push. That’s the best looking morning of the first week. Saturday afternoon gets cross-onshore again.

Sunday the 30th morning repeats the trick: glassy, 4ft southwest swell, 14-second period, energy at 738. Again, early is key. Monday the 31st starts to drop off, with cross-onshore wind and smaller swell.

Tuesday the 1st of September has a glassy early window with 3ft southwest swell, 12-second period. Good for a log. Then we get a run of clean mornings that all have potential: Wednesday the 2nd morning, light offshore from the north, 3ft south-southwest swell; Thursday the 3rd morning, glassy, 2ft south-southwest; Friday the 4th morning brings back 4ft southwest swell and glass, energy at 824 – that’s a strong, clean session.

Saturday the 5th of September morning is another standout. 4ft southwest swell, glassy, combined energy at 924 – that’s strong wave energy, and it will be firing with clean faces. Sunday the 6th has another glassy 4ft morning. The middle of the week gets smaller and more mixed.

Then comes the late run. Wednesday the 9th morning: 3ft southwest, 18-second period, glass, energy 783. Thursday the 10th morning: 4ft southwest, 16 seconds, glass, energy 773. Friday the 11th morning: 4ft southwest, 15 seconds, glass, energy 655. All of those are quality mornings.

Best of the best? Saturday the 29th of August and Saturday the 5th of September. Both glassy, both solid southwest swell, and the energy numbers don't lie – there's proper power in the water.

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.
